Older passerines have been discovered before, including 55-million-year-old fossils found in Australia, but those earlier versions weren't capable of eating seeds, munching instead of fish and insects.
|
|
Also known as passerines, these birds are distinguished by the arrangement of their toes, in which three point forward and one points back—an orientation that, as the name suggests, is amenable to perching.

It was, in any case, ten times as many as he had ever seen in a day, and, he thought, the most passerines, or perching birds, ever seen in one day in North America.

"I think the biggest revelation from these new fossils is that we know know that early passerines very quickly evolved beak shapes to eat all types of food like seeds, insects, and nectar," said Ksepka.

"In birds, captive parrots have been reported to scratch with sticks, but to date the only avian tool use for physical maintenance reported in the wild is 'anting' (depositing ants on one's plumage), observed in many species," mostly passerines, or "perching birds," the scientists note.

All near passerines are land birds. However, molecular data does not support the traditional arrangement; it is now clear that "near passerines" and "higher landbirds" are not synonymous. Per Ericson and colleagues, in analysing genomic DNA, revealed a lineage comprising Passeriformes, Psittaciformes and Falconiformes.

"Near passerines" and "higher land-bird assemblage" are terms of traditional, pre-cladistic taxonomy that have often been given to tree-dwelling birds or those most often believed to be related to the true passerines (order Passeriformes) owing to morphological and ecological similarities; the group corresponds to some extent with the Anomalogonatae of Alfred Henry Garrod.

The passerines contain several groups of brood parasites such as the viduas, cuckoo-finches, and the cowbirds. Most passerines are omnivorous, while the shrikes are carnivorous. The terms "passerine" and "Passeriformes" are derived from the scientific name of the house sparrow, Passer domesticus, and ultimately from the Latin term passer, which refers to sparrows and similar small birds.

Other medium-sized to largish-bodied families of passerines tend to be most often selected. In many circumstances, Cooper's hawks will hunt corvids, large, intelligent and social passerines, with the smallish jays being particularly popular. In Missouri, the most often selected prey (12.7% of 259 prey items) was the blue jay (Cyanocitta cristata), which also important in northern Florida, i.e. 12.27% of 1100 prey items.

Guillemot eggs The default color of vertebrate eggs is the white of the calcium carbonate from which the shells are made, but some birds, mainly passerines, produce colored eggs. The pigment biliverdin and its zinc chelate give a green or blue ground color, and protoporphyrin produces reds and browns as a ground color or as spotting. Non-passerines typically have white eggs, except in some ground-nesting groups such as the Charadriiformes, sandgrouse and nightjars, where camouflage is necessary, and some parasitic cuckoos which have to match the passerine host's egg. Most passerines, in contrast, lay colored eggs, even if there is no need of cryptic colors.

Like many small birds, the purple-crowned fairy uses considerable amounts of spider silk in its cup nest. The cup nest is smoothly hemispherical inside, with a deep depression to house the eggs. Most are made of pliable materials—including grasses—though a small number are made of mud or saliva. Many passerines and a few non-passerines, including some hummingbirds and some swifts, build this type of nest.

During the winter, they will both have a rufous colouration in the back. In the spring, the buntings will not go through a moult as other passerines birds do, instead the breeding colouration comes with the wearing and abrasion of the feathers. Unlike most passerines, it has feathered tarsi, an adaptation to its harsh environment. No other passerine can winter as far north as this species apart from the common raven.

Clutches vary considerably in size: some larger passerines of Australia such as lyrebirds and scrub-robins lay only a single egg, most smaller passerines in warmer climates lay between two and five, while in the higher latitudes of the Northern Hemisphere, hole-nesting species like tits can lay up to a dozen and other species around five or six. The family Viduidae do not build their own nests, instead, they lay eggs in other birds' nests.

The chicks of passerines are altricial: blind, featherless, and helpless when hatched from their eggs. Hence, the chicks require extensive parental care. Most passerines lay coloured eggs, in contrast with nonpasserines, most of whose eggs are white except in some ground-nesting groups such as Charadriiformes and nightjars, where camouflage is necessary, and in some parasitic cuckoos, which match the passerine host's egg. The vinous-throated parrotbill has two egg colours, white and blue, to deter the brood parasitic common cuckoo.

A Field Guide to Australian Birds is a two-volume bird field guide published by Rigby of Adelaide, South Australia, in its Rigby Field Guide series. The first volume (Volume One: Non-Passerines) was issued in 1970, with the second volume (Volume Two: Passerines) appearing in 1974. It was Australia’s first new national bird field guide since the 1931 publication of the first edition of Neville Cayley’s What Bird is That?. It was principally authored by Australian ornithologist, artist and photographer Peter Slater.

Passerines have low site fidelity because they can be flexible in their habitat selection. Since they do not migrate in flocks, migratory passerines do not have a fixed migration route or stop-over site sequence and they can change their stopover sites based on wind selectivity or habitat quality. Even though many birds can change their stopover sites, birds such as swans and waders depend on wetland stopover sites to 'refuel' on migration. The destruction of these sites could therefore be detrimental to bird populations.
|

Medium-sized passerines in particular may be slightly preferred, with a wide array of thrushes, jays and icterids hunted. Common birds like the northern cardinal and the American robin are taken fairly regularly when opportuned upon. Smaller passerines, often around the same size as the mice and voles popular in the diet, are also regularly reported as prey. Conspicuous nesting sites of barn swallow and purple martin on manmade structures and objects were revealed via video-monitoring to suffer heavy predation by barred owls.

Fig. 1: Great tit (Parus major) The great tit, Parus major, is a passerine bird belonging to the family Paridae. Passerines are commonly referred to as songbirds, with most passerines singing multiple species-specific songs making a repertoire. Birds can be ranked depending on how they perform the songs in their repertoire. On one side, there are birds that sing with eventual variety and have small repertoires, meaning that each song type in their repertoire is repeated before they switch to a different song type.
|
|
This is likely due to the fact that the larger passerines usually roost in relatively open spots and have larger, more conspicuous nests. Crows and ravens tend to be grabbed off of their communal roosts by night.

The New Zealand wrens are a family (Acanthisittidae) of tiny passerines endemic to New Zealand. They were represented by six known species in four or five genera, although only two species survive in two genera today. They are understood to form a distinct lineage within the passerines, but authorities differ on their assignment to the oscines or suboscines (the two suborders that between them make up the Passeriformes). More recent studies suggest that they form a third, most ancient, suborder Acanthisitti and have no living close relatives at all.
|
|
The Hirundinidae have an evolutionarily conservative body shape, which is similar across the clade, but is unlike that of other passerines. Swallows have adapted to hunting insects on the wing by developing a slender, streamlined body and long, pointed wings, which allow great maneuverability and endurance, as well as frequent periods of gliding. Their body shapes allow for very efficient flight; the metabolic rate of swallows in flight is 49–72% lower than equivalent passerines of the same size. The bill of the sand martin is typical for the family, being short and wide.

A passerine is any bird of the order Passeriformes (Latin passer (“sparrow”) + formis (“-shaped”)), which includes more than half of all bird species. Sometimes known as perching birds or songbirds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and among the most diverse orders of terrestrial vertebrates. Passerines are divided into three suborders: Acanthisitti (New Zealand wrens), Tyranni (suboscines) and Passeri (oscines).
|
|
The first passerines are now thought to have evolved in the Southern Hemisphere in the late Paleocene or early Eocene, around 50 million years ago. The initial split was between the New Zealand wrens (Acanthisittidae) and all other passerines, and the second split involved the Tyranni (suboscines) and the Passeri (oscines or songbirds). The latter experienced a great radiation of forms out of the Australian continent. A major branch of the Passeri, parvorder Passerida, expanded deep into Eurasia and Africa, where a further explosive radiation of new lineages occurred.

Both adults brood and feed the chicks, which fledge in an average 40.5 days. Swifts as a family have smaller egg clutches and much longer and more variable incubation and fledging times than passerines with similarly sized eggs, resembling tubenoses in these developmental factors. Young birds reach a maximum weight heavier than their parents; they can cope with not being fed for long periods of time, and delay their feather growth when undernourished. Swifts and seabirds have generally secure nest sites, but their food sources are unreliable, whereas passerines are vulnerable in the nest but food is usually plentiful.
|
|
After about 50days, the chicks are fed less regularly, sometimes with gaps of several days, and the parents may stop visiting completely shortly before the chick leaves the nest. The chicks fledge about 56–86days after hatching, and receive no parental support after leaving the nest hole. Tubenoses have smaller egg clutches and much longer and more variable incubation and fledging times than passerines with similarly sized eggs, resembling swifts in these developmental factors. Tubenoses and swifts have generally secure nest sites, but their food sources are unreliable, whereas passerines are vulnerable in the nest but food is usually plentiful.

It is a non- profit endeavour fuelled by material from more than one hundred contributors from around the world. In early 2013, Lynx Edicions launched the online database HBW Alive, which includes the volume and family introductions and updated species accounts from all 17 published HBW volumes. Since its launch, the taxonomy has been thoroughly revised and updated twice (once for non- passerines and once for passerines), following the publication of the two volumes of the HBW and BirdLife International Illustrated Checklist of the Birds of the World. The Handbook of the Birds of the World Alive site also provides a free access 'Key to Scientific Names in Ornithology'.

Nests can become home to many other organisms including parasites and pathogens. The excreta of the fledglings also pose a problem. In most passerines, the adults actively dispose the fecal sacs of young at a distance or consume them. This is believed to help prevent ground predators from detecting nests.

The pilotbird is a large, plump species of acanthizid, measuring around in length and weighing . The plumage of the underparts is reddish-brown with scalloping on the chest and the centre of the belly speckled dull white. The upperparts are chocolate- brown.Slater, Peter (1974) A Field Guide to Australian Birds: Passerines.

In the Caucasus, jackals mainly hunt hares, small rodents, pheasants, partridges, ducks, coots, moorhens and passerines. They readily eat lizards, snakes, frogs, fish, molluscs and insects. During the winter period, they will kill many nutrias and waterfowl. During such times, jackals will surplus kill and cache what they do not eat.

The heaviest and altogether largest passerines are the thick- billed raven and the larger races of common raven, each exceeding and . The superb lyrebird and some birds-of-paradise, due to very long tails or tail coverts, are longer overall. The smallest passerine is the short-tailed pygmy tyrant, at and .

Clegg et al. (2008). The bird has been used as a model to investigate the hypothesis that passerines on islands have a tendency to evolve larger forms. The lectotype is an unsexed specimen from North West Island, held by the American Museum of Natural History (AMNH 700956).Australian Faunal Directory.

Jaegers are often seen flying through the gull and (in fall) tern flocks. Ancient murrelets can be seen offshore in November – this is one of the best sites in Washington for this species. Along the sandy beaches, shorebirds can be seen. The marsh attracts a variety of passerines, particularly in migration.

Bulbuls are short-necked slender passerines. The tails are long and the wings short and rounded. In almost all species the bill is slightly elongated and slightly hooked at the end. They vary in length from 13 cm for the tiny greenbul to 29 cm in the straw-headed bulbul.
|
|
They primarily nest in areas that are centrally located to riparian vegetation and rivers. Unlike other southern passerines that lay small clutches, crimson finches have extremely large clutch sizes. This deviance could be explained by high rates of nest predation by reptiles, which use their olfactory sense to find nests.
|
|
Bahama swallows nest in old West Indian woodpecker holes in Caribbean Pine (Pinus caribaea var. bahamensis), using pine needles, Casuarina twigs, and grass to make the nest, and they line it with feathers from other passerines. They typically lay three eggs. Incubation is 15 days and the fledging period is roughly 22 days.

Sibley and Ahlquist's DNA-DNA hybridisation studies placed the robins in a Corvida parvorder comprising many tropical and Australian passerines, including pardalotes, fairy-wrens, honeyeaters, and crows. However, subsequent molecular research (and current consensus) places the robins as a very early offshoot of the Passerida, or "advanced" songbirds, within the songbird lineage.

Another species even more recently found to be distinct from tawny owls is the little-known Himalayan owl (Strix nivicolum).Del Hoyo, J., Collar, N. J., Christie, D. A., Elliott, A., & Fishpool, L. D. C. (2014). HBW and BirdLife International Illustrated Checklist of the Birds of the World: non-passerines (Vol. 1).

Measures given here are along the diagonal. Small passerines are typically captured with 30–38 mm mesh, while larger birds, like hawks and ducks, are captured using mesh sizes of ~127 mm. Net dimensions can vary widely depending on the proposed use. Net height for avian mist netting is typically 1.2 - 2.6 m.

Their movement patterns are not well resolved. Generally it seems to be sedentary, but there is a seasonal influx of Chilean hawks to NW Argentina. Perhaps they follow the swarms of migrant passerines or even Chilean pigeons (Columba araucana). It has been recorded as breeding in Magallanes Province but migrating away afterwards.
|
|
Instead, after a 21-day incubation, the ducklings fledge and after a few hours are completely independent, leaving their broodmates and fending for themselves. In contrast with the brood parasitic passerines, whose young are altricial, black-headed duck ducklings are precocial. The black-headed duck is not considered threatened by the IUCN.

Sibley and Ahlquist's DNA-DNA hybridisation studies placed this group in a Corvida parvorder comprising many tropical and Australian passerines, including pardalotes, fairy-wrens, honeyeaters, and crows. However, subsequent molecular research (and current consensus) places the robins as a very early offshoot of the Passerida (or "advanced" songbirds), within the songbird lineage.

Pterocliformes (sandgrouse), Columbiformes (pigeons), Cuculiformes (cuckoos), Caprimulgiformes (nightjars), and Apodiformes (swifts, hummingbirds) are no longer recognized as near passerines. The true near-passerine families are the Psittaciformes (parrots), the Falconiformes (falcons), and the Cariamiformes (seriemas). These three orders, together with the Passeriformes make up the Australaves. Sister to the Australaves are the Afroaves (see Telluraves).
|
|
Both sexes feed the single chick, which is hatched covered in downy feathers. Unlike their relatives in the birds of paradise family, which feed their chicks by regurgitation, the parents feed the chick whole food that has not been swallowed. The chick takes up to 35 days to fledge, a long time for passerines.

The bill of the varied sittella is upturned. The two species of sittella are small passerines which resemble nuthatches in appearance. The wings are long and broad, and when spread have clearly fingered tips. The family has a generally weak flight, which may explain their inability to colonize suitable habitat on islands like Tasmania.
|
|
They prey on waterfowl, passerines, and migrating birds. Grouse are commonly hunted in their introduced range, and many instances of pheasant predation are recorded in the Ussuri territory. Raccoon dogs eat beached fish and fish trapped in small water bodies. They rarely catch fish during the spawning season, but eat many during the spring thaw.

Long-eared owls, along with migrating short-eared owls, were observed in Spain hunting night-migrating passerines that were attracted to manmade light sources.Canário, F., Leitão, A. H., & Tomé, R. (2012). Predation attempts by short-eared and long-eared owls on migrating songbirds attracted to artificial lights. Journal of Raptor Research, 46(2), 232-235.

Young birds reach a maximum weight heavier than their parents; they can cope with not being fed for long periods of time, and delay their feather growth when undernourished. Swifts and seabirds have generally secure nest sites, but their food sources are unreliable, whereas passerines are vulnerable in the nest but food is usually plentiful.
|
|
Predators such as squirrels, stoats, weasels, foxes, rats and corvids, are kept low. The estate participates in conservation and countryside stewardship schemes, including the establishment of conservation strips around arable fields, creating ‘beetle banks’ (raised ridges in fields to encourage aphid-consuming carabids) and leaving crops to overwinter in fields which to benefit passerines.
|
|
Tui are also known for their noisy, unusual call, different for each individual, that combine bellbird-like notes with clicks, cackles, timber-like creaks and groans, and wheezing sounds. Songbirds have a bifurcated sound producing organ called a syrinx. Passerines like the tui have additional muscles giving them the ability to produce complex vocalisations.

Like all Australian robins, it is not closely related to either the European robin or the American robin, but belongs rather to the Corvida parvorder, comprising many tropical and Australian passerines, including pardalotes, fairy-wrens and honeyeaters, as well as crows. Alternate common names given to the species have been large-headed robin and pale robin.

Ioras will commonly live close to humans and even lives in the suburbs of cites like Singapore. They are mostly not threatened by human activities, although the green iora is listed as near threatened by the IUCN, habitat loss being responsible for its decline. Unlike many other passerines they are not common species in the cage bird trade.

The bird genus Hirundo is a group of passerines in the family Hirundinidae (swallows and martins). The genus name is Latin for a swallow. These are the typical swallows, including the widespread barn swallow. Many of this group have blue backs, red on the face and sometimes the rump or nape, and whitish or rufous underparts.

Spotted flycatchers hunt from conspicuous perches, making sallies after passing flying insects, and often returning to the same perch. Their upright posture is characteristic. Most passerines moult their primary flight feathers in sequence beginning near the body and proceeding outwards along the wing. The spotted flycatcher is unusual in replacing the outer flight feathers before those nearer the body.

Mediterranean flycatchers hunt from conspicuous perches, making sallies after passing flying insects, and often returning to the same perch. Their upright posture is characteristic. Most passerines moult their primary flight feathers in sequence beginning near the body and proceeding outwards along the wing. The Mediterranean flycatcher is unusual in replacing the outer flight feathers before those nearer the body.

In the urban environment of Terre Haute, it was found that starlings were taken in almost the same proportion as starlings were of all birds observed by researchers (i.e. they were 60% of 2146 individual birds seen). Somewhat over 60% of the bird species known in the Cooper's hawks’ prey spectrum are passerines (including thrushes and starlings).

Recorded weights range from 0.69 to 2 kg (1.5 to 4.4 lb),Common Raven. Oiseaux-birds.com. Retrieved on 2012-12-19. thus making the common raven one of the heaviest passerines. Birds from colder regions such as the Himalayas and Greenland are generally larger with slightly larger bills, while those from warmer regions are smaller with proportionally smaller bills.
|
|
The eggs are incubated by the female only for 11 to 14 days, with the average being 13 days. Like all passerines, the chicks are altricial at hatching, mostly naked with closed eyes. The female broods the chicks during the first four days after hatching. Both parents feed the nestlings and remove fecal sacs from the nest.
|

Rare American passerines include red-eyed vireo and blackpoll warbler. Some rarities breed in Europe, but are short-distance migrants which rarely make it to Great Britain. Examples are crested lark and Marmora's warbler. Siberian species such as yellow-browed warbler and Pechora pipit also occur much more regularly in Britain than further east in Europe.

Part of the work involved collecting the albumen of eggs of wild birds, which Sibley later used in his work on the classification of passerines. Melvin Traylor described and named a subspecies Calandrella conirostris makawai after Makawa in 1962. Other subspecies named after him include Malaconotus olivaceus makawa from Malawi. Coracopsis rasa makawa from the Comoros.

Chapman and Hall, Methuen, London. Most birds, including passerines (perching birds), have their young born blind, naked and helpless (altricial), totally dependent for their survival on parental care. The young are typically raised in a nest; the parents catch food and regurgitate it for the young. Some birds such as pigeons create a "crop milk" which they similarly regurgitate.

The hunting of birds by the Ural owl seems almost entirely based on opportunity as there is little evidence that they track down birds of any particular type, just merely upon the chance of encounter or detection. Thrushes are probably taken in many parts of the range due to their relative commonality in the habitat types used by Ural owls while other passerines that are widely taken also often have similar habitat preferences such as Old World flycatchers, finches and tits. Most passerines, and indeed most identified birds overall, are in between the size of a chaffinch (Fringilla coelebs), at a mean weight of and a Eurasian jay (Garrulus glandarius), at a mean weight of . Bird prey may occasionally range down to the size of the goldcrest (Regulus regulus), which is Europe’s smallest bird species.

