Buteo is a genus of medium to fairly large, wide-ranging raptors with a robust body and broad wings. In the Old World, members of this genus are called "buzzards", but "hawk" is used in North America (Etymology: Buteo is the Latin name of the common buzzard). As both terms are ambiguous, buteo is sometimes used instead, for example, by the Peregrine Fund.

The two buzzards are aggressive towards one another and excluded each other from winter feeding territories in similar ways to the way they exclude conspecifics. In northern Germany, the buffer of their habitat preferences apparently accounted for the lack of effect on each other's occupancy between the two buzzard species.Sylven, M. (1978).

The common buzzard, in turn, is also part of a species complex with other Old World buzzards, namely the mountain buzzard (Buteo oreophilus), the forest buzzard (Buteo trizonatus ) and the Madagascar buzzard (Buteo brachypterus). All six species in the alleged species complex, although varying notably in size and plumage characteristics, that houses red-tailed hawk share with it the feature of the blackish patagium marking, which is missing in most other Buteos.

The -long honey buzzard is larger and longer winged, with a wingspan, when compared to the smaller common buzzard (Buteo buteo). It appears longer necked with a small head, and soars on flat wings. It has a longer tail, which has fewer bars than the Buteo buzzard, usually with two narrow dark bars and a broad dark subterminal bar. The sexes can be distinguished on plumage, which is unusual for a large bird of prey.
|
|
The first formal description of the common buzzard was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Falco buteo. The genus Buteo was introduced by the French naturalist Bernard Germain de Lacépède in 1799 by tautonymy with the specific name of this species. Page numbering starts at one for each of the three sections. The word buteo is Latin for a buzzard.

Other raptors, large and small, are often outright dominated by golden eagles. In Eurasia, the relative paucity of mid-sized Buteo species is thought to be due to the radiation of large Aquila eagles that already occupied the large raptor niche and outcompeted them. In North America, where there are no Aquila eagles other than the golden eagle, Buteo species are more diverse with at least 3 large hawks (the red-tailed, Swainson's (Buteo swainsoni) and ferruginous hawks (Buteo regalis)) that occur in similar habitats and sometimes eat similar prey as both each other and golden eagles. On occasion, golden eagles will kleptoparasitize or prey upon these three Buteos.

The mountain buzzard and the forest buzzard are said to form a superspecies with the common buzzard and the Madagascar buzzard Buteo brachypterus, and may be also with the red-tailed hawk Buteo jamaicensis of North and South America and the rufous-tailed hawk Buteo ventralis of southern South America. The mountain buzzard has been classified as a subspecies of common buzzard, then split as a single species with the forest buzzard but nor these two are regarded as separate species.

DNA testing shows that the common buzzard is fairly closely related to the red-tailed hawk (Buteo jamaicensis) of North America, which occupies a similar ecological niche to the buzzard in that continent. The two species may belong to the same species complex. Two buzzards in Africa are likely closely related to the common buzzard based on genetic materials, the mountain (Buteo oreophilus) and forest buzzards (Buteo trizonatus), to the point where it has been questioned whether they are sufficiently distinct to qualify as full species.

Ornithological Monographs, 992-999. More unlikely to be mistaken for a Cooper's hawk are some buteonine hawks such as gray hawks (Buteo plagiatus), roadside hawks (Rupornis magnirostris) (in Mexico and points south) and broad- winged hawks (Buteo platypterus) which are all similar in size to the Cooper's as well as the slightly larger red-shouldered hawk (Buteo lineatus). Even the most similar buteonine hawks have notably different proportions than a Cooper's hawk, possessing relatively much longer wings and a much shorter tail. Given reasonable views, all such species are fairly to extremely different in plumage even in juvenile form.

Juvenile The Galapagos hawk is similar in size to the red tailed hawk (Buteo jamaicensis) and the Swainson's hawk (Buteo swainsoni) of North America, but the size is variable across the islands as is recorded for many animals native to the Galapagos. They appear to be somewhat more heavily built than those well-known mainland species, and going on average weights, this species is the second heaviest Buteo in the Americas, behind only the ferruginous hawk. The Galapagos hawk can range from in length from beak to tail with a wingspan of .Del Hoyo, J., & Elliot, A. I SARGATAL, J. eds. 1994.