Like the rest of the Australasian robins, the scarlet robins are stocky passerines with large heads. They range in size from 12 to 13.5 cm in length and weigh between 12 and 14 g. The plumage is sexually dimorphic. The males have black heads, backs and tails, black and white wings, a scarlet red breast, and white belly, forehead and rump.

Traditionally, the bird order Apodiformes contained three living families: the swifts (Apodidae), the treeswifts (Hemiprocnidae), and the hummingbirds (Trochilidae). In the Sibley-Ahlquist taxonomy, this order is raised to a superorder Apodimorphae in which hummingbirds are separated as a new order, Trochiliformes. With nearly 450 species identified to date, they are the most diverse order of birds after the passerines.
|
|
The ioras are small to medium small sized passerines, ranging from in length. Overall the males are larger than the females. These are reminiscent of the bulbuls, but whereas that group tends to be drab in colouration, the ioras are more brightly coloured. The group exhibits sexual dimorphism in its plumage, with the males being brightly plumaged in yellows and greens.

Boev (1999), p. 111 Boev diagnosed it as an extinct species of the genus Regulus. The ulna is smaller than that of most passerines, and the shape of the articular surfaces identify it as a kinglet. It is distinguished from R. regulus by a thicker base, a longer olecranon, a larger cotyla dorsalis, and smaller quill knobs (papillae remigales caudales).

The cowbird and cuckoo require the nests and parental care of other passerines in order for their young to fledge. These are known as brood parasites. The parasitic bird species mimics egg patterns and colours of the host species, which reduces egg rejection.May, R. M., & Robinson, S.K. (1984) Population dynamics of avian brood parasitism. The American Naturalist 126(4):475–494.

The yellow-rumped thornbill is insectivorous; major prey items include ants, beetles, bugs and lerps. Other items eaten include spiders, flies and seeds. The species usually forages in small groups of between 3-12 individuals, and may join mixed species-flocks with other small insectivorous passerines such as the speckled warbler (Chthonicola sagittatus), weebill (Smicrornis brevirostris), and other species of thornbill.

Eopsaltria is a genus of small forest passerines known in Australia as the yellow robins. They belong to the Australasian robin family Petroicidae. The name is derived from the Ancient Greek for "dawn singer/song" because of their dawn chorus. They are inquisitive and bold birds, and have been reported perching on the shoulders or boots of people in the bush.

The Florence Lake National Wildlife Refuge, in Burleigh County, North Dakota, United States, has almost of virgin native mixed-grass prairie and a lake. This high quality prairie habitat attracts grassland birds including grassland passerines that are sought by birders visiting the region. Florence Lake National Wildlife Refuge is administered by Long Lake National Wildlife Refuge as an unstaffed satellite refuge.

The young leave the nest by 9–12 days of age and fly capably by the time they are a few weeks old. If the nesting attempt is disturbed, scarlet tanagers apparently are unable to attempt a second brood, as several other passerines can. In a study of 16 nests in Michigan, 50% were successful in producing one or more fledglings.Prescott, K.W. (1965).
|

Studies have found that the physiology of the yellow chats differs from other species of passerines with adaptations to help them cope with the challenging environment. Studies have shown that they are able to reduce their metabolic rate and evaporative water loss. The metabolic rate is mostly controlled by the concentration of thyroid hormone.Collins, K.J. and Weiner, J. S. (1968).

Moulting is annual in most species, although some may have two moults a year, and large birds of prey may moult only once every few years. Moulting patterns vary across species. In passerines, flight feathers are replaced one at a time with the innermost being the first. When the fifth of sixth primary is replaced, the outermost begin to drop.

The sequential colonization and speciation of the Chasiempis sandwichensis subspecies (denoted by the orange arrows) with their divergence times and island geological ages. Uniquely among Hawaiian passerines, the distribution of the elepaio is peculiarly discontinuous. According to fossil remains, the birds did not occur on Maui Nui or its successor islands. Their current distribution is absent from the Maui Nui island group.
|
|
However, this may not be as common as is typically thought, as only 1% of food matter in one study was bird material. Despite this, other passerines may still mob jays who come within their breeding territories. When a blue jay is agitated or angry, the blue crest atop its head will rise. It will lower when the bird is relaxed or calm.

The yellow-throated miner (Manorina flavigula) is a species of colonial honeyeater, endemic to Australia. It is also known as the white-rumped miner. The distinctive white rump is easy to observe in the field and distinguishes it from the other miner species. Yellow-throated miners are medium-sized, grey passerines with yellow throat markings, legs, and bare patches around the eye.

The seriemas are the sole living members of the small bird family Cariamidae, which is also the only surviving lineage of the order Cariamiformes. Once believed to be related to cranes, they have been placed near the falcons, parrots and passerines, as well as the extinct Phorusrhacidae.Hackett, S. J. et al. (2008) A Phylogenomic Study of Birds Reveals Their Evolutionary History.

They are placed in the genus Loxops. Only one of the species in the genus, the Hawaiʻi ʻakepa, is still extant, and is classified as Endangered by the IUCN. Previously considered conspecific, the group was split into distinct species in 2015. Found only in high elevation old growth rainforest, these nonmigratory passerines have rounded heads, black eyes, and black wings and tail.

The eremomelas are a genus, Eremomela, of passerines in the cisticola family Cisticolidae. The genus was previously placed with the larger Old World warbler family Sylviidae prior to that genus being broken up into several families. The genus contains eleven species, all of which are found in sub- Saharan Africa. They occupy a range of habitats, from arid scrub to lowland tropical forest.

Although loggerhead shrikes are passerines, they are a predatory species that hunt during the day. They primarily eat insects, but also consume arachnids, reptiles, amphibians, rodents, bats and small birds. The size of prey ranges from 0.001 g insects to 25 g mice or reptiles. They are not true birds of prey, as they lack the large, strong talons used to catch and kill prey.

The long-tailed paradise whydah or eastern paradise whydah (Vidua paradisaea) is from the family Viduidae of the order Passeriformes. They are small passerines with short, stubby bills found across Sub-Saharan Africa. They are mostly granivorous and feed on seeds that have ripen and fall on the ground. The ability to identify between males and females is quite difficult unless it is breeding season.

They also disagreed on what groups they should focus on; Ali favoured ringing passerines while Abdulali suggested that he work on waders. Humayun was of the view that the grant given by the state government for the collection should not be diverted to other projects. The disagreement led to Humayun not being nominated to the executive committee in the 1971 elections of the Societysss .

Black-chested prinias have a complete biannual molt, meaning they undergo a complete molt (including flight feathers) twice a year. This species’ spring molt (September-November) is a short one of approximately 10 weeks. The autumn molt (February-June, with 95% of adults molting in April) is a longer one of approximately 15 weeks. A complete biannual molt like this one is quite rare in passerines.

The family Hirundinidae was introduced (as Hirundia) by the French polymath Constantine Samuel Rafinesque in 1815. The Hirundinidae are morphologically unique within the passerines, with molecular evidence placing them as a distinctive lineage within the Sylvioidea (Old World warblers and relatives). They have also been linked to the white-eyes and the tits. Under the Sibley-Ahlquist taxonomy, they have been placed in the infraorder Passerida.

Yellow-tufted honeyeaters are a noisy, active species in colonies from a few up to a hundred. It aggressively defends territories around flowering trees. It has a great variety of calls from a warbled "tui-t-tui-t-tui", a whistled "wheit-wheit", a sharp "querk" to a harsh contact-call "yip" or "chop-chop".Slater, Peter (1974) A Field Guide to Australian Birds: Passerines.

Synchronous provisioning increases brood survival in cooperatively breeding pied babblers. Journal of Animal Ecology, 79(1), 44-52. White-eyes are among the more frequently taken smaller passerines, with the African yellow white-eye (Zosterops senegalensis) being the smallest identified avian prey species, although penduline tits (Anthoscopus ssp.) (thus far unidentified to species) are likely to be even smaller.Bubo lacteus (Verreaux's eagle-owl, Giant eagle owl) . Biodiversityexplorer.org.

The mistletoebird is a geologically recent arrival into Australia from South-East Asia. It is thought to have started colonizing Australia from about two million years ago. The mistletoebird is a mistletoe- feeding specialist and mistletoe-feeding specialists have evolved independently in eight of the world's avian families. This extreme dietary specialization has evolved in non-passerine species, as well as sub-oscine and oscine passerines.

When attacking large prey, it leaps upon the animal's back, and attempts to bite the neck or carotid. It does not persist in attacking if prey manages to escape. The European wildcat primarily preys on small mammals such as rabbit (Oryctolagus cuniculus) and rodents. It also preys on dormice, hares, nutria (Myocastor coypus) and birds, especially ducks and other waterfowl, galliformes, pigeons and passerines.
|

Many passerines seek out taurine-rich spiders to feed their young, particularly just after hatching. Researchers compared the behaviours and development of birds fed a taurine-supplemented diet to a control diet and found the juveniles fed taurine-rich diets as neonates were much larger risk takers and more adept at spatial learning tasks. Taurine has been used in some cryopreservation mixes for animal artificial insemination.

Stackpole Company, Harrisburg, PA, USA. Sometimes other similar rodents like voles can also be found frequently in the snowy owl's foods. It is R-selected, meaning that it is an opportunistic breeder capable of taking advantage of increases in prey numbers and diversity, despite its apparent specialization. Birds are commonly taken as well, and may regularly include passerines, northern seabirds, ptarmigan and ducks, among others.

The masked shrike feeds mainly on large insects, although other arthropods and small vertebrates are also caught. Shrikes fatten up before migration, but to a lesser extent than other passerines because they can feed on the way, sometimes taking other tired migrants.Lefranc & Worfolk (1997) p. 20. Despite its relatively small size, the masked shrike has been recorded as killing species such as lesser whitethroat and little swift.

The Chilean hawk's food is almost exclusively birds (97.8% of all prey remains in one study),Figueroa Rojas et al. (2004) in particular a diverse selection of forest passerines. More than 30 bird species are documented to be eaten by this hawk at least occasionally. Rodents of at least 4 species and every now and then an occasional insect or squamate round off its diet.

In its natural habitat, the warbling white-eye competes with other native passerine bird species, including those of the same genus, such as the Bonin white-eye (Apalopteron familiare). In Hawaii, the warbling white-eye competes with native passerines such as the common 'amakihi, for food (such as nectar and fruit), as well as for space.Gibson L. (2000) Rules and Regulations. Federal Register, 65(75): 20760-20769.

Other species deposit the sacs on the rim of the nest, where they are likely to be seen (and removed) by parent birds. Not all species generate fecal sacs. They are most prevalent in passerines and their near relatives, which have young that remain in the nest for longer periods. In some species, the fecal sacs of small nestlings are eaten by their parents.

Petrochelidon pyrrhonota 1894 The American cliff swallow belongs to the largest order and dominant avian group – Passeriformes. They are the perching birds, or the passerines. All the bird species in this order have 4 toes, 3 pointing forward and one pointing backwards, that enable them to perch with ease. The sub-order that the American cliff swallow belongs is Oscines (or Passeri), for the songbirds.
|

They were also called peacock-wrens and Australian birds-of- paradise. The idea that they were related to the pheasants was abandoned when the first chicks, which are altricial, were described. They were not classed with the passerines until a paper was published in 1840, 12 years after they were assigned a discrete family, Menuridae. Within that family they compose a single genus, Menura.

These small passerines are found in rank grassland habitats, often near swamps or water. Male cisticolas are polygamous; the female builds a discreet nest deep in the grasses, often binding living leaves into the soft fabric of felted plant-down, cobwebs, and grass. The croaking cisticola's nest is a ball shape with a side entrance; 2-4 eggs are laid. This is the largest cisticola.

Cinnycerthia is a genus of bird in the wren family, Troglodytidae. It contains four species which inhabit the undergrowth of montane forests in the Andes.Ridgely, Robert S. and Guy Tudor (1994) The Birds of South America, volume 2: the Suboscine Passerines, University of Texas Press. None of them are considered to be threatened with extinction and they are classified as species of Least Concern by BirdLife International.

Falco peregrinus is included in Appendix I of CITES. Globally, 96% of the birds with distribution in the Reserve are classified by the IUCN as minor concern and four almost threatened (M. ocellata, E. nana, Melanoptila glabirostris and P. ciris). 71% of the birds (114 species) present in the Reserve are residents of the region, highlighting the order of the passerines with 57 species.
|
|
The musculature around the proboscis (the proboscis receptacle and receptacle protrusor) is also structured differently in this order. This genus contains six species that are distributed globally, being collected sporadically in Hawaii, Europe, North America, South America, and Asia. These worms exclusively parasitize birds by attaching themselves around the cloaca using their hook-covered proboscis. The bird hosts are of different orders, including owls, waders, and passerines.

The kōkako appears to be a remnant of an early expansion of passerines in New Zealand and is one of five species of New Zealand wattlebirds of the family Callaeidae, the others being two species of endangered tieke, or saddleback, and the extinct huia. New Zealand wattlebirds have no close relatives apart from the stitchbird, and their taxonomic relationships to other birds remain to be determined.

Corvids are the largest passerines. Corvids display remarkable intelligence for animals of their size and are among the most intelligent birds thus far studied. Specifically, members of the family have demonstrated self-awareness in mirror tests (European magpies) and tool-making ability (e.g. crows and rooks), skills which until recently were thought to be possessed only by humans and a few other higher mammals.

The altricial nestlings hatch naked, blind and pink-skinned, weighing c. ; their skin turns darker after a few days. The inside of their beak is pink and they probably lack spots or other prominent marks; the wattles at the corners of the mouth are yellow as in many passerines. As the nestlings grow, the female broods them, and later on assists in providing food.

The bird has a buff throat, buff spots on the crown and breast, fine buff streaks on the back and a black moustachial stripe.Ridgely, Robert S. & Guy Tudor (1994) The Birds of South America, volume 2: the Suboscine Passerines, University of Texas Press. The song is a descending series of staccato notes. It calls include a short descending whistle, a quavering liquid call and a dry rattle.

The nest is built by the female while the male guards. The typical clutch is three eggs, which both parents incubate and both feed the young, which hatch after about 12 days. The webs of large spiders such as Nephila maculata have been known to trap the bird. An astrovirus was detected in a black-naped monarch in Cambodia, a virus that was earlier unknown from passerines.

It is an important breeding area for the endangered wood stork and other wetland birds. It also has wintering passerines, including the painted bunting. Numerous wading bird species can be found in the wetlands of the sanctuary, including the yellow-crowned night heron, black-crowned night heron, tricolored heron, great egret, and snowy egret. Specialist birds include limpkin, barred owl and, in summer, swallow- tailed kite.

The natural habitat of various types of animals varies within the country. Some species only populate special restricted areas (lakes, parts of mountainous areas) while others are spread throughout the country. For example, passerines can be found anywhere in the territory of Azerbaijan. Protozoa parasites are also registered in all areas of the country, depending on natural habitat of carrier animals such as cattle and poultry.

Known as a syconium, the fruit is an inverted inflorescence with the flowers lining an internal cavity. Ficus obliqua is pollinated by two species of fig wasp—Pleistodontes greenwoodi and P. xanthocephalus. Many species of bird, including pigeons, parrots and various passerines, eat the fruit. The range is along the east coast from Queensland, through New South Wales in rainforest, savanna woodland, sclerophyll forest and gallery forest.
|
|
As in all passerines, the chicks are born naked, and blind (altricial), and remain in the nest for an extended period (nidicolous). Both parents feed the young, but the male feeds them alone after leaving the nest and as they become more independent, and also moves from giving food directly to them to placing it on the ground near them so they learn to eat for themselves.

Like all accipiters, the tiny hawk feeds primarily on birds. It hunts hummingbirds and small passerines, typically darting out from a place of concealment to snatch them as they pass by, but also ambushing them when the smaller birds are perched. There is some evidence that it learns the regular perches of some hummingbirds and hunts for them there. Some individuals also hunt rodents.

Common starling (Sturnus vulgaris) has iridescent plumage Starlings are medium-sized passerines. The shortest-bodied species is Kenrick's starling (Poeoptera kenricki), at , but the lightest- weight species is Abbott's starling (Poeoptera femoralis), which is . The largest starling, going on standard measurements and perhaps weight, is the Nias hill myna (Gracula robusta). This species can measure up to and, in domestication they can weigh up to .

Psittacopes is an extinct genus of bird from Middle Eocene. One species is recorded from Messel, Germany (P. lepidus), and other three possible unnamed species are from London Clay, England. Its phylogenetic placement within Aves is uncertain; it was originally interpreted as a parrot, but the phylogenetic analysis conducted by Mayr (2015) recovered it as more closely related to the passerines and the extinct family Zygodactylidae.

Ornithol. Anz. 44: 117-122. Unlike smaller passerines, corvids roost in numbers in relatively open spots, which make them fairly vulnerable to a predator as stealthy and powerful as the eagle-owl.Penteriani, V., Sergio, F., del Mar Delgado, M., Gallardo, M., & Ferrer, M.

The red-ruffed fruitcrow (Pyroderus scutatus) is a species of bird in the monotypic genus Pyroderus. It belongs to the family Cotingidae, and is one of the largest passerines in South America. Its common names in Spanish include yacutoro, toropisco montañero, sangretoro, pájaro torero, and cuervo-frutero de garganta roja. This species was first named Coracias scutata by Shaw in 1792, but was later changed to the current scientific name.

While she is on the nest, the male provisions her with food. The young, which like all passerines hatch almost naked and helpless, take another 15–19 days or so to fledge. They are being fed by both parents, and need plenty of food given their tiny size (see also Bergmann's Rule). As the young near fledging, the parents spend much of their time procuring food for them.

This woodswallow's soft-plumage is charcoal grey apart from the white underparts that give the species its English and scientific names, in contrast to the related great woodswallow whose upperside is a more glossy black.Coates, Brian J.; The Birds of Papua New Guinea Including the Bismarck Archipelago and Bougainville: Volume 2 - Passerines; pp. 373-375. Despite its brush-tipped tongue, usually associated with nectar feeders, it catches insects on the wing.

It has a brownish-red nape, a grey-brown back and pale cinnamon underparts. The dark tail is tipped with white laterally. Females are smaller with olive-grey crown, similar in colouring to male but slightly duller; and juveniles are pale warm cinnamon below with grey to olive-brown upperparts, a brown-red eye and orange base to the bill.Slater, Peter (1974) A Field Guide to Australian Birds: Passerines.

In the May of the fourth year after infection, the shoots start to produce flower bud full flowering and pollination occurring in November and December. (Hummingbirds and passerines are thought to be the pollinators.) Fruit maturation takes about a year and occurs from November to February of the fifth year. The long life cycle means that infestations may be relatively easily controlled when trees are to be harvested for forestry.

Historically, there has been far more research on the mimetic abilities of male lyrebirds. This is primarily due to the assumption that the evolution of song in passerines resulted primarily from the selection on males in attracting mates or deterring rivals. However, a study found that females also produced mimetic vocalisations while foraging and during nest defence, suggesting that mimicry has a function in deterring predators and conspecific rivals.

Albatrosses (black-browed, Chatham, yellow-nosed, etc.) are occasionally spotted off the cliffs as are short-tailed shearwaters (particularly during their spring migration), black-faced and pied cormorants, kelp gulls and Australasian gannets. The shrubs decorating the area are frequently home to brown thornbills, singing honeyeaters and a number of other passerines. The elusive striated fieldwren has also been known to inhabit the area. Some flora include cushion bushes.