The former species was placed in Geranoaetus – also a monotypic genus – in 1844, while the black- and-white hawk-eagle had been moved out of Buteo and into Spizastur a few years earlier. Thus, the identical specific epithets never came into direct conflict until recently. But the black-chested eagle-buzzard's placement in a monotypic genus was always disputed, and several authors treated it in Buteo. However, they overlooked that Buteo melanoleucus was the original name of the black-and-white hawk-eagle and thus as a senior homonym could not be applied to the later-described species.

Sharp-shinned hawk (Accipiter striatus), Cooper's hawk (Accipiter cooperii), and broad-winged hawk (Buteo platypterus) have nested in forested habitat on the refuge. Northern goshawks (Accipiter gentilis) and red-tailed hawks (Buteo jamaicensis) nest in the area. During migration (primarily autumn), many raptors move through the refuge. Northern harriers are the only raptor species thought to breed in the estuarine communities of the refuge.

Sparrows, which are common in urban and rural areas, may serve as a food source for wild and domestic carnivores. N. caninum has also been detected in common buzzards (Buteo buteo) and magpies. The presence of birds in cattle pastures has been correlated to higher infection rates in cattle. Birds may be an important link in the transmission of N. caninum to other animals.

The reserve is a good place to look for slowworms (Anguis fragilis). It supports breeding turtle doves (Streptopelia turtur); and green woodpeckers (Picus viridis), which are fond of feeding on ants, are frequent.

The broad-winged hawk (Buteo platypterus) is a small hawk of the genus Buteo. During the summer, some subspecies are distributed over eastern North America, as far west as British Columbia and Texas; they then migrate south to winter in the Neotropics from Mexico south to southern Brazil. Other subspecies are all-year residents on Caribbean islands. As in most raptors, females are slightly larger than males.

Western jackdaws (Corvus monedula) are notably regular usurpers of this species' nest holes and a potential predator of eggs and small nestlings. A few of the larger birds of prey that can hunt in woodlands may prey on black woodpeckers. Among those recorded are Ural owls (Strix uralensis), Eurasian eagle-owls (Bubo bubo), northern goshawks (Accipiter gentilis), common buzzards (Buteo buteo) and golden eagles (Aquila chrysaetos).

Grondnest van Buizerd Buteo buteo op bruggetje. De takkeling, 11(3), 234–236. In the Italian Alps, 81% of 108 nests were on cliffs. The common buzzard generally lacks the propensity of its Nearctic counterpart, the red-tailed hawk, to occasionally nest on or near manmade structures (often in heavily urbanized areas) but in Spain some pairs recorded nesting along the perimeter of abandoned buildings.

They are the heaviest Buteos on average in eastern North America, albeit scarcely ahead of the larger winged rough-legged buzzard (Buteo lagopus), and second only in size in the west to the ferruginous hawk (Buteo regalis). Red-tailed hawks may be anywhere from the fifth to the ninth heaviest Buteo in the world depending on what figures are used. However, in the northwestern United States, ferruginous hawk females are 35% heavier than female red-tails from the same area. On average, western red-tailed hawks are relatively longer winged and lankier proportioned but are slightly less stocky, compact and heavy than eastern red-tailed hawks in North America.
|
|
Although often described as long winged, the proportional size of the wings is quite small and red-tails have high wing loading for a buteonine hawk. For comparison, two other widespread Buteo hawks in North America were found to weigh: for every square centimeter of wing area in the rough-legged buzzard (Buteo lagopus) and per square cm in the red- shouldered hawk (Buteo lineatus). In contrast, the red-tailed hawk weighed considerably more for their wing area: per square cm. As is the case with many raptors, the red-tailed hawk displays sexual dimorphism in size, as females are up to 25% larger than males.

The correct specific name for the black- chested eagle-buzzard when placed in Buteo, Buteo fuscescens, was reestablished in the mid-20th century for a short time more by accident than anything else; as most late-20th-century researchers argued for retaining Geranoaetus, this name was dismissed as erroneous and essentially forgotten. As the black-and-white hawk-eagle has not been placed in Buteo since long, Article 59.3 of the ICZN Code applies. According to this, a junior homonym replaced before 1961 is not rendered permanently invalid (as junior homonyms usually are) if "the substitute name is not in use" – which has been the case after Amadon's 1963 revision. Hence, in this case the scientific name Buteo melanoleucus can apply to the black-chested eagle-buzzard, even though the black-and-white hawk-eagle was described under exactly that name earlier, while the senior homonym melanoleucus still applies to the latter species when placed in Spizaetus according to the usual ICZN rules.