Blackburnian warblers are solitary during winter and highly territorial on their breeding grounds and do not mix with other passerine species outside of the migratory period. However, during migration, they often join local mixed foraging flocks of species such as chickadees, kinglets and nuthatches. Similarly, in the tropics they were found to be fairly social while engaging in migration but solitary from other passerines while wintering.Bent, A. C. 1953.

The coast and offshore islands are home to gulls, terns and cormorants. The mountainous north of the country attracts many passerines in passage, the desert areas are home to the endangered houbara bustard, sand partridge, four species of sandgrouse, desert larks, pipits, wheatears and buntings. The mountains additionally attract golden eagles and Egyptian vultures. The Dhofar region in the south has a great variety of breeding and migratory species.

Nests are typical of many passerines in both construct, material and size, made from leaves, twigs, rootlets or hair.Baicich, P. J., and C. J. O. Harrison. 1997. A guide to the nests, eggs, and nestlings of North American birds. 2nd ed. Academic Press, San Diego, CA. Clutches are from 1 to 5 eggs, normally being 3–4, being pale blue to green with purplish to brownish red spotting.

The plushcap (Catamblyrhynchus diadema) is a species of bird in the tanager family Thraupidae and it is the only member of the genus Catamblyrhynchus. The plushcap is one of the most distinctive of all Neotropical passerines in both its appearance and behavior. The plushcap (Catamblyrhynchus diadema) was in its own family until recently when it was grouped with the tanagers. It is very distinct both physically and in its behavior.

Eufalconimorphae is a proposed clade of birds, consisting of passerines, parrots, falcons, caracaras, and forest falcons (but not other raptors). It has whole-genome DNA support. The Eufalconimorphae is noted to produce aerodynamic force during the upstroke of the flight, this is supposed to help create a vertical flight pattern.Razmadze, Daria, et al. “Anatomy of the Forelimb Musculature and Ligaments of Psittacus Erithacus (Aves: Psittaciformes).” Journal of Anatomy, vol.

In some passerines, filoplumes arise exposed beyond the pennaceous feathers on the neck. The remiges, or flight feathers of the wing, and rectrices, or flight feathers of the tail, are the most important feathers for flight. A typical vaned feather features a main shaft, called the rachis. Fused to the rachis are a series of branches, or barbs; the barbs themselves are also branched and form the barbules.
|
|
A further species with multiple bird hosts is C. borealis, found in the nests of passerines and cliff-nesting sea birds. C. borealis has been known to hybridise with C. gallinae. C. gallinae is most prevalent in birds with nests in nest-holes and crevices. Infestations of nests in nest-holes and crevices are also more intense, meaning that there are more wintering C. gallinae in those nests.

This minor planet was named after bird genus Hirundo, a group of passerines in the family Hirundinidae (swallows and martins). "Hirundo" is Latin word for swallow. They are found all over the world with the exception of New Zealand and the polar regions. Known for their graceful flight and regular migrations, swallows feature a short bill with a wide gape, small weak feet, and typically a deeply forked tail.

The chestnut owlet occurs in humid lowland rainforest and montane forest, at in altitude. The biology of the chestnut owlet is little known but like the related African barred owlet it is partly diurnal. Like other owls it will be mobbed by small passerines if discovered at its roost. Its prey is small vertebrates and arthropods, which are either caught from a perch or gleaned from the foliage.

Wagtails, pipits, and longclaws are slender, small to medium-sized passerines, ranging from 14 to 17 centimetres in length, with short necks and long tails. They have long, pale legs with long toes and claws, particularly the hind toe which can be up to 4 cm in length in some longclaws. There is no sexual dimorphism in size. Overall the robust longclaws are larger than the pipits and wagtails.

Birds were the main foods for wintering long-eared owls in Romania's Danube delta, with birds making up 59.5% of total prey by number and 51.6% by biomass of 948 prey items against 40.7% by number and 48.4% by biomass for mammals. Here, numerous passerines were mostly taken with the finch family (18.6%), Old World sparrow family (15.7%) and the tit family (12.7%) being the commonest prey families among the birds.

A pair can raise up to three broods per year, frequently reusing and relining the same nest, although two broods is typical, or just one north of 48°N. Within two months, most juveniles will have moulted and gained their first basic plumage. They acquire their adult plumage the following year. As with other passerines, the nest is kept clean and the chicks' faecal sacs are removed by the adults.
|
|
Small to mid-sized birds, i.e. passerines, woodpeckers, waterfowl, pigeons, and gamebirds, are most often taken. However, since the adults of most smaller birds can successfully outmaneuver and evade buteos in flight, much avian prey is taken in the nestling or fledgling stages or adult birds if they are previously injured. An exception is the short-tailed hawk, which is a relatively small and agile species and is locally a small bird-hunting specialist.

The nests of malkohas and Asian ground cuckoos are shallow platforms of twigs, but those of coucals are globular or domed nests of grasses. The New World cuckoos build saucers or bowls in the case of the New World ground cuckoos. Non-parasitic cuckoos, like most other non-passerines, lay white eggs, but many of the parasitic species lay coloured eggs to match those of their passerine hosts. The young of all species are altricial.

The nasal opening is small and circular Woodswallows are smooth, agile flyers with moderately large, semi-triangular wings. They are among the very few passerines birds that soar, and can often be seen feeding just above the treetops. One sedentary species aside, they are nomads, following the best conditions for flying insects, and often roosting in large flocks. Although woodswallows have a brush-tipped tongue they seldom use it for gathering nectar.

These features indicate that the long-legged bunting was a ground dweller and likely flightless. This makes it one of the few known flightless passerines known, the others being three species of New Zealand wrens: Lyall's wren (Traversia lyalli), the long-billed wren (Dendroscansor decurvirostris) and the stout-legged wren (Pachyplichas yaldwyni). All three of these wrens are also extinct. This bunting was probably omnivorous, like the other species in its genus.

Because of the Gulf Stream, Scilly has a particularly mild climate - residents can grow sub- tropical plants there. Scilly is the first landing for many migrant birds, including extreme rarities from North America and Siberia. Scilly is situated far into the Atlantic Ocean, so many North American vagrant birds will make first European landfall in the archipelago. Scilly is responsible for many firsts for Britain, and is particularly good at producing vagrant American passerines.

Woodpecker vocalisation is thought to be genetically hardwired; different to passerines that learn song. Each Celeus species has different song types, with structure and note compositions highly simplistic. Most species are highly vocal, an exception being C. galeatus which is silent when not in breeding season. Calls range from low to loud whistling of the C. grammicus, high pitched laughing of the C. flavus, to parrot like screeches of the C. elegans.

Their song is more varied and complex than that of the scarlet robin, and has been described as the most musical of the red robins. A series of descending notes in groups of three, the musical song has been likened to the phrases, "you-may-come, if- you-will, to-the-sea"Slater, Peter (1974) A Field Guide to Australian Birds: Passerines. Adelaide: Rigby. or "you-are-not a-pretty-little-bird like-me".

Kelp in the sea next to the machair softens the impact of waves, reducing erosion, and when it is washed ashore by storms, forms a protective barrier on the beach. As it rots, the sand flies it abounds in provide rich feeding for flocks of starlings and other passerines, wintering waders, gulls and others. If covered with sand, it will compost to form a fertile bed where annual coastal flowers and marram grass will thrive.

Many small birds have having a low aspect ratio with elliptical character (when spread), allowing for tight maneuvering in confined spaces such as might be found in dense vegetation. As such they are common in forest raptors (such as Accipiter hawks), and many passerines, particularly non- migratory ones (migratory species have longer wings). They are also common in species that use a rapid take off to evade predators, such as pheasants and partridges.

List of Recent Holarctic Bird Species is a 1977 book by Karel H. Voous, published by the British Ornithologists' Union. It contains a list of 1,921 bird species recorded from the Holarctic zoogeographic region. It was widely adopted by ornithologists in Europe as a standard baseline list. It was originally published in two parts in the BOU's journal Ibis: that covering the non-passerines in 1973, and the passerine part in 1977.

At , Lake Ovid is the largest body of water in the surrounding area. The lake's fish species include catfish, black crappie, largemouth bass, muskellunge, sunfish, yellow perch, and other freshwater species — bluegill, northern pike, bowfin, brown bullhead, carp, white sucker, pumpkinseed, and yellow bullhead. The lake is stocked with muskellunge and channel catfish. Migrating waterfowl, shorebirds and passerines are drawn to Lake Ovid, and more than 228 bird species have been recorded in the park.

The young are subsequently fed largely with fruit. The chicks fledge about 14–16 days after hatching. They are fed by the adults for about two weeks after fledging. Breeding densities of this waxwing are typically low compared to other passerines, usually less than ten birds per square kilometre (26 per square mile) even in good habitat, although up to 35·6 birds per square kilometre (92 per square mile) have been found in Russia.

The delta has been protected since the early 1900s, with one of the first Russian nature preserves (Astrakhan Nature Reserve) having been set up there in 1919. Much of its local fauna is considered endangered. The delta is a major staging area for many species of water birds, raptors and passerines. Although the delta is best known for its sturgeons, catfish and carp are also found in large numbers in the delta region.

Telluraves (also called land birds or core landbirds) is a recently defined clade of birds with controversial content. Based on most recent genetic studies, the clade unites a variety of bird groups, including the australavians (passerines, parrots, seriamas, and falcons) as well as the afroavians (including the Accipitrimorphae – eagles, hawks, buzzards, vultures etc. – owls and woodpeckers, among others). They appear to be the sister group of a newly defined clade centered on Aequornithes.

In all four of the passerine species that were observed, the more common morph of the artificial prey were consumed more frequently. regardless of the color of it. This study also had a second component in which they allowed the birds to become familiar with one color of the prey, and then presented the dimorphic prey in equal amounts. In this case, the passerines consumed more of the prey that they were accustomed too.

Many Italian studies reflect relatively high numbers of birds being hunted, mainly in the non- breeding times. One of the smaller large representations was at Prignano Cilento where 13.85% were made up of mostly unidentified birds. In Regional Park of Decima-Malafede, birds were 31.1% of the diet, 13.7% of which were unidentified passerines, while European goldfinches and European greenfinch accounted for a further 7.1% and 4.6% of the prey items.Trotta, M. (2010).

Kinglets are among the least of all passerines, ranging in size from and weighing ; the sexes are the same size. They have medium-length wings and tails, and small needle-like bills. The plumage is overall grey-green, offset by pale wingbars, and the tail tip is incised. Five species have a single stiff feather covering the nostrils, but in the ruby-crowned kinglet this is replaced by several short, stiff bristles.

The bluebirds are a group of medium-sized, mostly insectivorous or omnivorous birds in the order of Passerines in the genus Sialia of the thrush family (Turdidae). Bluebirds are one of the few thrush genera in the Americas. They have blue, or blue and rose beige, plumage. Female birds are less brightly colored than males, although color patterns are similar and there is no noticeable difference in size between the two birds.

According to David Lack, the earliest recorded use of radar in detecting birds came in 1940. The movements of gulls, herons and lapwings that caused some of the detentions was visually confirmed. It was however only in the 1950s through the work of Ernst Sutter at Zurich airport that more elusive "angels" were confirmed to be caused by small passerines. David Lack was one of the pioneers of radar ornithology in England.

Scaly foot, otherwise known as knemidocoptiasis, is caused by burrowing mites in the genus Knemidocoptes. The condition can be compared with sarcoptic mange in mammals, but does not seem to cause the same level of itching. The birds chiefly affected are galliformes (chickens and turkeys), passerines (finches, canaries, sparrows, robins, wrens), and psittacine birds (parrots, macaws, parakeets, budgerigars). The condition sometimes additionally affects piciformes (woodpeckers, toucans) and anseriformes (ducks, geese, swans), raptors and other birds.

In this tract, birders can spot a variety of passerines, raptors, colonial birds roosting in the sparse chenier habitat, and wading birds. The second largest stretch of forest is a combination of the Maples tract and the Landry-Leblanc tract. Because of its in the vicinity of a local grocery store, it is locally named the Sureway Woods. Together, the Maples tract and the Landry-LeBlanc tract comprise twenty acres of chenier forest.

The systematics of Old World babblers have long been contested. During much of the 20th century, the family was used as a "wastebin taxon" for numerous hard-to-place Old World songbirds (such as Picathartidae or the wrentit). Ernst Hartert was only half- joking when in 1910 he summarized this attitude with the statement that, in the passerines: "Was man nicht unterbringen kann, sieht man als Timalien an." (What one can't place systematically is considered an Old World babbler).

A diversity of small passerines has been found in the diet, especially fledgling-age larks of various species, most frequently perhaps in Kazakhstan and Mongolia. A few reptiles found in the diet around nest have included at least sand lizard (Lacerta agilis), Caspian whipsnake (Dolichophis caspius) and steppe viper (Vipera ursinii). Larger prey such as gray marmots are infrequently targeted by steppe eagles. On occasion, during summer, a steppe eagle may be able to take exceptionally large prey.

European pine vole (Microtus subterraneus), a typical common kestrel prey since prehistoric times 125px Common kestrels eat almost exclusively mouse-sized mammals. Voles, shrews and true mice supply up to three-quarters or more of the biomass most individuals ingest. On oceanic islands (where mammals are often scarce), small birds (mainly passerines) may make up the bulk of its diet. Elsewhere, birds are only an important food during a few weeks each summer when inexperienced fledglings abound.

Grallina is a genus of passerine bird native to Australia and New Guinea. It is a member of a group of birds termed monarch flycatchers. This group is considered either as a subfamily Monarchinae, together with the fantails as part of the drongo family Dicruridae, or as a family Monarchidae in its own right. More broadly, they belong to the Corvida parvorder comprising many tropical and Australian passerines including pardalotes, fairy-wrens and honeyeaters as well as crows.

The blue pitta is sexually dimorphic, the bright plumage of this bird means it is a male The pittas are small to medium-sized passerines, ranging in size from the blue-banded pitta at to the giant pitta, which can be up to in length. In weight they range from . Pittas are stout- bodied birds with long, strong tarsi (lower leg bones) and long feet. The colour of the legs and feet can vary dramatically even within a species.
|

They have a keen sense of smell, and it has been suggested that they are able to locate earthworms this way. This suggestion was supported by a study which found that the Indian pitta has the largest olfactory bulb of 25 passerines examined. Eight species have been recorded using stones as anvils on which to smash open snails to eat, and the rainbow pitta has been observed using the root of a tree to do so.

Snowy owls have been known to capture night-migrating passerines and shorebirds, sometimes perhaps on the wing, as well as large and/or potentially dangerous birds that were caught in air by snowy owls during daylight. On the wing pursuits against other various other carnivorous birds are sometimes undertaken as well to kleptoparasitize the prey caught by the other birds.Duffy, D. C., Beehler B. & Haas, W. (1976). Snowy Owl steals prey from Marsh Hawk. Auk 93 (4): 839–840.

Similar trends have been documented in various species of migrating passerines. Phenological mismatch can be curbed by phenotypic plasticity and there is debate as to the amount of impact that climate change has on phenological mismatch. Climate change has led to a shift in the timing of spring migrations over the past 50 years. There was a widespread lengthening of migrations with the earliest individuals migrating earlier and the latest migrating at a similar time or later than before.

Some species populate special restricted areas (lakes, parts of mountainous areas) while others are spread throughout the country. For example, passerines can be found anywhere in the territory of Azerbaijan. Protozoa parasites are also registered in all areas of the country, depending on natural habitat of carrier animals (cattle, poultry, etc.). Among mammals, jeyran gazelles populate plain areas, Caucasian goat inhabits the major Caucasus areas, most species of birds can be found in forests, some in water basins.

Wind turbines kill thousands of birds through collisions, disruption of migratory routes and destruction of habitat. Birds such as raptors (eagles, vultures), waterbirds and passerines are particularly affected. The reasons these birds are affected is because many of them have blind spots and they often cannot see objects (wind farms) directly in front of them. In Altamont Pass Wind Farm, 4000 wind turbines kill 75 golden eagles and over 1, 200 other predatory birds each year.

35, 170-/181. Many of the current stopover sites are threatened due increased urbanization, agriculture, gas exploitation, fisheries, tourism and many others anthropogenic activities. In one study the researchers found that birds with high phenotypic plasticity can adapt their behavior and skip low-quality stopover sites. Migratory birds such as swans, geese and waders show high site fidelity (they are loyal to their stopover and cannot change them), while long distance passerines have much lower site fidelity.

The shrikes are a family of slender, long-tailed passerines, most of its members being in the genus Lanius, the typical shrikes. They are short-necked birds with rounded wings and a hooked tip to the bill. Most occur in open habitats. The affiliations of the masked shrike with other members of the genus are uncertain; the "brown" shrikes (brown, red-backed and isabelline shrikes) and tropical species like the Somali fiscal have both been suggested as possible relatives.

Relaxation of these muscles causes inhalation. Three distinct sets of organs perform respiration — the anterior air sacs (interclavicular, cervicals, and anterior thoracics), the lungs, and the posterior air sacs (posterior thoracics and abdominals). Typically there are nine air sacs within the system; however, that number can range between seven and twelve, depending on the species of bird. Passerines possess seven air sacs, as the clavicular air sacs may interconnect or be fused with the anterior thoracic sacs.

It is not closely related to either true Old World Warblers or the New World Warblers, but belongs rather to the Corvida parvorder comprising many tropical and Australian passerines, as well as crows. The brown gerygone is similar to both the large-billed, G. magnirostris, and mangrove, G. levigaster, gerygones. It differs from the former by having a distinctive white eyebrow and a grey-tinged face.

Many other species, including parrots, corvids, and a range of passerines, have been noted as tool users. New Caledonian crows have been observed in the wild using sticks with their beaks to extract insects from logs. While young birds in the wild normally learn this technique from elders, a laboratory crow named Betty improvised a hooked tool from a wire with no prior experience, the only known species other than humans to do so.Crow making tools, news.nationalgeographic.

Prey species can include small mammals, amphibians, reptiles, fish, crabs, insects, their larvae, earthworms, shellfish and young birds. Bird species that are culled can range from large, colonial nesting birds such as storks and herons to small passerines. Reptiles taken often including snakes, lizards and small freshwater turtles as well as young American alligators. This species, along with other caracaras, is one of few raptors that hunts on foot, often turning over branches and cow dung to reach food.

The clutch generally numbers two or rarely three buff, pale yellow or pearl-grey eggs that are irregularly marked with red-brown and are 18–22 mm long by 15–16 mm wide. The eggs are more elongated than those of the eastern yellow robin. Like all passerines, the chicks are altricial; that is, they are born blind and naked. They are fed by both parents and helpers, and the female leaves to forage for herself during this period.
|
|
Other mammals preyed on occasionally include shrews, squirrels (largely chipmunks and red squirrels), various other mice species, flying squirrels, moles and bats. Also supplementing the diet are small birds, with passerines such as swallows, sparrows, kinglets and chickadees favored. However, larger birds, up to the size of rock pigeon (which are typically about 4 times as heavy as a saw-whet owl) can even be taken. On the Pacific coast they may also eat crustaceans, frogs and aquatic insects.

Western magpie female (note scalloped back) collecting nesting material The Australian magpie produces a clutch of two to five light blue or greenish eggs, which are oval in shape and about .Kaplan, p. 64. The chicks hatch synchronously around 20 days after incubation begins; like all passerines, the chicks are altricial—they are born pink, naked, and blind with large feet, a short broad beak and a bright red throat. Their eyes are fully open at around 10 days.

2005) A golden-chevroned tanager was once observed to dominate over a cherry- throated tanager individual, and a black-necked aracari was seen to attack the species for purposes unknown. There exists an observation of an apparent intraspecific threat pose, in which the head and neck are extended and held horizontally, and the wings are half-spread.(Venturini et al. 2005) Longevity is unknown, but not presumed to differ from roughly one decade common among mid-sized passerines.

In these cases the predator need not move about foraging for prey, but may simply stay still and allow prey to come to it. Some studies suggest that the northern shrike (Lanius excubitor) sings in winter often imitating small passerines that may be preyed upon when lured within reach. There has been one report of a margay using mimicry of the cry of an infant pied tamarin to try to lure an adult tamarin within striking distance.

Their total brain-to- body mass ratio is equal to that of non-human great apes and cetaceans, and only slightly lower than that of humans.Birding in India and South Asia: Corvidae. Retrieved 2007-NOV-10 They are medium to large in size, with strong feet and bills, rictal bristles, and a single moult each year (most passerines moult twice). Corvids are found worldwide except for the tip of South America and the polar ice caps.

The passerines of Australia, also known as songbirds or perching birds, include wrens, the magpie group, thornbills, corvids, pardalotes, lyrebirds. Predominant bird species in the country include the Australian magpie, Australian raven, the pied currawong, crested pigeons and the laughing kookaburra. The koala, emu, platypus and kangaroo are national animals of Australia, and the Tasmanian devil is also one of the well-known animals in the country. The goanna is a predatory lizard native to the Australian mainland.

Of the 75 species of reptiles and amphibians living in the peninsula of Spain and on the islands, 27 are present in Os Ancares. They are triturus (3 species), frog (6 species), lizards (Lacerta), vipers and snakes (6 species). Among birds, passerines are important for good representation, followed by accipitrines, among which are the short-toed eagle, the goshawk, abundant hawks, buzzards and the hen harrier. There is no shortage of red and gray partridge or grouse.

Penduline tits are tiny passerines, ranging from 7.5 to 11 cm in length, that resemble the true tits (Paridae) but have finer bills with more needle-like points. Their wings are short and rounded and their short tails are notched (except the stub-tailed tit). The penduline tits' typical plumage colors are pale grays and yellows and white, though the European penduline tit has black and chestnut markings and some species have bright yellow or red.

Notas sobre la variación estacional y geográfica de la dieta del búho chico Asio otus. Ardeola, 48(1), 75-80. The main recorded individual prey species in Beijing was the Eurasian tree sparrow, at 38% of the diet, but other avian prey was negligible here. While most of the passerines attacked by long-eared owls are well within typical prey sizes for this species, while pursuing bird prey many reports note that unusually large prey may be attacked.

Like all figs, it has an obligate mutualism with fig wasps; figs are pollinated only by fig wasps, and fig wasps can reproduce only in fig flowers. Many species of bird, including pigeons, parrots and various passerines, eat the fruit. Ficus macrophylla is widely used as a feature tree in public parks and gardens in warmer climates such as California, Portugal, Italy, Spain, Malta, northern New Zealand (Auckland), and Australia. Old specimens can reach tremendous size.

The New Zealand rock wren is now restricted to the South Island and is declining in numbers. The range of the rifleman initially contracted with the felling of forests for agriculture, but it has also expanded its range of habitats by moving into plantations of introduced exotic pines, principally the Monterey pine. It also enters other human-modified habitat when it adjoins native forest. Like all New Zealand passerines, the New Zealand wrens are sedentary and are not thought to undertake any migrations.

The finches are primarily granivorous, but euphoniines include considerable amounts of arthropods and berries in their diet, and Hawaiian honeycreepers evolved to utilize a wide range of food sources, including nectar. The diet of Fringillidae nestlings includes a varying amount of small arthropods. True finches have a bouncing flight like most small passerines, alternating bouts of flapping with gliding on closed wings. Most sing well and several are commonly seen cagebirds; foremost among these is the domesticated canary (Serinus canaria domestica).

Owing to its tropical oceanic island location, the Rarotonga monarch is exceptionally long-lived for a bird with a mass of only , having an adult survival of between 85 and 89 percent, a life expectancy of seven to nine years, and a maximum lifespan of around 24 years. These figures are comparable to large Australian passerines like the superb lyrebird or satin bowerbirdSee Australian Bird and Bat Banding Scheme and more than ten times the life expectancies of similar sized Holarctic songbirds.

Some species join mixed feeding flocks now and then; others defend the blooming and fruiting trees and bushes where they forage. Unlike most tropical Asian passerines, the nests of leafbirds are not located low down in the forest, but are instead found on the ends of branches near the tree crown. As such the nests of many species have rarely, if ever, been seen. The nests are open cups; of the few known, they are built of fine stems, leaf parts and rootlets.

In some areas, snowy owls can breed where lemmings are uncommon to essentially absent. Even in Barrow, where the diet is quite homogenously based in lemmings, the hatching of passerines, shorebirds and waterfowl can provide a key resource when lemmings are not found regularly and may be the only means by which the young can survive at such lean times. In the Nome, Alaska area, the locally nesting snowy owls reportedly switched from lemmings to ptarmigans when the latter's chicks hatched.Dufresne, F. (1922).
|
|
Like all passerines, the chicks are altricial; they are born blind and naked, and start to develop down on their heads on day two. Their eyes open around day six, and they begin developing their primary flight feathers around day nine or ten. For the first three days after hatching, the mother feeds the nestlings alone, with food brought to her by the father. The father feeds them directly from the fourth day onwards, with the mother brooding them afterwards until day seven.

Biologist, Doug Robinson, has proposed that scarcity of flying insects in winter is a reason why the flame robin migrates. They have been seen in mixed-species flocks with other small insectivorous passerines, such as scarlet robins, hooded robins (Melanodryas cucullata), white-fronted chats (Epthianura albifrons), and Australasian pipits (Anthus novaeseelandiae). Among the types of insects consumed are many families of beetles, wasps, and ants, flies (families Tabanidae and Asilidae), bugs, and caterpillars. Other invertebrates eaten include spiders, millipedes and earthworms.

Like its relatives, the masked shrike hunts from a perch, typically high, although usually in less exposed locations than those favoured by most other shrikes. Prey is usually taken from the ground, but occasionally picked off foliage or caught in the air with an agile flycatcher-like flight. The kill may be impaled on thorns or barbed wire as a "larder" for immediate or later consumption. Because passerines have relatively weak legs, impalement holds the corpse while it is dismembered.
|
|
Some people who feed and watch birds for entertainment also intentionally feed seeds and nuts to the squirrels for the same reason. However, in the UK eastern gray squirrels can take a significant proportion of supplementary food from feeders, preventing access and reducing use by wild birds. Attraction to supplementary feeders can increase local bird nest predation, as eastern gray squirrels are more likely to forage near feeders, resulting in increased likelihood of finding nests, eggs and nestlings of small passerines.

The lakes are also home to important fish and invertebrates. In the site have been recorded several IUCN Red-Listed species of animals – 5 invertebrates, 4 fish, 4 amphibians, 3 reptiles, 5 birds and 3 mammals. Situated along the second largest migration path of birds in Europe, the Via Pontica, the site is an important stopover and staging site for a large number of water-birds, raptors and passerines. Yearly during migration and wintering more than 20,000 (up to 100,000) waterbirds congregate there.

A feeding trace of Brueelia lice on the tail feather of Barn swallow. Feather holes often characteristically occur on wing and tail feathers of some small- bodied species of passerines. In the case of barn swallows, it was suggested that the holes were feeding traces of avian lice, either Machaerilaemus malleus and/or Myrsidea rustica (both Phthiraptera: Amblycera). Hole counts were shown to be highly repeatable, and thus counts appeared to be useful measures to quantify the intensity of infestation.

More information is needed about their breeding habits in coastal regions as these forests are likely to represent different conditions from their inland counterparts. Fat deposits play a key role in allowing for long distance migration in most passerines. Stopover habitat, or areas that allow birds to replenish their fat stores, are also critical. In winter, these birds migrate to southern Mexico, the Greater Antilles, and Central America particularly along the Caribbean Slope where they occupy both scrub and moist forests.
|
|
At a smaller scale additional partitioning occurs. The golden white-eye shows differences in the preferred microhabitat for obtaining insects, for example, feeding in dead leaves and branches, whereas the bridled white-eye prefers gleaning insects on live leaves. It is the most generalised of all the extant forest passerines on Saipan. It has been suggested that the versatility in diet and foraging technique is an adaptation to the challenges presented by typhoons, which can dramatically alter the structure of the forest.

The males captured in February and March had enlarged testes, typical of breeding birds. The fledgling and an adult with old brood patches were observed in June. These data and song activity from February to April (a dry season) suggest that the breeding season begins early in the year, possibly as early as January, and extends for several months. As in other Grallaria species, the fledgling was less developed than those of most passerines, and both parents fed it earthworms.

The red-vented bulbul (Pycnonotus cafer) is a member of the bulbul family of passerines. It is a resident breeder across the Indian subcontinent, including Sri Lanka extending east to Burma and parts of Tibet. It has been introduced in many other parts of the world and has established itself in the wild on several Pacific islands including Fiji, Samoa, Tonga and Hawaii. It has also established itself in parts of the United Arab Emirates, Bahrain, the United States and Argentina.
|
|
The general pattern seen in passerines is that the primaries are replaced outward, secondaries inward, and the tail from centre outward. Before nesting, the females of most bird species gain a bare brood patch by losing feathers close to the belly. The skin there is well supplied with blood vessels and helps the bird in incubation. Red lory preening Feathers require maintenance and birds preen or groom them daily, spending an average of around 9% of their daily time on this.

Like all figs, the fruit is in the form of a syconium, an inverted inflorescence with the flowers lining an internal cavity. F. rubiginosa is exclusively pollinated by the fig wasp species Pleistodontes imperialis, which may comprise four cryptospecies. The syconia are also home to another fourteen species of wasp, some of which induce galls while others parasitise the pollinator wasps, and at least two species of nematode. Many species of bird, including pigeons, parrots and various passerines, eat the fruit.

They are found alone or in pairs. Fan-tailed warblers are known to engage in commensal feeding, wherein prey that has been roused or disturbed by the foraging or hunting of another animal is opportunistically captured. They have been observed following and foraging for prey near army ants, other passerines, and nine-banded armadillos. The fan-tailed warbler is sometimes placed in the monotypic genus Euthlypis due to its unique morphology, but its nest, eggs, voice, and juvenile plumage are consistent with Basileuterus.
|

Caterpillars are the staple food for nestlings, with some – e.g. those of geometer moths (Geometridae) – preferred over others.Bachynski & Kadlec (2003), Foster (2007) The predators of yellow and mangrove warblers are those - snakes, foxes, birds of prey, and many others - typical of such smallish tree-nesting passerines. The odds of an adult American yellow warbler to survive from one year to the next are on average 50%; in the southern populations, by contrast, about two-thirds of the adults survive each year.

Among bird species preyed upon by the beech marten, sparrow-like birds predominate, though snowcocks and partridges may also be taken. The marten likes to plunder nests of birds including passerines, galliformes and owls, preferring to kill the parents in addition to the fledglings. Although it rarely attacks poultry, some specimens may become specialized poultry raiders, even when wild prey is abundant. Males tend to target large, live prey more than females, who feed on small prey and carrion with greater frequency.

The length of the hindclaw varies with the habits of the species, more arboreal species have shorter, more curved hindclaws than the more terrestrial species. The bills are generally long, slender and pointed. In both size and plumage there is little differences between the sexes. One unusual feature of the pipits, which they share in common with the rest of their family but not the rest of the passerines, is that the tertials on the wing entirely cover the primary flight feathers.
|
|
Golden eagles, being habitual scavengers at carrion, come into conflict with scavenging birds as well. They may encounter corvids at carrion sites and the large passerines are often highly cautious, either feeding some distance from the eagle or waiting until the eagle is done eating, lest they be predaceously grabbed. Occasionally, however, corvids may behave more boldly around golden eagles. In one case, a group of three black- billed magpies were observed to rob a golden eagle of its prey.
|
|
They are partially migratory, and usually breed only in the southern portion of their range, moving north for the dry season in southern Africa. It lays four eggs in a burrow nest at the beginning of the southern African wet season, and the chicks usually hatch at the beginning of December. Unlike most bee-eaters, the species does not practice cooperative breeding and post-fledging dependence is only around 19 days, which is typical of temperate zone passerines and about half that of most Meropidae species.

Bird Island Nature Reserve in Lambert's Bay, Western Cape, South Africa. A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows.

The orioles and figbirds are medium-sized passerines, around 20–30 cm in length, with the females only slightly smaller than the males. The beak is slightly curved and hooked, and, except in the figbirds, as long again as the head. The plumage of most species is bright and showy, although the females often have duller plumage than the males do. The plumage of many Australasian orioles mimics that of friarbirds (a genus of large honeyeaters), probably to reduce aggression against the smaller orioles.

The longevity of a mistletoebird has been recorded in southern Queensland, where a banded adult male was recaptured near the banding site after 9 years. Mistletoebirds vocally mimic other birds. Heard in all seasons and given by both sexes, they have been recorded mimicking the mulga parrot ( Psephotus varius), as well as more than 25 different species of passerines. Predators known to have taken mistletoebird nestlings are the grey shrike-thrush (Colluricincla harmonica), pied butcherbird (Cracticus nigrogularis), pied currawong (Strepera graculina), and the Australian raven (Corvus coronoides).

Robert Sterling Ridgely (b. 14. January 1946) is an American ornithologist, specializing in the neotropics. He is the co-author of three books on neotropical ornithology: the field guide The Birds of Panama (with John Gwynne), The Birds of Ecuador (with Paul Greenfield), and The Birds of South America (with Guy Tudor), of which two monumental volumes (out of four), covering the passerines, have appeared. He was long affiliated with the Academy of Natural Sciences in Philadelphia, then Vice-President at the American Bird Conservancy until 2006.

These birds are birds with relatively slender bodies, long tails and strong legs. The black-bellied cuckoo is essentially restricted to rainforest, but the more widespread squirrel cuckoo also occurs in other forest types, woodlands or mangroves. Piaya cuckoos, unlike many Old World species, are not brood parasites; they build their own nests in trees and lay two eggs. Parasitic cuckoos lay coloured eggs to match those of their passerine hosts, but the non-parasitic Piaya species, like most other non-passerines, lay white eggs.

Calls with the "spark" sounds at end The non-migratory genus Prinia shows biannual moult, which is rare among passerines. A moult occurs in spring (April to May) and another moult occurs in autumn (October to November). Biannual moult is theorized to be favoured when ectoparasite loads are very high, however no investigations have been made. Prinia socialis moults some remiges twice a year and is termed to have a partially biannual moult, however some authors describe P. socialis socialis as having two complete moults.

Cornus sanguinea berries The leaves provide food for some animals, including Lepidoptera such as the case- bearer moth Coleophora anatipennella. Dogberries are eaten by some mammals and many birds. Many frugivorous passerines find them irresistible, and prefer them over fruits grown by humans. The plant is thus often grown in organic gardening and permaculture to prevent harm to orchard crops, while benefitting from the fact that even frugivorous birds will hunt pest insects during the breeding season, as their young require much protein to grow.

Recent studies suggest that New Zealand wrens are Gondwanan descendants. DNA studies seem to indicate that the wrens are the most ancient of all passerines, splitting from the ancestral passerine stock at the time New Zealand become an isolated land mass. In the absence of mammals, birds diversified into the niches usually filled by mammals in other ecosystems. The moas, of which there were eleven species, were large browsers, and were in turn the prey species of the giant Haast's eagle or Harpagornis eagle.

Ridgely, Robert S. and Tudor, Guy; The Birds of South America: Vol. II, The Suboscine Passerines, pp. 27–28 Its natural habitat is entirely within the Patagonian steppe, and it breeds only in areas rain shadowed by the icy Andes in Santa Cruz Province and Tierra del Fuego. Geositta antarctica migrates as far north as Mendoza during the autumn and winter seasons, but keeps to arid areas, and it is most numerous on heavily grazed grassland on the leeward side of Tierra del Fuego.

Its contact call is a thin, high-pitched piping, often repeated, and variously transcribed as siii siii or tsee tsee. The song is more complex, consisting of 4–6 high-pitched notes, the last of which is longer, lower and more burry. Described as "rhythmic but lazy", it has been transcribed as wit-sit-diddley-diddley-ee-ee. Unlike many other passerines, but like all cordon-bleu species, female red-cheeked cordon-bleus sing; they also help to defend a small area around their nest site.

The diet is to some extent opportunistic, but a majority breed and hunt coinciding with ptarmigan and seabird colonies. Avian prey can range in size from redpolls to geese and can include gulls, corvids, smaller passerines, waders, and other raptors (up to the size of Buteos). Mammalian prey can range in size from shrews to marmots (sometimes thrice the weight of the assaulting falcon), and often includes lemmings, voles, ground squirrels, hares and rarely also bats.Mikula, P., Morelli, F., Lučan, R.K., Jones, D.N., & Tryjanowski, P. (2016).

While usually the smallest avian prey selected by Cooper's hawks are various warblers (presumably taken mainly by male hawks), down to the size of the Wilson's warbler (Cardellina pusilla), even smaller passerines are known to be hunted. The smallest known avian prey species have included the verdin (Auriparus flaviceps), the ruby-crowned kinglet (Regulus calendula) and the bushtit (Psaltriparus minimus).Boal, C. W., & Mannan, R. W.

Sjöstedt's barred owlet is a nocturnal species, hunting during the night in the forest understorey. Its diet consists of insects such as grasshoppers, but also spiders, crabs, mice, small snakes and nestling birds. When an owlet is disturbed from its daytime roost, it often results in mobbing behaviour by small birds, e.g. passerines. The breeding season of Sjöstedt's barred owlet is little known, although it lays in July in Gabon and young have been found in nests throughout much of the year in Cameroon.

The Horsfield's bush lark is one of 90 species of larks of the rather large and fairly diverse family, Alaudidae. They are small to medium-small passerines, usually with rather drab, brownish plumage. Predominantly an Old World family, the species are distributed widely across Europe, Africa, Asia and the Indian subcontinent but Horsfield's bush lark is the only species occurring naturally in Wallacea, New Guinea and Australia. The alternate shortened name "bush-lark" can also refer to many of the other species in the genus Mirafra.

True palm trees at Tresco Abbey Gardens in the Isles of Scilly Because of the Gulf Stream, the climate of Scilly is particularly mild so sub-tropical plants can grow there, including true palm trees. Scilly is the first landing for many migrant birds, including extreme rarities from North America and Siberia. Scilly is situated far into the Atlantic Ocean, so many North American vagrant birds will make first European landfall in the archipelago. Scilly is responsible for many firsts for Britain, and is particularly good at producing vagrant American passerines.

Many rare species of bird have been found on the island, with at least 27 species found on the island that were the first British records, and is probably the best place in western Europe to see skulking Siberian passerines such as Pechora pipit, lanceolated warbler and Pallas's grasshopper warbler. For example, in 2015, rare birds discovered on the island included pallid harrier, arctic warbler, Moltoni's warbler, booted warbler, paddyfield warbler, siberian thrush and thrush nightingale. The island is also home to an endemic subspecies of Eurasian wren, the Fair Isle wren Troglodytes troglodytes fridariensis.