The white-throated hawk (Buteo albigula) is a bird of prey in the family Accipitridae, which includes the eagles, hawks and Old World vultures. In British usage, it would be called a buzzard rather than a true hawk. The white-throated hawk is a rather small Buteo, long. It lives in the Andes mountains of South America and ranges down to the coast in the O'Higgins region of Chile, preferring wooded areas.

It attracts a wide range of birds including marsh tit (Parus palustris), buzzard (Buteo buteo) and great spotted woodpecker (Dendrocopos major). The pasture is of a kind now rare in the area. In summer the site has a wide variety of flowers such as betony (Stachys), oxeye daisy (Leucanthemum vulgare) and heath spotted orchid (Orchidaceae). In late summer, it is covered with drifts of black knapweed (Centaurea) and devil's bit scabious (scabiosa).

This absence is proposed as a diagnostic feature. A study of accipitrid skeletons found procoracoid incisurae (as opposed to foramina) in some specimens of the eagles Aquila gurneyi and A. chrysaetos, but not in four other Aquila species. The notch was variably open or weakly ossified in Spizastur melanoleucos, Lophoaetus occipitalis, Spizaetus ornatus, and Stephanoaetus coronatus. Also the buteonine hawks Buteo brachyurus and B. hemilasius had incisurae, differing from 17 other Buteo species.

There is usually a distinctive black carpal patch and dark trailing edge to the wing. The rump and "trousers" are often dark or deep rufous. Plumage varies from ghostly pale individuals to very dark ones. Some plumages are almost similar to those of the steppe buzzard, the eastern subspecies of the common buzzard (Buteo buteo vulpinus), but long-legged buzzards have longer wings and are more like rough- legged buzzards or even a small Aquila eagle.

The onset of migratory movement for steppe buzzards back to the breeding grounds in southern Africa is mainly in March, peaking in the second week. Steppe buzzard molt their feathers rapidly upon arrival at wintering grounds and seems to split their flight feather molt between breeding ground in Eurasia and wintering ground in southern Africa, the molt pausing during migration.Herremans, M.

All Buteo species are to some extent opportunistic when it comes to hunting, and prey on almost any type of small animal as it becomes available to them. However, most have a strong preference for small mammals, mostly rodents. Rodents of almost every family in the world are somewhere preyed upon by Buteo species. Since many rodents are primarily nocturnal, most buteos mainly hunt rodents that may be partially active during the day, which can include squirrels and chipmunks, voles, and gerbils.

Effect of agro‐forestry and landscape changes on Common Buzzards (Buteo buteo) in the Alps: implications for conservation. Animal Conservation, 8(1), 17-25. The common buzzard and common kestrel are probably the most often selected diurnal raptors because they inhabit the edges most often hunted by the eagle-owls. Studies have shown that peregrine falcon experience lower productivity in areas where they nest closely to eagle-owls, as the eagle-owls pick off both nestlings and adults by night.

Only one sonogram has been made of B. socotraensis, and because of such a small sample size, this behavioural trait has not been included in its taxonomy. Its call is very similar to other species of the same genus, namely Buteo rufinus, B. buteo, and B. oreophilus . A key identifying characteristic of the species' call is the short period (<1 second) between calls. Its call has a frequency of 2.2 kHz, a similar but different frequency than other species in the same taxa.

The specific name teesa is derived from the name in Hindi. The species was described on the basis of specimens collected by James Franklin who placed it in the genus Circus along with the harriers. The name Butastur was used to indicate that it appeared to be intermediate in characters to the Buteo buzzards and Astur, an old name for the sparrowhawks. Molecular phylogeny studies suggest that the genus is a sister group of Buteo and its relatives within the subfamily Buteoninae.