Sibley and Ahlquist's DNA-DNA hybridisation studies placed this group in a Corvida parvorder comprising many tropical and Australian passerines, including pardalotes, fairy-wrens, honeyeaters, and crows. However, subsequent molecular research (and current consensus) places the robins as a very early offshoot of the Passerida (or "advanced" songbirds) within the songbird lineage. Measuring 14 to 15 cm (5.5–6 in), the black-chinned robin has a dark brown to black head and upperparts, with a prominent white stripe or "eyebrow" above the eye. The chin is black immediately under the bill.

Among passerines, the most frequently taken are likely to be corvids, which are often favored by Bubo owls from around the world due to their large size, relatively open nests and frequently easy-to-find, communal nocturnal roosts. To date the cape crow (Corvus capensis) and pied crow (Corvus albus) are the corvids reported in dietary studies but in Ethiopia thick-billed ravens (Corvus crassirostris), which at are possible the heaviest corvid species in the world, mobbed them vigorously and seemed to consider them a primary threat.de Castro, J. J., & de Castro, M. (2014).

The smallest family members are the closely related short-tailed pygmy tyrant and black-capped pygmy tyrant from the genus Myiornis (the first species usually being considered marginally smaller on average). These species reach a total length of and a weight of 4–5 grams. By length, they are the smallest passerines on earth, although some species of Old World warblers apparently rival them in their minuscule mean body masses if not in total length.CRC Handbook of Avian Body Masses, 2nd Edition by John B. Dunning Jr. (Editor).

A huge diversity of birds may be taken by tawny owls, although most are not numerically significant. Slightly over half of the avian prey spectrum for tawny owls are various passerines down to the size of Europe's smallest bird, the goldcrest (Regulus regulus). At the other end of the size scale for passerine prey are corvids, including jays, magpies and assorted crows. In some cases, tawny owls have apparently preyed on adult crows of around their own size or slightly larger, such as an estimated carrion crow (Corvus corone).

Eastern phoebe nest with one brown-headed cowbird egg Juvenile in California The brown-headed cowbird is an obligate brood parasite: it lays its eggs in the nests of other small passerines (perching birds), particularly those that build cup-like nests. The brown-headed cowbird eggs have been documented in nests of at least 220 host species, including hummingbirds and raptors. The young cowbird is fed by the host parents at the expense of their own young. Brown-headed cowbird females can lay 36 eggs in a season.

Their eyes have well-developed focus muscles that can change the curvature of the lens to enhance underwater vision. They have nasal flaps to prevent water entering their nostrils. The text is identical to Volume 10 of the print edition published in 2005. The high haemoglobin concentration in their blood gives them a capacity to store oxygen greater than that of other birds, allowing them to remain underwater for thirty seconds or more, whilst their basal metabolic rate is approximately one-third slower than typical terrestrial passerines of similar mass.

In-flight mortality: poor weather conditions can significantly decrease bird populations, especially during migration. Most of weather- related in-flight mortalities are due to heavy storms, mist or rain. Passerines and other small sized birds are particularly affected by adverse in-flight weather conditions, but larger birds such as eagles and swans could also be killed. Mortality on breeding grounds: small, insect eating birds contribute to the majority of post-arrival deaths, but many other birds including waders and waterfowls are also distressed by weather changes on breeding grounds.

The Caribbean martin nests in cavities in banks and buildings, or old woodpecker holes. 3-6 eggs are laid in the lined nest, and incubated for 15 days, with another 26-27 to fledging. Just as the purple martin, this species may compete with other passerines for nesting cavities. In particular, the main foe is the house sparrow in urban areas, where they mostly use man-made structures, whereas in more rural locations Picidae holes in coconut trees are favored, and there is less competition with the sparrows.

The Chilean hawk hunts forest passerines quite indiscriminately of species, habitat or habits provided they have the right size, though it has a preference for species that live closer to the forest floor. Depending on availability, favorite prey species include thorn-tailed rayadito (Aphrastura spinicauda) black-chinned siskin (Carduelis barbata), white-crested elaenia (Elaenia albiceps), Austral thrush (Turdus falcklandii) and fire-eyed diucon (Xolmis pyrope). It has been claimed that the Chilean pigeon (Columba araucana) constitutes important prey, but this seems only to be correct at certain times or places, if at all.

Arctic habitats provide an exceptional area in the summer months for migrating birds looking to breed. In many areas there is an abundance of seasonal arthropods, an extended duration of a 24-hour photoperiod, and a general scarcity of predators (Schekkerman et al. 2003). Shorebirds and Passerines are two of the most speciose groups of birds that rely heavily on the presence of surface swarming Arthropods. The shorebirds are a very precocial group of animals that can all move around and feed for themselves on the day they hatch (Tulp & Schekkerman 2008).

Eulo in southwestern Queensland The red-capped robin is generally encountered alone or in pairs, although groups of up to eight birds—a mated pair and their young—may be seen in autumn and winter.Higgins et al. p. 655. The species may join mixed-species flocks with other small insectivorous passerines; species recorded include the willie wagtail (Rhipidura leucophrys), southern whiteface (Aphelocephala leucopsis), rufous whistler (Pachycephala rufiventris) and black-faced woodswallow (Artamus cinereus) in Queensland, and the chestnut-rumped thornbill (Acanthiza uropygialis), buff-rumped thornbill (A. reguloides) or inland thornbill (A.

In more enclosed wooded areas, radio-tagging and video-monitoring of various passerines nests as well as examinations of owl pellets has shed light on the relationship of barred owls with these potential prey resources. Not only was the barred owl found to be a surprisingly routine predator at woodland passerine nests, but that an unexpected bulk of the acts of predation in studies from Missouri and Illinois were carried out during the daytime. Many different forest bird species (most frequently acadian flycatchers and indigo buntings in Missouri and Illinois) were hunted.

In the North-West of Russia, rough-legged buzzards could feed on small rodents, in the years when rodent density is high, and shift for alternative prey (ptarmigans and hares) in the years when small rodents are scarce. The rough-legged hawk will also supplement its diet with mice, rats, gerbils, pikas and insects. Besides mammals, birds are the second most favored type of prey for rough-legs. Most avian prey species are small passerines such as snow buntings (Plectrophenax nivalis), Lapland longspur (Calcarius lapponicus) and American tree sparrow (Spizelloides arborea).

The order Falconiformes is represented by the extant family Falconidae (falcons and caracaras) and a handful of enigmatic Paleogene species. Traditionally, the other bird of prey families Cathartidae (New World vultures and condors), Sagittariidae (secretarybird) Pandionidae (ospreys), Accipitridae (hawks) were classified in Falconiformes. A variety of comparative genome analysis published since 2008, however, found that falcons are part of a clade of birds called Australaves, which also includes seriemas, parrots and passerines. Within Australaves falcons are more closely to the parrot-passerine clade (Psittacopasserae), which together they form the clade Eufalconimorphae.

Skeleton of American crow (Corvus brachyrhynchos) on display at the Museum of Osteology Corvids are large to very large passerines with a robust build, strong legs and all species except the pinyon jay have nostrils covered by bristle-like feathers. Many corvids of temperate zones have mainly black or blue coloured plumage; however, some are pied black and white, some have a blue-purple iridescence and many tropical species are brightly coloured. The sexes are very similar in color and size. Corvids have strong, stout bills and large wingspans.

T.Moritz and K. E. Linsenmair, West African fish diversity – distribution patterns and possible conclusions for conservation strategies (in African Biodiversity: Molecules, Organisms, Ecosystems, Springer, 2001) The Afrotropic has various endemic bird families, including ostriches (Struthionidae), sunbirds, the secretary bird (Sagittariidae), guineafowl (Numididae), and mousebirds (Coliidae). Also, several families of passerines are limited to the Afrotropics; These include rock-jumpers (Chaetopidae) and rockfowl (Picathartidae). Africa has three endemic orders of mammals, the Tubulidentata (aardvarks), Afrosoricida (tenrecs and golden moles), and Macroscelidea (elephant shrews). The East-African plains are well known for their diversity of large mammals.

Most prey is taken on the ground. Mountain hawk-eagles have also been observed catching passerines on the wing by giving chase from an ambush or when the prey is flushed by flying low at the canopy level. They will also readily take arboreal mammals and birds from a perch or roost if they're able to fly upon them in an ambush. While most of their prey are relatively small, well within typical prey size range for most raptorial birds, mountain hawk- eagles can take remarkably large prey.

In some cases, hungry immature red- tails have been recorded making attempts at hunting prey beyond their capacities, expending valuable energy, such as healthy adults of larger carnivorans such as coyotes (Canis latrans), foxes and badgers and healthy flying passerines. There are some cases of red-tailed hawks, presumably younger than two years of age, attempting to breed, often with an adult bird of the opposite sex. Such cases have been recorded in Alberta, Arizona and Wisconsin, with about half of these attempts being successful at producing young.Millsap, B. A. (1981).

A pish is an imitated bird call (usually a scold or alarm call) used by birders and ornithologists to attract birds (generally passerines). The action of making the sound is known as pishing or spishing. This technique is used by scientists to increase the effectiveness of bird diversity surveys, and by birders to attract species that they might not otherwise see. Pishing is used most effectively in the Holarctic, where it is thought to work due to its similarity to the scold calls of tits and chickadees (birds in the family Paridae).

The more numerous native passerines, such as northern cardinals (Cardinalis cardinalis) and northern mockingbirds (Mimus polyglottos), have good reason to fear these hawks as they are widely and regularly taken as are even common birds of less than half their size (around ), such as song sparrows (Melospiza melodia), dark-eyed juncos (Junco hiemalis) and house finches (Haemorhous mexicanus).Zanette, L., Smith, J. N., Oort, H. V., & Clinchy, M. (2003). Synergistic effects of food and predators on annual reproductive success in song sparrows. Proceedings of the Royal Society of London.

Wrens are medium-small to very small birds. The Eurasian wren is among the smallest birds in its range, while the smaller species from the Americas are among the smallest passerines in that part of the world. They range in size from the white-bellied wren, which averages under and , to the giant wren, which averages about and weighs almost . The dominating colors of their plumage are generally drab, composed of gray, brown, black, and white, and most species show some barring, especially on the tail or wings.

Little is known about the reproductive success and breeding of Psophodes, which is unfortunately the same for the rest of the family Cinclosomatidae. It is known, however, that in the eastern whipbird, the female would produce clutches of two or occasionally three eggs. A feature that can be seen in other Psophodes; it is an evolutionary characteristic of endemic Australian Passerines. The reason for the low number of clutches is not well known, however, it has been put down to limited food availability, predation risk, and seasonal fluctuations in resources.

Characteristics of the appearance of the pallid cuckoo include: a dark bill, a dark eye with a gold eye-ring, a shadowy dark mark from the eye down the neck, a white (or buff) mark on the nape, olive grey feet and prominent white (or buff) toothing along the tail. In flight, there are conspicuous white and dark bars across the long tail. Its silhouette resembles a falcon and often triggers alarm calls from passerines. The pallid cuckoo can have various morphs including light rufous morph or dark rufous morph.

Hundreds of species of birds are also endemic to the region, with gulls and passerines being the most common types sighted around the Eramorsa-Speed River confluence. Multiple species of duck also call the river home, including ring-necked ducks and mallards; as do Canadian geese. Fishes living in the river include the largemouth bass, smallmouth bass, northern pike, rainbow trout, brook trout, brown trout, brown bullhead, and pumpkinseed. The largely-undeveloped upriver sections of the Eramosa River serve as a natural refuge for a number of at- risk and endangered species.

When the mimic becomes more common than the model, it switches and is preyed upon much more often. Therefore, the dishonest signals in prey can be selected for or against depending on predation pressure. An example in birds is observed within ground dwelling passerines, in which the wild birds were kept in their natural habitat but were presented with dimorphic prey (artificial). The two colors of prey were present in 9:1 ratios, and then the prey were switched so both colors were in the higher and lower ratio.

In the afternoon, most pairs engage in social activities, which often take place at "social trees". The zebra finch frequently does not breed where it was born; of the ringed birds that bred in the Danaher breeding colony () from 1985 to 1989, 24% of them were hatched from the colony or in the immediate vicinity. This natal dispersal is not sex-biased, unlike in most passerines. However, males between 36 and 50 days of age are more likely to disperse than females, although after this age, more females disperse than males.

Its food consists mainly of rodents, especially voles, but it will eat other small mammals such as mice, ground squirrels, shrews, rats, bats, muskrats and moles. It will also occasionally predate smaller birds, especially when near sea-coasts and adjacent wetlands at which time they attack shorebirds, terns and small gulls and seabirds with semi-regularity. Avian prey is more infrequently preyed on inland and centers on passerines such as larks, icterids, starlings, tyrant flycatchers and pipits. Insects supplement the diet and short-eared owls may prey on roaches, grasshoppers, beetles, katydids and caterpillars.

These were the crested bunting (Melophus lathami), the slaty bunting (Latouchiornis siemsseni), and the corn bunting (Miliaria calandra). All three species are now included in the genus Emberiza. A large DNA-based study of the passerines published in 2019 found that the buntings are most closely related to the longspurs and snow buntings in the family Calcariidae. Ornithologists Edward Dickinson and Leslie Christidis in the fourth edition of the Howard and Moore Complete Checklist of the Birds of the World chose to split up Emberiza and recognise the genera Fringillaria, Melophus, Granativora, Emberiza, and Schoeniclus.

Finally, the western subspecies lays eggs averaging in size which are pale shades of red- brown or wine-colour, with darker red-brown markings. In all subspecies, the markings can coalesce over the larger end of the egg to form a darker 'cap'. The incubation period is poorly known because of the difficulty of observing nests, but one observation suggested around 23 days from laying to hatching. Like all passerines, the chicks are born naked, and blind (altricial), and remain in the nest for an extended period (nidicolous).

Nesting mossy-nest swiftlets The nest of many species is glued to a vertical surface with saliva, and the genus Aerodramus use only that substance, which is the basis for bird's nest soup. The eggs hatch after 19 to 23 days, and the young leave the nest after a further six to eight weeks. Both parents assist in raising the young. Swifts as a family have smaller egg clutches and much longer and more variable incubation and fledging times than passerines with similarly sized eggs, resembling tubenoses in these developmental factors.

However, there are records, particularly during migration periods, of chimney swifts feeding well after dark over brightly lit buildings. The species shows two-weight peaks each year: one at the start of the breeding season, and a higher one shortly before it begins its migration south in the autumn. Its lowest weights are typically recorded during the breeding season, when it also begins a complete molt of its plumage. The chimney swift's weight gain before migration is smaller than that of some passerines, suggesting that it must refuel en route at various stopover points.

They have long, strong legs (for passerines) with which many species hop through undergrowth searching for arthropods and fruits to eat. Their habitat varies from forest undergrowth to scrub, high-altitude grasslands, and deserts. The two tremblers live in the atypical habitat of rain forests in the Lesser Antilles, and the brown trembler has the particularly atypical behavior of foraging while clinging to tree trunks. All known species build somewhat messy, bulky twig nests in dense growth, in most species on the ground or no more than 2 meters up.
|
|
They have a single fossa at the head of the humerus, rather than the double fossae of other passeroid songbirds, but typical of corvoid songbirds. Linear classifications have generally placed them at the beginning of the oscine passerines whereas, based on DNA–DNA hybridization they were placed in the super-family, Passeroidea. However, recent studies based on sequence data, have unanimously shown them to be part of the super-family Sylvioidea. Together with the morphologically and ecologically radically different monotypic genus, Panurus (Panuridae), they form a sister clade to the rest of the Sylvioidea.

Flyways may not be the shortest route available but may have curves or doglegs. Birds of different species may follow similar routes, and populations from one area may merge with other groups and diverge to reach different destinations. Flyways tend to avoid obstacles such as mountain ranges and oceans, running parallel to the barriers and following routes along the coast or along major river valleys. Passerines often fly on a broader front across the terrain, either flying over or circumventing obstacles on the route, according to their evolutionary adaptations.

It is readily distinguished from other mid-sized passerines, such as thrushes, icterids or small corvids, by its relatively short tail, sharp, blade-like bill, round-bellied shape and strong, sizeable (and rufous-coloured) legs. In flight, its strongly pointed wings and dark colouration are distinctive, while on the ground its strange, somewhat waddling gait is also characteristic. The colouring and build usually distinguish this bird from other starlings, although the closely related spotless starling may be physically distinguished by the lack of iridescent spots in adult breeding plumage.Cabe, Paul R. 1993.

Like all passerines, the chicks are altricial; they are hatched naked, with reddish bodies, pale grey down, and closed eyes. The mother bird feeds her young regurgitated seeds and insects as they grow. The hatchlings develop quickly, opening their eyes after three days, and completing the growth of olive-brown juvenile plumage after 11–15 days, at which time they begin to practice short flights close to the nest. For up to three weeks after fledging, they are still fed by the male, who locates them by listening for their fledging call.

Originally, the land had belonged to the Govan family since the late 1800s. The tract only consists of half an acre, but within the tract, the mass availability of lives oaks, hackberries, dewberry, and poison oak attracts birds such as painted buntings, red-winged blackbirds, warblers, and other passerines that can be seen during the migratory season. In addition to the Grand Isle Birding Trail, bird watchers can also see marine birds such as gulls, terns, pelicans, and other shorebirds from the Grand Isle State Park located at the northeast end of the island.

They form monogamous pair bonds to raise their young, laying their eggs in small nests in trees or amongst rocks. They are diurnal and like all New Zealand passerines, for the most part, are sedentary. New Zealand wrens, like many New Zealand birds, suffered several extinctions after the arrival of humans in New Zealand. Two species became extinct after the arrival of the Māori and the Polynesian rat and are known today only from fossil remains; a third, Lyall's wren, became extinct on the main islands, surviving only as a relict population on Stephens Island in the Cook Strait.

In Coen, an old babbler nest in a paperbark (Melaleuca), which had been lined with messmate bark, had been occupied by blue-faced honeyeaters and re-lined with strips of paperbark. Two or, rarely, three eggs are laid, 22 × 32 mm (1 × 1⅓ in) and buff-pink splotched with red-brown or purplish colours. The female alone incubates the eggs over a period of 16 or 17 days. Like those of all passerines, the chicks are altricial; they are born blind and covered only by sparse tufts of brown down on their backs, shoulders and parts of the wings.

Like all Australian robins, it is not closely related to either the European robin or the American robin, but belongs rather to the Corvida parvorder comprising many tropical and Australian passerines, including pardalotes, fairy-wrens, and honeyeaters, as well as crows. Initially thought to be related to Old World flycatchers, it was described as Muscicapa cucullata by the English ornithologist John Latham in 1801. Later described as Grallina bicolor by Nicholas Aylward Vigors and Thomas Horsfield, The title page of the issue has the year 1826. it was later placed in the genus Petroica for many years before being transferred to Melanodryas.

A 2009 study of the DNA of the families Timaliidae and the Old World warblers (Sylviidae) found no support for the placement of the genus in either family, prompting the authors to erect a new monogeneric family, the Pnoepygidae. This genus of diminutive passerines has a mostly montane distribution in South and South East Asia. The scaly-breasted cupwing is found in the mountainous areas of north India eastwards to southern China and northern Vietnam. The Taiwan cupwing is endemic to Taiwan, and similarly the Nepal cupwing has a restricted distribution, mostly occurring in Nepal (and also slightly into India).

Breeding male Brewer's blackbird apparently gaping (see text) in soil Icterids are variable in size, and often display considerable sexual dimorphism, with brighter coloration and greater size in males being typical. While such dimorphism is widely known in passerines, the sexual dimorphism by size is uniquely extreme in icterids. For example, the male great-tailed grackle is 60% heavier than the female. The smallest icterid species is the orchard oriole, in which the female averages 15 cm in length (6 in) and in weight, while the largest is the Amazonian oropendola, the male of which measures and weighs about .