The Djibouti spurfowl endemic and critically endangered bird species The bird species reported in the wildlife of Djibouti consists of 399 species including one endemic (native) species, eight globally threatened species, and two introduced species. Further details under categories of the endemic, critically endangered, endangered, near-threatened and vulnerable are elaborated. However, 26 species of raptors have been reported in the coastal ecoregion. Of these, the steppe buzzard (Buteo buteo vulpinus) and the steppe eagle (Aquila nipalensis) are most common.

Slower raptors like black and red kites (Milvus migrans & milvus), eastern imperial eagle (Aquila heliaca), common buzzard (Buteo buteo) and Australasian harrier (Circus approximans) tend to take the more easily caught fledglings or juveniles.Génsbøl (1984) pp. 67, 74, 162. While perched in groups by night, they can be vulnerable to owls, including the little owl (Athene noctua), long-eared owl (Asio otus), short-eared owl (Asio flammeus), barn owl (Tyto alba), tawny owl (Strix aluco) and Eurasian eagle-owl (Bubo bubo).

Extreme pale birds are largely whitish with variable widely spaced streaks or arrowheads of light brown about the mid-chest and flanks and may or may not show dark feather-centres on the head, wing-coverts and sometimes all but part of mantle. Individuals can show nearly endless variation of colours and hues in between these extremes and the common buzzard is counted among the most variably plumage diurnal raptors for this reason.Dittrich, W. (1985). Gefiedervariationen beim Mäusebussard (Buteo buteo) in Nordbayern.

Density and productivity of Common Buzzard Buteo buteo and goshawk Accipiter gentilis populations in Rogów, Central Poland. Acta Ornithologica, 32(2), 149–155. In contrast, the slightly larger counterpart of buzzards in North America, the red-tailed hawk (which is also slightly larger than American goshawks, the latter averaging smaller than European ones) are more similar in diet to goshawks there. Redtails are not invariably dominated by goshawks and are frequently able to outcompete them by virtue of greater dietary and habitat flexibility.

Eastern fox squirrels (Sciurus niger) may raid the tree holes being used by eastern screech owls, not only destroying or consuming the eggs, but also displacing the adult owls from the hole to use the hole for themselves. Adults have fewer predators, but larger species of owls do take them, since they have similar periods of activity. Larger owls known to have preyed on eastern screech owls have included great horned owls, barred owls (Strix varia), spotted owls (Strix occidentalis), long-eared owls (Asio otus), short- eared owls (Asio flammeus), and snowy owls (Bubo scandianus). Diurnal birds of prey may also kill and eat them, including Cooper's hawks (Accipiter cooperii), northern harriers (Circus cyaenus), red-tailed hawks (Buteo jamaciensis), red-shouldered hawk (Buteo lineatus) and rough-legged hawks (Buteo lagopus).

Wildlife abounds in the valley, particularly the water birds around the rivers and lakes, with Chew Valley Lake considered the third most important site in Britain for wintering wildfowl. In addition to the water birds including ducks, shoveller (Anas clypeata), gadwall (Anas strepera) and great crested grebes (Podiceps cristatus), a wide variety of other bird species can be seen. These range from small birds such as tits (Paridae) and wrens (Troglodytidae) to mistle thrush (Turdidae). Larger birds include woodpeckers (Picidae) and common buzzard (Buteo buteo).

Mountain avens (Dryas octopetala) an alpine species which survives on Helvellyn Mountain birds around Helvellyn include the raven (Corvus corax), which has now become common. Peregrine falcons (Falco peregrinus), buzzards (Buteo buteo) and ring ouzels (Turdus torquatus) have all bred in the immediate area. Skylarks (Alauda arvensis) and wheatears (Oenanthe oenanthe) are frequently encountered. At one time eagles (probably Aquila chrysaetos) soared over the mountain and bred on the steep cliffs above Red Tarn, but even in Wordsworth's day they had gone, having been persecuted to extinction.

The red-tailed hawk is a member of the genus Buteo, a group of medium-sized raptors with robust bodies and broad wings. Members of this genus are known as buzzards in Eurasia, but hawks in North America. Under current classification, the genus includes approximately 29 species, the second most diverse of all extant accipitrid genera behind only Accipiter. The buzzards of Eurasia and Africa are mostly part of the genus Buteo, although two other small genera within the subfamily Buteoninae occur in Africa.

In studies from Germany and Sweden, buzzards were found to be less disturbance sensitive than goshawks but were probably displaced into inferior nesting spots by the dominant goshawks. The exposure of buzzards to a dummy goshawk was found to decrease breeding success whereas there was no effect on breeding goshawks when they were exposed to a dummy buzzard.Krüger, O. (2002). Analysis of nest occupancy and nest reproduction in two sympatric raptors: common buzzard Buteo buteo and goshawk Accipiter gentilis. Ecography, 25(5), 523–532.Krüger, O. (2002).

Species that are neither endemic nor biome-restricted but that have restricted ranges or that can be more easily seen in Ethiopia than elsewhere in their range: Abyssinian Roller is an Ethiopian relative of Lilac-breasted Roller, which is an intra-tropical breeding migrant of south and east Africa, and of European Roller, an uncommon Palearctic passage migrant. Black-billed Barbet, Yellow-breasted Barbet and Grey-headed Batis are species from the Sahel and Northern Africa but also occur in Acacia woodlands in the area. The most regularly observed raptor birds in crop fields in Dogu’a Tembien are Augur buzzard (Buteo augur), Common Buzzard (Buteo buteo), Steppe Eagle (Aquila nipalensis), Lanner falcon (Falco biarmicus), Black kite (Milvus migrans), Yellow-billed kite (Milvus aegyptius) and Barn owl (Tyto alba). Birdwatching can be done particularly in exclosures and forests.

Flying at a falconry display at Palmitos Park, Canary Islands, Spain Its scientific name is Latinized Ancient Greek and means "black-and-white crane- eagle" or (if called Buteo melanoleucos) "black-and-white buzzard": Geranoaetus comes from Ancient Greek géranos (γέρανoς), "crane" + aetós (ἆετός), "eagle". The "crane" reference is due to its grey upper wings and its loud cries. The alternative genus name Buteo is simply the Latin term used for these hawks in Ancient Rome, translating as "buzzard" (in the European sense). melanoleucus is from Ancient Greek mélan- (μέλαν-), "black-" + leukós (λευκός), "white".

Mammalian Species, 46(913), 71-87. Occasionally, this species will pirate foods from other eagles (and other species of bird of prey), especially during winter, and also tandem hunts in pairs as well. The eastern imperial eagle is, like most active predators, an opportunist who exploits any prey they are capable of overpowering. Their prey spectrum is highly varied, including somewhere between 200 and 300 prey species, a total number of prey species only a bit short of the occasionally sympatric common buzzard (Buteo buteo) which may be 500 times more numerous overall.

A small buzzard and quite similar to the steppe buzzard Buteo buteo vulpinus, the migratory subspecies of the Palearctic common buzzard which winters over most of Africa. The adult has brown upperparts with paler underparts with heavy brown blotches on the breast, belly, flanks and underwing coverts. The underside of the flight feathers is barred with a distinct black band along the rear edge of the wing. The tail is brown above, light grey below and shows faint narrow bars which are broadest just before the tail tip.

Cooper's hawks (Accipiter cooperii) and red-tailed hawks tend to be most vulnerable, as they prefer the same wooded edges frequented by great horned owls. Other diurnal raptors may be attracted to more enclosed wooded areas, such as sharp-shinned hawks (Accipiter striatus) or zone-tailed hawks (Buteo albonotatus), or more open plain and meadow areas, such as Northern harriers (Circus hudsonius) and ferruginous hawks, but this is almost never a total insurance against predation as all of these are recorded prey.Stoleson, S. H., & Sadoti, G. (2010). Zone-tailed Hawk (Buteo albonotatus).

The Cosumnes River Preserve is also a habitat for many mammals, birds, fish, reptiles, and amphibians. Some of the larger mammals that live on the preserve include beavers(Castor canadensis), otters(Lontra canadensis), mountain lions(Puma concolor), and black-tailed deer(Odocoileus hemionus). Many smaller mammal species also exist within the preserve such as muskrats(Ondatra zibethicus), black-tailed jackrabbits(Lepus californicus), and raccoons(Procyon lotor). Many people traveling to the preserve will witness local bird species such as the red-tailed hawks(Buteo jamaicensis), swainson's hawks(Buteo swainsoni), Nuttall's woodpeckers(Picoides nuttallii).