The Coraciiformes are a group of usually colorful birds including the kingfishers, the bee-eaters, the rollers, the motmots, and the todies. They generally have syndactyly, with three forward-pointing toes (and toes 3 & 4 fused at their base), though in many kingfishers one of these is missing. This is largely an Old World order, with the representation in the New World limited to the dozen or so species of todies and motmots, and a mere handful of the more than a hundred species of kingfishers. The name Coraciiformes means "raven-like", which is a misnomer (ravens are passerines).

He succeeded in curbing the migratory instinct in young birds and persuaded the government of France to conduct initial testing, but further experimentation stalled. Subsequent attempts to train homing behaviour into swallows and other passerines had difficulty establishing a statistically significant success rate, although the birds have been known to trap themselves in a cage repeatedly to get to the bait. According to a sailing superstition, swallows are a good omen to those at sea. This probably arose from the fact that swallows are land-based birds, so their appearance informs a sailor that he is close to shore.

The passerines (songbirds), besides being the most diverse order in Brazil, is also the order with most species on Brazilian red list, immediately before the Parrots. The Brazilian Northeast, notably in Atlantic forest and Caatinga, has the most number of endemic and threatened birds, and two of them, the Alagoas curassow and the Spix's macaw, has been considered extinct in the wild. The "Pernambuco Center" of endemism presents many critically endangered species due to the intense destruction of the Atlantic forest. Some species might be extinct in Brazil, like the Glaucous macaw and the Eskimo curlew.

Ornithologist Brian Bell found that prions were confined to cliff faces at Crozier Point in 1962 and noted "any bird landing...[fell] an immediate prey to the feral cats.". Gut content and scat analysis show that cats are feeding on small passerines and seabirds. A cat was seen feeding on a pre-fledging juvenile white-capped mollymawk at South West Cape. Goats were introduced to the Auckland Islands several times in the second half of the nineteenth century, to serve as a source of food for castaway sailors, with at least one liberation in 1865 on the main Auckland Island.

The thick-billed raven (Corvus crassirostris), a corvid from the Horn of Africa, shares with the common raven the distinction of being the largest bird in the corvid family, and indeed the largest of the passerines. The thick- billed raven averages in length, with a range of and weighs approximately in females and in males on average. Its size is about the same as the largest races of common raven (i.e. those from the Himalayas and Greenland/Canadian Northwest Atlantic) but some common raven subspecies are rather smaller and, going on average weights, the thick-billed raven is likely the heaviest extant passerine.

The Cuban martin nests in cavities in banks and buildings, or old woodpecker holes. 3-6 eggs are laid in the lined nest, and incubated for 15 days, with another 26-27 to fledging. Just as the purple martin, this species may compete with other passerines for nesting cavities. In particular, the main foe is the house sparrow Steven Kroenke, House Sparrow Revenge Syndrome , November 11, 1999, The Purple Martin Forum Archives in urban areas, where they mostly use man-made structures, whereas in more rural locations Picidae holes in coconut trees are favored, and there is less competition with the sparrows.

The Passerines, albeit still quite precocial, need a few days of being fed by the parents until they get to the point where they can acquire their own food resources (Tulp & Schekkerman 2008). The insects of this region are also characterized by having a very short period of conspicuous activity. Many of them overwinter as larvae burrowed in the sediment in a state of diapause, waiting for the snow to melt and the ice to free from the ponds (Maclean & Pitelka 1971). Once clear, the animals can continue their development, that can take as long as 7 years (Butler 1982).

The order is divided into three suborders, Tyranni (suboscines), Passeri (oscines), and the basal Acanthisitti. Oscines have the best control of their syrinx muscles among birds, producing a wide range of songs and other vocalizations (though some of them, such as the crows, do not sound musical to human beings); some such as the lyrebird are accomplished imitators. The acanthisittids or New Zealand wrens are tiny birds restricted to New Zealand, at least in modern times; they were long placed in Passeri. Pterylosis or the feather tracts in a typical passerine Most passerines are smaller than typical members of other avian orders.

A tendon in the rear of the leg running from the underside of the toes to the muscle behind the tibiotarsus will automatically be pulled and tighten when the leg bends, causing the foot to curl and become stiff when the bird lands on a branch. This enables passerines to sleep while perching without falling off.Stefoff, Rebecca (2008), The Bird Class, Marshall Cavendish BenchmarkBrooke, Michael and Birkhead, Tim (1991) The Cambridge Encyclopedia of Ornithology, Cambridge University Press . Most passerine birds have 12 tail feathers but the superb lyrebird has 16,Jones, D. (2008) "Flight of fancy".

There are few passerines (perching birds), perhaps because of a lack of nesting opportunities or a dearth of insect food at some times of year. The rivers and lakes are home to Atlantic salmon, brown trout and Arctic char, as well as European eel and three-spined stickleback, and there are rainbow trout which have escaped from fish hatcheries. There are no amphibians or reptiles on Iceland. Around 270 species of marine fish occur in the waters around Iceland, with the most important commercial species being cod, haddock, sea perch, plaice, herring, capelin and blue whiting.

Like other nuthatches they have strongly curved claws that allow them to climb down vertical tree trunks, unlike species such as woodpeckers that only work their way upwards. It moves jerkily up and down or around tree branches and trunks. It is an active feeder on insects and spiders, gleaned on the bark of the trunk and branches, and may be found in mixed feeding flocks with other passerines. The insects they disturb are sometimes taken by the racket-tailed drongo in Sri Lanka. This is a noisy bird, often located by its repeated “sit-sit-sit” call.

They seldom rely on camouflage, instead often flying at the least disturbance and not allowing close approaches, making them potentially difficult to observe. Yet, on the other hand, they can be surprisingly tame and seemingly curious of people in the wild; further they are considered "as mild and engaging" as a predator can be. Barred owls are regularly subject to mobbing by small birds, from several small passerines to corvids and woodpeckers, and mammals when discovered by them during the daytime, and such situations may lead to them being attacked by diurnal birds of prey.Carter, J. D. (1925).

Because of their large eggs, rayadito females (and indeed all other documented furnariids) lay eggs only every other day, akin to other south temperate passerines like the rifleman and thornbills, though their incubation periods are not as long.Ricklefs, R.E.; "Sibling competition, hatching asynchrony, incubation period, and lifespan in altricial birds"; in Power, Dennis M. (editor); Current Ornithology. Vol. 11. Although rayaditos were historically thought to be multi-brooded,Sieving, Kathryn E; Willson, Mary F. and de Santo, Toni L.; "Defining Corridor Functions for Endemic Birds in Fragmented South Temperate Rainforests" in Conservation Biology; Vol. 14, No. 4 (August 2000); pp.

Partial migration can form a large percentage of the migration behaviour of birds in some regions; in Australia, surveys found that 44% of non-passerine birds and 32% of passerines were partially migratory. Altitudinal migration is a form of short-distance migration in which birds spend the breeding season at higher altitudes and move to lower ones during suboptimal conditions. It is most often triggered by temperature changes and usually occurs when the normal territories also become inhospitable due to lack of food. Some species may also be nomadic, holding no fixed territory and moving according to weather and food availability.

It is exceptionally efficient at digesting its food, and disgorges only tiny pellets of fragmented bone, fur and feathers. A 2006 study of inland bodies of water around Canberra where wedge-tailed eagles and white-bellied sea eagles share territories showed little overlap in the range of prey taken. Wedge- tailed eagles took rabbits, various macropods, terrestrial birds such as cockatoos and parrots, and various passerines including magpies and starlings. White-bellied sea eagles caught fish, water-dwelling reptiles such as the eastern long-necked turtle and Australian water dragon, and waterbirds such as ducks, grebes and coots.
|

However, this is dwarfed by the largest avian prey credited to a white-tailed eagle, an adult male great bustard (Otis tarda), which weighed an estimated (which, much like exceptionally large fish taken, must have been consumed in the killing spot or subsequently dismantled as too large to fly with). Among the land birds taken, more than 20 passerines are included in the prey spectrum but most are obviously too small and swift to be anything but incidental prey. The smallest avian prey known for white-tailed eagles was a great tit (Parus major), a species which weighs on average.Müller, H. (2011).

Unlike most North American passerines, which develop their adult plumage in their first year of life, so that the one-year- old and the oldest individual are indistinguishable in the breeding season, the sergeant thrush does not. it acquires until after the breeding season of the year following its birth, when it is between thirteen and fifteen months of age. Young males go through a transition stage in which the wing spots have an orange coloration before acquiring the most intense tone typical of adults. The male measures between 22 and 24 cm in length, while the female, 17 or 18 cm.

Eating a finch in a backyard with feeders Other passerines families (i.e. outside thrushes, corvids and icterids) tend to not be as large-bodied and, although by no means neglected, are seldom equal in overall dietary importance (biomass). About 15 species of tyrant flycatcher, several species each of vireo, swallows, tits, nuthatches, wrens, mimids, about a dozen species of finch, cardinalids and a huge diversity of American sparrows and New World warblers (nearly 30 species each) are known to be taken by Cooper's hawks. A lower diversity are taken of shrikes, larks, penduline tits, aegithalids, treecreepers, dippers, silky- flycatchers and longspurs.

The species has a variety of calls; the two most common being the alarm call, made when possible predators (such as humans or other mammals) enter the colonies, and the advertising call. The advertising call is social in nature, made when returning to the colony and during aggressive encounters between individuals. It is unique to each individual tern and as such it serves a similar role to the bird song of passerines, identifying individuals. Eight other calls have been described, from begging calls made by females during mating to attack calls made while swooping at intruders.

The Collins Bird Guide is a field guide to the birds of the Western Palearctic. Its authors are Lars Svensson, Killian Mullarney, Dan Zetterström and Peter J. Grant, and it is illustrated by Killian Mullarney and Dan Zetterström (with two plates of North American passerines contributed by Larry McQueen). It has been described as "undoubtedly the finest field guide that has ever been produced", and "the last great bird book of the 20th century". It was originally published in Swedish and Danish in 1999, and in English in hardback in the same year, and later in paperback.

Pleasanton, California The American bushtit inhabits mixed open woodlands, often containing oaks and a scrubby chaparral understory; it also inhabits parks and gardens. It is a year-round resident of the western United States and highland parts of Mexico, ranging from Vancouver through the Great Basin and the lowlands and foothills of California to southern Mexico and Guatemala. The American bushtit is one of the smallest passerines in North America, at in length and in weight. It is gray-brown overall, with a large head, a short neck, a long tail, and a short stubby bill.

The International Union for the Conservation of Nature lists the golden-crowned sparrow as a species of least concern. The sparrow's extremely large range and population size lift it well above the thresholds used to designate an imperiled species, and data from Christmas Bird Counts show that its numbers are stable or increasing. Throughout its range, it is protected by the Migratory Bird Treaty Act of 1918, and many of its wintering grounds are in protected areas, including national forests and national wildlife refuges. As with other flock-living passerines, the golden-crowned sparrow is prone to elevated levels of feather mites.

|
The incubation period is not well known, due to the difficulty of observing nests, but observations indicate around 30 days from laying to hatching. Like all passerines, the chicks are born naked, and blind (altricial), and remain in the nest for an extended period (nidicolous) They quickly grow a layer of ashy-grey down. Both parents feed the young, although the male does not begin to feed them directly until a few days after birth. The channel-billed cuckoo (Scythrops novaehollandiae) parasitizes pied currawong nests, laying eggs which are then raised by the unsuspecting foster parents.

The timber used was poles of pine, a reflection on the local availability of the tree at the time it was built. On drier patches plants include the dwarf shrubs heather and cross-leaved heath, in wetter places common cottongrass, hare's-tail cottongrass, bog cranberry, bog-rosemary, bog- myrtle and several species of Sphagnum moss. The invertebrate fauna includes the rare mire pill beetle, and other uncommon species of beetle, the bog rush cricket and the large heath butterfly. Birds that breed here include various heathland passerines as well as the nightingale, nightjars and three species of owl.

Christiaan Both studied density dependent reproduction during his PhD, where he aimed to understand why birds lay smaller clutches when competition increased. This work was both using long-term data from hole-breeding passerines, and also experimental. It showed that great tit clutch size is causally affected by local density, and that the density dependent response could be explained by an optimal response of individuals to the level of competition for food during the nestling phase. From 1998 Christiaan Both, Niels Dingemanse, Piet Drent and Joost Tinbergen have studied great tits' exploration and showed that this variation in personality traits is heritable.

Similarly, in northern Ireland, birds were roughly equal in import to mammals but most were unidentified corvids. In Seversky Donets, Ukraine, birds and mammals both made up 39.3% of the foods of buzzards. Common buzzards may hunt nearly 80 species passerines and nearly all available gamebirds. Like many other largish raptors, gamebirds are attractive to hunt for buzzards due to their ground-dwelling habits. Buzzards were the most frequent predator in a study of juvenile pheasants in England, accounting for 4.3% of 725 deaths (against 3.2% by foxes, 0.7% by owls and 0.5% by other mammals).Parrott, D. (2015).

Evidence from different parts of the range shows females select larger prey than males, with males largely keeping to small to mid-sized passerines while females often prey on larger prey such as currawongs, gamebirds (including megapodes) and even herons. Pigeons and parrots are a popular prey item for grey goshawks. Evidence indicates that this species is less agile in the air and less skilled at twisting pursuits over the ground than co-occurring brown goshawks but, on the other hand, the grey species is more powerful and so select typically larger prey.Olsen, P. D., Debus, S. J. S., Czechura, G. V., & Mooney, N. J. (2016).

The primary foods by genera of timber rattlesnakes were as follows: Peromyscus (33.3%), Microtus (10.9%), Tamias (qv) (10.6%), Sylvilagus (10.4%), Sigmodon (5.3%) and Sciurus (4.2%). Based on examination of the snout-to-vent length, it was found that juvenile timber rattlesnakes differed slightly in dietary preferences from adult rattlesnakes, being more likely to consume smaller prey such as shrews (averaging and unable to attack subadult eastern cottontail rabbits (averaging but Peromyscus was the number one prey item for both young and adult rattlesnakes. Several birds, although always secondary to mammals, are also known to be hunted, mainly ground- dwelling species such as bobwhites, but also a surprising number of passerines.

It is not known if the extinct species migrated, but it is considered highly unlikely, as three of the extinct species were flightless. The situation with the New Zealand rock wren is an ornithological mystery, as they are thought to live above the snow line where obtaining food during the winter would be extremely difficult. Searches have found no evidence that they move altitudinally during the winter, but they are also absent from their normal territories. They may enter a state of torpor (like the hummingbirds of the Americas or a number of Australian passerines) during at least part of the winter, but this has not yet been proved.

Biological Conservation 117 (2004) 529–537 The Afrotropic has various endemic bird families, including ostriches (Struthionidae), mesites, sunbirds, secretary bird (Sagittariidae), guineafowl (Numididae), and mousebirds (Coliidae). Also, several families of passerines are limited to the Afrotropics. These include rock-jumpers (Chaetopidae), bushshrikes (Malaconotidae), wattle-eyes, (Platysteiridae) and rockfowl (Picathartidae). Other common birds include parrots (lovebirds, Poicephalus, Psittacus), various cranes (crowned cranes, blue crane, wattled crane), storks (marabous, Abdim's stork, saddle-billed stork), herons (slaty egret, black heron, goliath heron), shoebill, bustards (kori bustard, Neotis, Eupodotis, Lissotis), sandgrouse (Pterocles), Coraciiformes (bee-eaters, hornbills, Ceratogymna), phasianids (francolins, Congo peafowl, blue quail, harlequin quail, stone partridge, Madagascar partridge).

Feeding trace of Brueelia lice on a tail feather Barn swallows (and other small passerines) often have characteristic feather holes on their wing and tail feathers. These holes were suggested as being caused by avian lice such as Machaerilaemus malleus and Myrsidea rustica, although other studies suggest that they are mainly caused by species of Brueelia. Several other species of lice have been described from barn swallow hosts, including Brueelia domestica and Philopterus microsomaticus. The avian lice prefer to feed on white tail spots, and they are generally found more numerously on short-tailed males, indicating the function of unbroken white tail spots as a measure of quality.

The native fauna is composed of various animal species that inhabit the different existing ecosystems. Among the mammals, the taruca, the deer, the llama, the spectacled bear and the fox stand out in the thickest areas of the puna forests, and rodents such as the vizcacha and the muca in the stony areas. There is also a great diversity of birds: raptors, such as the condor, sparrowhawk and kestrel, and nocturnal, such as the owl; waterfowl, such as the Andean duck, and passerines, such as the house sparrow, goldfinch, and nightingale. It is worth noting the existence of migratory birds, such as the swallows, which nest during the winter in wetlands.

Vegetable matter forms part of the jackal diet, and in India they feed intensively on the fruits of buckthorn, dogbane, Java plum, and the pods of mesquite and the golden rain tree. The jackal scavenges off the kills made by the lion, tiger, leopard, dhole, and gray wolf. In some regions of Bangladesh and India, golden jackals subsist by scavenging on carrion and garbage, and will cache extra food by burying it. The Irish novelist, playwright and poet, Oliver Goldsmith, wrote about the golden jackal: In the Caucasus and Transcaucasia, golden jackals primarily hunt hares and mouse-like rodents, and also pheasants, francolins, ducks, coots, moorhens, and passerines.

In total there are 190 species in 55 genera, roughly half of them native to Australia, many of the remainder occupying New Guinea. With their closest relatives, the Maluridae (Australian fairy-wrens), Pardalotidae (pardalotes), and Acanthizidae (thornbills, Australian warblers, scrubwrens, etc.), they comprise the superfamily Meliphagoidea and originated early in the evolutionary history of the oscine passerine radiation. Although honeyeaters look and behave very much like other nectar-feeding passerines around the world (such as the sunbirds and flowerpeckers), they are unrelated, and the similarities are the consequence of convergent evolution. The extent of the evolutionary partnership between honeyeaters and Australasian flowering plants is unknown, but probably substantial.

Gyrfalcons and Ptarmigan in a Changing World. The Peregrine Fund, Boise, Idaho, USA. The reliance on ptarmigan has caused some conservation trickle-down concern for the owls because ptarmigan are hunted in large numbers, with the hunters of Norway permitted to cull up to 30% of the regional population. In North America, avian prey on the breeding ground regularly varies from small passerines like snow buntings (Plectrophenax nivalis) and Lapland longspurs (Calcarius lapponicus) to large waterfowl like king (Somateria spectabilis) and common eider (Somateria mollissima) and usually the goslings but also occasionally adults of geese such as brants (Branta bernicla), snow geese (Anser caerulescens) and cackling geese (Branta hutchinsii).

In addition the specifics of the morphology of the leg differed, with sittellas having leg muscles more similar to those of the honeyeaters. Their placement was then moved to various families, including the Old World babblers (an infamous wastebasket taxon), the true treecreepers (Certhiidae, which range across the Holarctic and Africa) and the Australian treecreepers (Climacteridae). Their relationship with the Australian radiation of passerines was suggested by S.A. Parker on the basis of egg colour, nest structure and nestling plumage, and their position in this radiation was vindicated by Sibley and Ahlquist's DNA–DNA hybridization studies. These researchers placed the sittellas in a monotypic tribe within the superfamily Corvoidea.

The primary purpose for which the Refuge was created is its "...particular value in carrying out the national migratory bird management program." The Refuge's interspersion of wetland, forested upland and old field habitats is ideally suited for this purpose. The Refuge supports a diverse mix of migratory birds including waterfowl, wading birds, raptors, shorebirds, passerines, as well as resident mammals, reptiles, amphibians, fish and invertebrates. The extensive and regionally significant wetlands occurring on and adjacent to the Oxbow Refuge, including their associated tributary drainages and headwaters, have been listed as a priority for protection under both the North American Waterfowl Management Plan and the Emergency Wetlands Resources Act of 1986.

In 1886, the committee released The Code of Nomenclature and Check-List of North American Birds, both a consistent checklist and a set of rules for the naming of birds to be described in the future. The Code settled the disagreement about capitalization of species names and established today's order of presentation, with waterbirds first and passerines last. Several of the handbook's innovations were adopted by other branches of zoology, and were incorporated into the 1905 version of the International Code of Zoological Nomenclature. The committee's work served to standardize the way that birds are described, identifying them at the subspecies level and using a three-part trinomial name.

Recent studies have illustrated that the white- crowned sparrow, as well as other passerines, have the capability of sleeping most significantly during the migratory season while in flight. However, the sleep patterns in this study were observed during migratory restlessness in captivity and might not be analogous to those of free-flying birds. Free- flying birds might be able to spend some time sleeping while in non-migratory flight as well when in the unobstructed sky as opposed to in controlled captive conditions. To truly determine if birds can sleep in flight, recordings of brain activity must take place during flight instead of after landing.

Their legs and feet are weak and short, and trogons are essentially unable to walk beyond a very occasional shuffle along a branch. They are even incapable of turning around on a branch without using their wings. The ratio of leg muscle to body weight in trogons is only 3 percent, the lowest known ratio of any bird. The arrangement of toes on the feet of trogons is also unique among birds, although essentially resembling the zygodactyl's two forward two backward arrangement of parrots and other near- passerines, the actual toes are arranged with usually inner hallux being the outer hind toe, an arrangement that is referred to as heterodactylous.

The male will keep lookout either on the nest or perched on a nearby branch, rather than brood, while the female is foraging; and both parents will feed young and dart off quickly, if there are predators in the vicinity.Higgins et al. p. 657. Extra-pair mating and fertilisation is fairly common, with 23% of nestlings and 37% of broods having a different father to the one rearing them, and there is some evidence that extra-pair couplings are more likely to produce male birds. Like all passerines, the chicks are altricial; they are born blind and covered only by a thin layer of down.

Roles of prey traits, prey class, environmental variables, and taxonomic specialization. Ecology and evolution, 8(6), 3382-3392. No specific variety of bird is subject to the most frequent predation by barred owls and birds are the most diverse class in these owl’s prey spectrum, with more than 100 species of bird known to be hunted. About 60% of bird species in the prey spectrum and nearly 54% of the frequency (in 7077 prey items) amongst birds known to be hunted are passerines, which are generally small, active and diurnal denizens that predominate among the species composition of the woodlands inhabited by barred owls.

The young fledge at 6 to 8 weeks. However, the young typically accompany and are fed by their parents for several months even into the stage that they can fly well, the total dependence period usually lasting 5 to 9 months before independence, and sometimes into the next breeding season. Although there are practically no predators of this species except, in very rare, anecdotal instances, wedge-tailed eagles (Aquila rapax) and powerful owls have been recorded killing each other in territorial and breeding skirmishes. Also, they are often victim to and occasionally even injured by heavy mobbing by larger passerines such as currawongs, magpies, and crows and ravens.

The golden white-eye is also aggressive towards the smaller bridled white-eye, chasing it away from food and perches and flying through flocks of them in order to disperse them. While it chases other forest passerines, it is less aggressive towards them, and in fact the rufous fantail seeks out the golden white-eye, foraging behind it to snatch insects flushed by the latter species. The golden white-eye is socially dominant over the bridled white-eyes and rufous fantails, but it is subordinate to the Micronesian myzomela and is chased by that species. It is also occasionally chased by the fantails if it approaches their nests too closely.

Nests are dome-shaped with a side entrance and are made from grass, narrow leaves, rootlets, moss, and lichens. They are placed anywhere from eye level to 15 m up in stream bank niches, roadside banks, on tree trunks, on branches or palm fronds, within epiphytes or in clumps of moss. Yellow-throated euphonias were found to lay an average of five eggs at one-day intervals with incubation lasting about 15 days and female brooding of the young through day 6 or 7 after hatching. This clutch size is among the highest reported for neotropical passerines with other species of euphonia typically laying three to four eggs per clutch.

A study of the avian prey of the bat revealed that over fifty species of birds are targeted, in a range of sizes but a preference for those weighing less than 35 grams. Birds that roost in flocks make up a large part of the diet, and a quarter of the species are non-passerines. One nocturnal species of bird is recorded at their middens, the Australian owlet-nightjar Aegotheles cristatus. The examination of the butchered remains of their middens has given support to interpretation of fossil depositions, that have similar assemblages of discarded remains, at the Riversleigh formations where this and other species of Macroderma are exceptionally well represented.

However, if there are a large number of individuals in an area as well as multiple food sources, this species will exhibit very little territoriality. Unlike most passerines, the agonistic call of the black-chinned hummingbird is acoustically complex, with notes ordered in non-random patterns, and are even more complex than their songs. This species also uses diving displays ( dives) for territory defense as well as courtship, producing a variety of tones as air passes through their feathers during the plunge. The female builds a well- camouflaged nest in a protected location in a shrub or tree using plant fibre, spider webs and lichens.

Wintering typical pale-morph hawks in Arkansas were found to perch in open areas near the top of tall, isolated trees, whereas dark morphs more frequently perched in dense groups of trees. For many, and perhaps most, red-tailed hawks being mobbed by various birds is a daily concern and can effectively disrupt many of their daily behaviors. Mostly larger passerines, of multiple families from tyrant flycatchers to icterids, will mob red-tails, despite that other raptors such as Accipiter hawks and falcons are a notably greater danger to them. The most aggressive and dangerous attacker as such is likely to be various crows or other corvids, i.e.

However, such a drastic reduction may be very difficult to implement in many areas, and low to moderate densities of deer or other large mammal hosts may continue to feed sufficient adult ticks to maintain larval densities at high levels. Routine veterinary control of ticks of domestic animals, including livestock, by use of acaricides can contribute to reducing exposure of humans to ticks. In Europe, known reservoirs of Borrelia burgdorferi were 9 small mammals, 7 medium-sized mammals and 16 species of birds (including passerines, sea-birds and pheasants). These animals seem to transmit spirochetes to ticks and thus participate in the natural circulation of B. burgdorferi in Europe.

It will also take prey and some fruit like tamanqueiro (Alchornea glandulosa) or gumbo-limbo (Bursera simaruba): Pascotto (2006), Foster (2007). from vegetation by gleaning and jumping for it or ripping it off in mid-hover, and occasionally dives for fish or tadpoles in shallow water, making it one of the few fishing passerines. Kiskadees like to hunt on their own or in pairs, and though they might be expected to make good use of prey flushed by but too large for the smaller birds of the understory, they do not seem to join mixed-species feeding flocks very often. When they do, they hunt in the familiar manner.

The common feral pigeon was the second most prevalent prey species in Sierra Espuña Regional Park in Spain, making up 18.8% of a sampling of 99 from 5 nests. The species was also prevalent in Slovakia, making up 7.4% of remains at nests there. Non-corvid passerines are usually ignored as prey but large thrushes such as song thrush (Turdus philomelos), mistle thrush (Turdus viscivorus) and common blackbird (Turdus merula), are semi-regularly recorded prey in Europe. This family is most prevalent in Sicily, making up 8.1% of a sampling of 74 from 10 nests there, 7.7% in Central Spain and 7.2% in the French Alps.

As no evidence indicates passerines were flightless when they arrived on New Zealand (that apomorphy is extremely rare and unevenly distributed in Passeriformes), they are not required by present theories to have been distinct in the Mesozoic. As unequivocal Passeriformes are known from Australia some 55 Mya, the acanthisittids' ancestors likely arrived in the Late Paleocene from Australia or the then-temperate Antarctic coasts. Plate tectonics indicate that the shortest distance between New Zealand and those two continents was roughly 1,500 km (1,000 miles) at that time. New Zealand's minimum distance from Australia is a bit more today – some 1,700 km/1,100 miles - whereas it is now at least 2,500 km (1,550 miles) from Antarctica.

A Kentish Plover nest, with a standard grey card Kentish plovers either nest solitarily or in a loose semicolonial manner. They are ground-nesting birds that lay their eggs in small shallow scrapes prepared by the male during courtship on the bare ground. Selection of the breeding ground is essential for the survival of nests and broods; nests are placed near the water on bare earth or in sparse vegetation; often on slightly elevated sites in order to have a good view of the surroundings to spot predators from a distance or near small bushes, plants or grass clusters,Snow, D.W. and Perrins, C.M. 1998.

In Korea, the mallard and the similar spot- billed duck (Anas poecilorhyncha) made up 38.1% of the biomass. Other recorded bird species in the Eurasian eagle-owl's diet includes all type of birds found in their range, including bustards, sandgrouse, parrots, cuckoos, swifts, the hoopoe (Upupa epops), the European bee-eater (Merops apiaster), the common kingfisher (Alcedo atthis), the European roller (Coracias garrulus), at least seven species of woodpecker (from the smallest to the largest European species) and more than 80 species of passerine. Among passerines, the only family reported widely as prey besides corvids are thrushes. In the Italian Alps, Turdus species were the fourth most frequently recorded type of prey.

The taxonomy of the finch family, in particular the cardueline finches, has a long and complicated history. The study of the relationship between the taxa has been confounded by the recurrence of similar morphologies due to the convergence of species occupying similar niches. In 1968 the American ornithologist Raymond Andrew Paynter Jr. wrote: > Limits of the genera and relationships among the species are less understood > – and subject to more controversy – in the carduelines than in any other > species of passerines, with the possible exception of the estrildines > [waxbills]. Beginning in around 1990 a series of phylogenetic studies based on mitochondrial and nuclear DNA sequences resulted in substantial revisions being made to the taxonomy.

Like all Australian robins, the rose robin is not closely related to either the European robin or the American robin, but belongs rather to the Corvida parvorder comprising many tropical and Australian passerines, including pardalotes, fairywrens and honeyeaters, as well as crows. It belongs to the genus Petroica, whose Australian members are known colloquially as "red robins" as distinct from the "yellow robins" of the genus Eopsaltria. It was first described by ornithologist John Gould in 1840, with its specific epithet derived from the Latin roseus 'pink'. Testing of the nuclear and mitochondrial DNA of Australian members of the genus Petroica suggests that the rose and pink robins are each other's closest relative within the genus.

The eye of a bird most closely resembles that of the reptiles. Unlike the mammalian eye, it is not spherical, and the flatter shape enables more of its visual field to be in focus. A circle of bony plates, the sclerotic ring, surrounds the eye and holds it rigid, but an improvement over the reptilian eye, also found in mammals, is that the lens is pushed further forward, increasing the size of the image on the retina.Sinclair (1985) 88–100 Visual fields for a pigeon and an owl Eyes of most birds are large, not very round and capable of only limited movement in the orbits, typically 10-20° (but in some passerines, >80°) horizontally.

Female (left) and male common pheasants: Sexual dimorphism is conspicuous in this species, one of the most apomorphic gamefowl They are chicken-like in appearance, with rounded bodies and blunt wings, and range in size from small at 15 cm (6 inches) to large at 120 cm (4 feet). They are mainly terrestrial birds and their wings are short and rounded for short-distance flight. Galliforms are anisodactyly like passerines, but some of the adult males grow spurs that point backwards. Gallinaceous birds are arboreal or terrestrial animals; many prefer not to fly, but instead walk and run for locomotion. They live 5–8 years in the wild and up to 30 years in captivity.

However, they will also prey on birds slightly larger than the passerines typically targeted, especially ptarmigan (Lagopus ssp.), as well as waterfowl, shorebirds (such as ruffs (Philomachus pugnax)) and short-eared owls (Asio flammeus). They usually target bird prey which are young and inexperienced, with relatively large avian prey often being snatched in their fledging stage. When small mammals are scarce, the rough-legged hawk will also feed on larger, medium-sized mammals including prairie dogs (Cynomys ssp.), ground squirrels, muskrats (Ondatra zibethicus), weasels (Mustela ssp.) and even adult black-tailed jackrabbits (Lepus californicus) of approximately twice their own weight. During winter, shrub-steppe habitats seem to encourage a strong dependence on rabbit prey.

Pale-billed flowerpecker Dicaeum erythrorhynchos with a Muntingia calabura berry (Hyderabad, India) Thick-billed flowerpecker Dicaeum agile on Helicteres isora Dicaeum is a genus of birds in the flowerpecker family Dicaeidae, a group of passerines tropical southern Asia and Australasia from India east to the Philippines and south to Australia. The genus is closely related to the genus Prionochilus and forms a monophyletic group. Its members are very small, stout, often brightly coloured birds, 10 to 18 cm in length, with short tails, short thick curved bills and tubular tongues. The latter features reflect the importance of nectar in the diet of many species, although berries, spiders and insects are also taken.

The flicker in particular is a highly numerous species that has similar habitat preferences to red-tailed hawks, preferring fragmented landscapes with trees and openings or parkland-type wooded mosaics, and often forage on the ground for ants, which may make them even more susceptible. Varied other woodpecker species may turn up in their foods, from the smallest to the largest extant in North America, but are much more infrequently detected in dietary studies. Another family relatively often selected prey family are corvids, which despite their relatively large size, formidable mobbing abilities and intelligence are also slower than average fliers for passerines. 14 species of corvid are known to fall prey to red- tailed hawks.

Consequently, the spot-winged tit might have to be included in P. ater, or some coal tits could be considered a distinct species. As occasional hybridization has been recorded between the two, mtDNA alone (which is inherited only from the mother) is insufficient to determine whether hybrid gene flow or another trivial cause (such as incomplete lineage sorting) obfuscates the actual relationships, or whether taxonomic rearrangement is indeed required. With the range of these titmice encircling the Himalayas, without further study it cannot even be excluded that they constitute a ring species – with gene flow occurring in Nepal but not in Afghanistan – as has been shown for other passerines in the same region.

Ruby-throated hummingbird (Archilochus colubris) at scarlet beebalm flowers (Monarda didyma) The main families of specialized nectar feeding birds that are involved in ornithophily are the hummingbirds (Trochilidae), sunbirds (Nectariniidae), and the honey-eaters (Meliphagidae). Other important bird groups include those in the families the Icteridae, the honeycreepers (Thraupidae, Drepanidae), white- eyes (Zosteropidae) and the South African sugar-birds (Promeropidae). Birds may obtain nectar either by perching or by hovering with the latter mainly found in the hummingbirds and sunbirds. Within the hummingbirds, two kinds of foraging are noted with territorial "hermit" hummingbirds and the non-hermits which forage longer distances Hummingbirds have the ability to digest sucrose unlike many passerines that prefer hexoses (fructose and glucose).

The Accipitriformes (from Latin accipiter "hawk" + New Latin -iformes "like") are an order of birds that includes most of the diurnal birds of prey – including hawks, eagles, and kites, but not falcons. For a long time, the majority view was to include them with the falcons in the Falconiformes, but many authorities now recognize a separate Accipitriformes. A DNA study published in 2008 indicated that falcons are not closely related to the Accipitriformes, being instead more closely related to parrots and passerines. Since then, the split and the placement of the falcons next to the parrots in taxonomic order has been adopted by the American Ornithological Society's South American Classification Committee (SACC), its North American Classification Committee (NACC), and the International Ornithological Congress (IOC).

In Amsterdamse-Waterleidingduinen area of the Netherlands, birds tended to dominate the biomass especially medium-sized passerines such as common starlings and Eurasian jays (Garrulus glandarius), with these contributing 54% of the biomass in high Apodemus mouse years to 62.7% in low mouse years in March–May. Smaller birds such as birds decrease from 21.1 to 3.1% in the spring while large birds such as pigeons and Eurasian woodcocks (Scolopax rusticola) may increase from 16.2 to 37.7% during high and low years for mice. In a small study from Norway, a large portion of diet consisted of birds in summer (61% of the biomass but only 23.2% by number) while, in winter, voles almost completely dominated the foods. house and Eurasian tree sparrows, both pictured.

Their species include 56 of cartilaginous fishes and 386 of bony fishes. The 266 species of inland fishes belong to 61 families, of which Cyprinidae is the largest, having 61 species. There are also 55 species of catfishes found in the fresh waters of Bangladesh. The amphibians in Bangladesh include only the species of the order Anura. From the 22 amphibian species, 8 are recognized as threatened. The number of reptiles species found is 126 which includes 109 inland and 17 marine species. From the 109 inland reptiles, 2 are crocodilians, 21 turtles and tortoises, 18 lizards, and 67 snakes. The marine reptiles comprise 12 snakes and 5 turtles. There are 628 species of birds found in Bangladesh under 16 orders and 67 families, including 276 passerines.

Numerous bird species can be sighted in Pinellas, either as permanent residents or during the winter migration, including wading birds like great blue herons, egrets, white ibises and roseate spoonbills, aquatic birds like brown pelicans, white pelicans, and cormorants, numerous species of shorebirds, and very-common birds like seagulls and passerines like the blue jay, mockingbird, and crow. Ospreys are a commonly seen bird-of-prey, with other birds of prey like turkey vultures, red tailed hawks, great horned owls, screech owls, barn owls, and bald eagles, among others, seen as well. Gopher tortoises are found in many areas, the burrows they dig making them a keystone species. Coyotes, though often associated with the American West, are native- to and can be found in Pinellas.

The lyrebird's syrinx is the most complexly-muscled of the passerines (songbirds), giving the lyrebird extraordinary ability, unmatched in vocal repertoire and mimicry. Lyrebirds render with great fidelity the individual songs of other birds and the chatter of flocks of birds, and also mimic other animals such as koalas and dingoes. The lyrebird is capable of imitating almost any sound and they have been recorded mimicking human sounds such as a mill whistle, a cross-cut saw, chainsaws, car engines and car alarms, fire alarms, rifle-shots, camera shutters, dogs barking, crying babies, music, mobile phone ring tones, and even the human voice. However, while the mimicry of human noises is widely reported, the extent to which it happens is exaggerated and the phenomenon is unusual.

The three species contained in the family have been moved around between different families for fifty years, including the Colluricinclidae (shrike-thrushes), Falcunculidae (shrike-tits) and Pachycephalidae (whistlers). A series of studies of the DNA of Australian birds between 2006 and 2001 found strong support for treating the three genera as a new family, which was formally named in 2016 (although the name had first been proposed by Sibley and Ahlquist in 1985) . Within the passerines the relationship of the Australo-Papuan bellbirds to other bird families has been difficult to establish, at one time they have been thought to be close to a range of families including the cuckoo-shrikes, whistlers, false-whistlers (Rhagologidae), crested berrypeckers, butcherbirds and woodswallows, and Old World orioles.

Although their typical lifespan is considerably shorter, common ravens can live more than 23 years in the wild, which among passerines only is surpassed by a few Australian species such as the satin bowerbirdAustralian Bird and Bat Banding Scheme Satin Bowerbird and probably the lyrebirds. Young birds may travel in flocks but later mate for life, with each mated pair defending a territory. Common ravens have coexisted with humans for thousands of years and in some areas have been so numerous that people have regarded them as pests. Part of their success as a species is due to their omnivorous diet: they are extremely versatile and opportunistic in finding sources of nutrition, feeding on carrion, insects, cereal grains, berries, fruit, small animals, nesting birds, and food waste.

The willie wagtail is unrelated to the Eurasian wagtails of the family Motacillidae. It is one of 47 members of the fantail genus Rhipidura; some authorities classify this group of birds as a subfamily Rhipidurinae within the drongo family Dicruridae, together with the monarch flycatchers, while others consider them distinct enough to warrant their own family Rhipiduridae. Early molecular research in the late 1980s and early 1990s revealed that the fantails belong to a large group of mainly Australasian birds known as the parvorder Corvida comprising many tropical and Australian passerines. More recently, the grouping has been refined somewhat and the fantails have been classified in a "core corvine" group with the crows and ravens, shrikes, birds of paradise, monarch flycatchers, drongos and mudnest builders.

In North America, prey has varied in size from hummingbirds (Selasphorus and Archilochus ssp.) to a sandhill crane (killed in Alaska by a peregrine in a stoop), although most prey taken by peregrines weigh from (small passerines) to (such as ducks and gulls). The peregrine falcon takes the most diverse range of bird species of any raptor in North America, with more than 300 species having fallen victim to the falcon, including nearly 100 shorebirds. Smaller hawks and owls are regularly predated, mainly smaller falcons such as the American kestrel, merlin and sharp-shinned hawks. In urban areas, the main component of the peregrine's diet is the rock or feral pigeon, which comprise 80% or more of the dietary intake for peregrines in some cities.

Other animals such as cotton rats, snakes, frogs, arthropods (especially grasshoppers, cicadas and beetles), and smallish birds such as passerines or quails are also eaten; it will snatch chickens when no other source of food is available. In the open cerrado of Brazil, mixed-species feeding flocks will react to a white-tailed hawk with almost as much alarm as they do when seeing such dedicated predators of birds as the aplomado falcon.Ragusa-Netto (2000) The white-tailed hawk is also known to feed on carrion and to gather with other birds at brushfires to catch small animals fleeing the flames.eNature (2007), HCT (2008) In the tropics, white- tailed hawks rank amongst the main predators of the small monkeys known as marmosets.

Cup nest of a common blackbird Small bird species in more than 20 passerine families, and a few non-passerines—including most hummingbirds, kinglets and crests in the genus Regulus, some tyrant flycatchers and several New World warblers—use considerable amounts of spider silk in the construction of their nests. The lightweight material is strong and extremely flexible, allowing the nest to mold to the adult during incubation (reducing heat loss), then to stretch to accommodate the growing nestlings; as it is sticky, it also helps to bind the nest to the branch or leaf to which it is attached. Many swifts and some hummingbirds use thick, quick-drying saliva to anchor their nests. The chimney swift starts by dabbing two globs of saliva onto the wall of a chimney or tree trunk.

Nest Record and Dietary Items for the Black Hawk-Eagle (Spizaetus tyrannus) from the Yucatan Peninsula. Journal of Raptor Research, 27 (2):121-122. Meanwhile, black-and-white hawk-eagles have been indicated to show a preference for slightly smaller birds than those selected by ornate hawk-eagles, such as medium-to-large passerines, pigeons and smallish toucans (such as aracaris and toucanets), though capable of preying on adult ducks and even monkeys quite as large as those taken by the ornate. The most similar hawk-eagle by diet is the closely related black-and- chestnut eagle, as this often hunts gamebirds such as cracids and procyonids like the ornate, but this species has a different altitudinal range being found in forests in the high montane forests, usually at a minimum elevation of .

They are called "wrens" due to similarities in appearance and behaviour to the true wrens (Troglodytidae), but are not members of that family. New Zealand wrens are mostly insectivorous foragers of New Zealand's forests, with one species, the New Zealand rock wren, being restricted to alpine areas. Both the remaining species are poor fliers and four of the five extinct species are known to be, or are suspected of having been, flightless (based on observations of living birds and the size of their sterna); along with the long-legged bunting from Tenerife, one of the Canary Islands, they are the only passerines known to have lost the ability to fly. Of the species for which the plumage is known, they are drab-coloured birds with brown-green plumage.

It is possible to select standard species of forminifera from sections through the sediment column, and by mapping the variation in oxygen isotopic ratio, deduce the temperature that the Forminifera encountered during life if changes in the oxygen isotopic composition of the water can be constrained. Paleotemperature relationships have also enabled isotope ratios from calcium carbonate in barnacle shells to be used to infer the movement and home foraging areas of the sea turtles and whales on which some barnacles grow. In ecology, carbon and nitrogen isotope ratios are widely used to determine the broad diets of many free-ranging animals. They have been used to determine the broad diets of seabirds, and to identify the geographical areas where individuals spend the breeding and non- breeding season in seabirds and passerines.

They at times will make use of manmade perches in suburban areas, such as utility poles, peaked roofs, chimney pots, tall fences, billboards or television antenna by dusk, while during the day they often tuck away in hollies, evergreens, oaks and/or thick ivy. On occasion, they may found roosting even in the attics of large buildings, barns or sheds, inside church towers or the chimneys of houses. One may be able to locate tawny owls by looking for whitewash but, unlike long- eared owls, tawny owls changes perch sites with some regularity so they tend to be less detectable overall. Often finding tawny owls during daylight is done by listening for noisy mobbing of a discovered owl by other birds, especially by large and/or bold passerines, or by squirrels during the day.

Scotland's position on the western seaboard of Europe means that a variety of birds not normally found in the country visit from time to time. These include accidental visits by vagrant birds that have wandered far from their normal habitations. Fair Isle is an internationally renowned site for the observation of migrant birds. Rarities have included passerines such as the thick-billed warbler, white-throated sparrow, yellow- rumped warbler and collared flycatcher. More than 345 species of bird have been recorded on this island, which measures only .Haswell-Smith (2004) p. 410. Elsewhere, other rarities reported in 2006 include a white-billed diver at Gairloch, a black-browed albatross in the Western Isles, a laughing gull in Shetland and a buff-breasted sandpiper at Lossiemouth.British Birds (August 2006) 199.

These studies indicated that the barred owl may snatch passerines of any age, but recent fledglings are taken preferentially due to their more conspicuous behavior and limited ability to fly away. In Minnesota, about 62% of studied hermit thrush and ovenbird fledglings were taken per one study, with all thrush that nested in the radius of the barred owl’s nests failing to produce any young. A similarly high rate of local determent by barred owls has been found for other woodland thrushes like the veery, wood thrush and varied thrush, with the additional finding that pre-dawn singing by certain thrushes, when their escape abilities are dulled by the dim light, leaves them vulnerable to barred owl ambushes.Gill, R. A., Cox, W. A., & Thompson III, F. R. (2016).

Illustration of an adult and a juvenile by Joseph Smit (1875) The Indian spotted eagle was earlier considered as the resident of eastern subspecies of the lesser spotted eagle but has proven quite distinct and readily separable by morphological, behavioral, ecological and DNA sequence data. The Indian lineage seems to have diverged around the middle Pliocene, perhaps some 3.6 million years ago,The estimate in Väli (2006) is certainly incorrect; it uses a molecular clock that is appropriate for small passerines with half the generation times of eagles. from the common ancestor of the lesser and greater spotted eagles. The "proto- spotted eagle" probably lived in the general region of Afghanistan, being split into a northern and a southern lineage when both glaciers and deserts advanced in Central Asia as the last ice age began.

The yellow- throated euphonia is one of 27 species of the genus Euphonia, which includes arboreal passerines restricted to the Neotropics. Euphoniinae are characterized by the absence of a gizzard associated with a highly specialized frugivorous diet and the construction of domed globe-shaped nests with a side entrance. Euphonias exhibit sexual dimorphism where males are dark iridescent blue in their upperparts and yellow on their ventral side, and females are typically olive-colored above and either yellow or gray below. The genus Euphonia is paraphyletic with Chlorophonia nested in it and was traditionally considered part of Thraupinae, however recent phylogenetic analysis using mitochondrial DNA demonstrated that Euphonia and Chlorophonia formed a monophyletic group distinct from the rest of the Thraupinae, which agrees with morphological and behavioral differences between Euphonia and Chlorophonia and the Tanagers.

The typical eagles are often united with the buteos (Buteo), sea eagles (Haliaetus) and other more heavy-set Accipitridae, but they may be less distinct than formerly believed from the more slender accipitrine hawks. The lesser spotted eagle is the greater spotted eagle's closest living relative; their common ancestor seems to have diverged around the middle Pliocene, perhaps some 3.6 million years ago (mya),The estimate in is certainly incorrect; it uses a molecular clock that is appropriate for small passerines with half the generation times of eagles. from the ancestors of the Indian spotted eagle that lives in a band from Iran to and India.

However, the ornate hawk-eagle is far from specialized on cracid prey and takes more or less any medium-sized or larger avian prey they opportune upon. In total, about 65% of recorded prey species for ornate hawk-eagles are birds. Beyond cracids, some of the most significant prey families and orders are tinamou (at least 8 species), pigeons and doves (9 species or more), toucans (at least 7 species), parrots (at least 9 species) as well as assorted non-cracid gamebirds and largish passerines. In Tikal, Guatemala, the most often identified avian prey on 10 ornate hawk-eagle territories was the keel-billed toucan (Ramphastos sulfuratus), accounting for 11.3% of 408 prey items, followed by the plain chachalaca (Ortalis vetula) (6.5%) and great tinamou (Tinamus major) (4%) (in by far the largest dietary study conducted for this hawk-eagle).

Jamieson, I. (2015) "Significance of population genetics for managing small natural and reintroduced populations in New Zealand". New Zealand Journal of Ecology 39 (1): 1–18 The specialised nesting habitat of the orange-fronted parakeet increases its vulnerability to extinction. The reasons for this include: (1) a single nest opening means that incubating females may be unable to escape from invading predators and will also be killed, (2) because only females incubate, predation may cause a biased sex ratio, (3) their relatively long nesting period (when compared to other passerines) increases their vulnerability to predation, and (4) the chicks tend to be noisy and therefore more attractive to predators. Furthermore, in beech silviculture the trees are not given enough time to develop adequate hollows before they are harvested, thereby reducing the number of suitable nesting sites in managed beech forests.

Common and thick-billed murres (Uria aalge and U. lomvia, respectively) dominated the diet around the Sea of Okhotsk, followed by black-legged kittiwakes (Rissa tridactyla), slaty-backed gulls, crested auklets (Aethia cristatella), and pelagic cormorants (Phalacrocorax pelagicus). Small chicks of murres and cormorants were sometimes taken alive in Russia and brought back to nests, where they independently fed on remains of fish in the eagles' nests until they were killed themselves. In Russia, upland grouse, such as black-billed capercaillie (Tetrao parvirostris) and willow and rock ptarmigan (Lagopus lagopus & L. muta) can be an important prey species; grouse are not typically taken by other Haliaeetus species. Other landbirds hunted by Steller's sea eagles have included short-eared owls (Asio flammeus), snowy owl (Bubo scandiaca), carrion crow (Corvus corone) and common raven (Corvus corax), as well as (rarely) smaller passerines.

Bathornis is the type genus of Bathornithidae, a family of Cariamiformes, related to the modern seriemas (this relationship has been recognised ever since its first description) and also a variety of extinct forms like phorusrhacids, Strigogyps and idiornithids, in turn part of the Australaves assemblage that also includes falcons, passerines and parrots. Interspecific relations within the Cariamiformes are highly volatile and unresolved, bathornithids at times having been listed as sister taxa to seriemas, phorusrhacids and idiornithids, sometimes even as a polyphyletic group. It is usually considered the sister clade to Paracrax, and several authorities consider Neocathartes and several other taxa to be nested with it (see below). However, at least one phylogenetic study recovers Bathornis (and its synonyms) as more closely related to phorusrhacids than to Paracrax, though this is considered premature and based on far too few synapomorphies.

Hooded crow (Corvus cornix) in flight Jungle crow (Corvus macrorhynchos) scavenging on a dead shark at a beach in Kumamoto, Japan Medium-large species are ascribed to the genus, ranging from 34 cm of some small Mexican species to 60–70 cm of the large common raven and thick-billed raven, which together with the lyrebird represent the larger passerines. These are birds with a robust and slender appearance, equipped with a small rounded head with a strong conical beak, elongated and pointed, with a slightly curved end towards the bottom: the legs are strong and the tail is short and wedge-shaped . The coloration of the livery is dominated by shades of black, with some species having plumage with metallic iridescences and others that have white or gray areas on the neck or torso: Australian species have light eyes, while generally the irises are dark. Sexual dimorphism is limited.

A male common chaffinch About half of the European birds are passerines of the songbirds suborder. The more common of these include larks (skylark, crested lark, woodlark), swallows (barn swallow, sand martin, house martin), Motacillidae (tree pipit, meadow pipit, white wagtail, yellow wagtail), shrikes (red-backed shrike, great grey shrike), golden oriole, European starling, crows (magpie, jackdaw, hooded crow, rook, Eurasian jay), white- throated dipper, dunnock, Eurasian wren, Eurasian nuthatch, goldcrest, several warblers (reed warbler, sedge warbler, great reed-warbler, icterine warbler, Cetti's warbler, garden warbler, blackcap, whitethroat, chiffchaff), Old World flycatchers (pied flycatcher, spotted flycatcher, northern wheatear, whinchat, European stonechat), finches (common chaffinch, goldfinch, siskin, Eurasian bullfinch, greenfinch, common crossbill, linnet), sparrows (house sparrow, tree sparrow), buntings, (corn bunting, ortolan bunting, reed bunting, yellowhammer), tits (great tit, blue tit, coal tit).Bruun B. & Singer A.

The taxonomy of the New Zealand wrens has been a subject of considerable debate since their discovery, although they have long been known to be an unusual family. In the 1880s, Forbes assigned the New Zealand wrens to the suboscines related to the cotingas and the pittas (and gave the family the name Xenicidae). Later, they were thought to be closer to the ovenbirds and antbirds. Sibley's 1970 study comparing egg-white proteins moved them to the oscines, but later studies, including the 1982 DNA-DNA hybridization study, suggested the family was a sister taxon to the suboscines and the oscines. This theory has proven most robust since then and the New Zealand wrens might be the survivors of a lineage of passerines that was isolated when New Zealand broke away from Gondwana 82–85 million years ago (Mya),Ericson P, Christidis L, Cooper, A, Irestedt M, Jackson J, Johansson US, Norman JA. (2002).

The waitoreke would be most remarkable if it exists, due to the fact that New Zealand is one of the few significant land masses on Earth to have no recent native land mammals. The South Pacific nation does play host to several native pinnipeds (seals, sea lions) and bat species (genera Mystacina and Chalinolobus; several extinct genera are known from the earlier Saint Bathans FaunaWorthy, Trevor; Hand, SJ; Worthy, TH; Archer, M; Worthy, JP; Tennyson, AJD; Scofield, RP (2013). "Miocene mystacinids (Chiroptera, Noctilionoidea) indicate a long history for endemic bats in New Zealand". Journal of Vertebrate Paleontology 33 (6): 1442–1448.) but is most notable for its plethora of bird species that seem to have evolved without the restrictions of mammalian predation: flightless species that would have been fair game for any hunting mammal were most plentiful, and there were even some tiny flightless passerines - a thing almost unheard of, and certainly unknown in the presence of mammalian predators as small as shrews.

1120-1132 the first detailed breeding studies conducted on Chiloé suggest each pair typically raises only a single clutch per year, and that reduction of clutches after laying by discarding eggs is not unknown, though brood reduction by this method has generally been exceptionally rarely seenMoreno, Juan; "Parental infanticide in birds through early eviction from the nest: rare or under-reported?" in Journal of Avian Biology, Volume 43, Issue 1 (January 2012); pp. 43–49 and thought to be absent from south temperate passerines. Growth of nestlings is distinctly slow: fledging lasts twenty-one days and postfledging parental care around thirty days. The latter is distinctly longer than in north temperate species at the same distance from the equator, but not nearly so long as in many tropical, Australian and southern African passerinesSee McMahon T.A. and Finlayson, B.; Global Runoff: Continental Comparisons of Annual Flows and Peak Discharges; where young are not independent for over sixty days.

A tabby cat and a mixed Molosser dog A pet, or companion animal, is an animal kept primarily for a person's company or entertainment rather than as a working animal, livestock or a laboratory animal. Popular pets are often considered to have attractive appearances, intelligence and relatable personalities, but some pets may be taken in on an altruistic basis (such as a stray animal) and accepted by the owner regardless of these characteristics. Two of the most popular pets are dogs and cats; the technical term for a cat lover is an ailurophile and a dog lover a cynophile. Other animals commonly kept include: rabbits; ferrets; pigs; rodents, such as gerbils, hamsters, chinchillas, rats, mice, and guinea pigs; avian pets, such as parrots, passerines and fowls; reptile pets, such as turtles, alligators, crocodiles, lizards, and snakes; aquatic pets, such as fish, freshwater and saltwater snails, amphibians like frogs and salamanders; and arthropod pets, such as tarantulas and hermit crabs.

In 1840, George Robert Gray proposed the name N. gouldii, arguing that neither of Gould's names was applicable to the species.Gray 1840:15 In 1850, Jean Cabanis replaced the name Neomorpha, which had been previously used for a cuckoo genus, with Heteralocha.Cabanis 1850–1851:218, footnote In 1888 Sir Walter Buller wrote: "I have deemed it more in accordance with the accepted rules of zoological nomenclature to adopt the first of the two names applied to the species by Mr Gould; and the name Neomorpha having been previously used in ornithology, it becomes necessary to adopt that of Heteralocha, proposed by Dr Cabanis for this form."Buller 1888:8 The huia appears to be a remnant of an early expansion of passerines in the country of New Zealand, and is the largest of the three members of the family Callaeidae, the New Zealand wattlebirds; the others are the saddleback and the kōkako.

On occasion, individual owls, especially inexperienced juveniles, will become habitual fowl killers. These errant owls mainly hunt chickens, though will also take domestic guineafowl, turkeys and anything else available. In general, chickens kept in locked cages with enclosed tops overnight are safe from great horned owls; not so chickens left free range or in open enclosures. While galliforms are widely reported, the few cases where great horned owls locally turn to birds as the primary food source over mammals, these may often be local responses to the abundance of breeding water birds or concentrations of roosting water birds, since they tend to roost in relatively open spots. They have been known to predate more than 110 different species of assorted water bird. In prairie wetlands of North Dakota, avian prey, primarily represented by ducks and the American coot (Fulica americana) came to represent 65% by number and 83% by biomass of the diet of the local owls, also including secondarily grebes, smaller rails and shorebirds as well as upland-based species like grey partridge (Perdix perdix), sharp-tailed grouse and passerines.

2002) but are not found in the Park. The area where they occur is now Deng Deng National Park. The first bird list for Mbam Djerem, a synthesis of the Fotso and Bobo/ Languy surveys, numbered 360 species, and, as for the mammal fauna, included both true savannah species such as brown-rumped bunting Emberiza affinis, black-bellied firefinch Lagonosticta rara, lesser blue-eared starling Lamprotornis chloropterus, white-collared starling Grafisia torquata, brubru Nilaus afer and yellow penduline tit Anthoscopus parvulus and true forest species such as some of the hornbills: black and white casqued hornbill Ceratogymna subcylindricus, black casqued hornbill Ceratogymna atrata, red-billed dwarf hornbill Tockus camurus, and passerines such as Bleda syndactyla, Bleda eximia, Alethe diademata, Stiphrornis erythrothorax Criniger Calurus, Indicator maculatus (Fotso 2000). The Bamenda Apalis Apalis bamendae was discovered to be relatively widespread throughout the area (Bobo & Languy 2000 a,b; Fotso 2000) - this bird had previously thought to have been restricted to a small area in the Bamenda Highlands of Northwest Cameroon, two hundred kilometres to the west of Mbam Djerem.