The most renowned among the animal species living in the park are wolves, that became extinct in the area around 1850 because of the increased number of inhabitants of that period. They reappeared around 150 years later coming from the central Apennine at the end of the 20th century, and are now an habitual presence in the protected area. They mostly prey on roe and fallow deer, which have also reappeared in the park in the last decades. Birds of prey are well represented by Buteo buteo, Accipiter nisus, Falco tinnunculus and Pernis apivorus.

The only sparing factor is the temporal difference (the buzzard nesting later in the year than the eagle-owl) and buzzards may locally be able to avoid nesting near an active eagle-owl family.Schindler, S. (2002). Territoriality and habitat-use of wintering Common Buzzards (Buteo buteo) in Schleswig-Holstein, Germany (Doctoral dissertation, uniwien). As the ecology of the wintering population is relatively little studied, a similar very large owl at the top of the avian food chain, the Verreaux's eagle-owl (Bubo lacteus), is the only known predator of wintering steppe buzzards in southern Africa.

The common vole, or other related vole species at times, were the main foods as well in the Ukraine (17.2% of 146 prey items) ranging east to Russia in the Privolshky Steppe Nature Reserve (41.8% of 74 prey items) and in Samara (21.4% of 183 prey items). Other records from Russia and the Ukraine show voles ranging from slightly secondary prey to as much as 42.2% of the diet.

For example, clutch sizes were twice as large on average where rabbits were common (Moray) than were where they were rare (Glen Urquhart).Swan, G. (2011). Spatial variation in the breeding success of the common buzzard Buteo buteo in relation to habitat type and diet (Doctoral dissertation, Department of Life Sciences, Silwood Park, Imperial College London). In northern Ireland, an area of interest because it is devoid of any native vole species, rabbits were again the main prey. Here, lagomorphs constituted 22.5% of prey items by number and 43.7% by biomass.

Buteo is the type genus of the subfamily Buteoninae. Traditionally this subfamily also includes eagles and sea-eagles. Lerner and Mindell (2005) proposed placing those into separate subfamilies (Aquilinae, Haliaaetinae), leaving only the buteonine hawks/buzzards in Buteoninae.

In the Wisconsin data, the red-shouldered, the broad-winged and rough-legged hawks (Buteo lagopus) as well as the northern harrier, peregrine falcon (Falco peregrinus) and the American kestrel all had lower mean prey masses. Much farther south in Durango, Mexico, while there was overlap in the class of prey selected by Cooper's hawks with the other studied raptor species, American kestrels, red- tailed and zone-tailed hawks (Buteo albonotatus), there was minimal overlap in which prey species were usually selected, especially given the difference in habitat usage. Furthermore, in Durango, while Cooper's and the Buteo hawks all took appreciable numbers of adult cotton rats, kestrels selected only young cotton rats. In a study in western Maryland, Cooper's hawks used more mature woodland with a more developed understory and more extensive ground cover than the other woodland nesting hawks, the broad-winged and red-shouldered hawks.

The Eurasian eagle-owl predates the largest members of the most species-rich diurnal raptor genera: the northern goshawks from the genus Accipiter, the upland buzzards from the genus Buteo and the gyrfalcons (F. rusticolus) of the genus Falco. Additional large raptors, i.e. those that can average or more in body mass, taken as prey include osprey (Pandion haliaetus), the red kites (Milvus milvus), short-toed eagles (Circaetus gallicus), the greater spotted eagle (Clanga clanga), the lesser spotted eagle (Clanga pomarina), and the rough-legged buzzards (Buteo lagopus) and saker falcons (Falco cherrug), in both of which females average more than .

Golden eagles are readily distinguished by their brown plumage, paler than most other Aquila, and pale nape patch Size readily distinguishes this species from most other raptors when it is seen well. Most other raptors are considerably smaller. Buteo hawks, which are perhaps most similar to the golden eagle in structure among the species outside of the "booted eagle" group, are often counted among the larger very common raptors. However, a mid-sized Buteo is dwarfed by a golden eagle, as an adult female eagle has about double the wingspan and about five times the weight.

Snakes such as bullsnakes (Pituophis catenifer), rat snakes (Elaphe spp.) and garter snakes (Thamnophis spp.) have been reported eating eastern towhee eggs. Weasels (Mustela spp.) and blue jays (Cyanocitta cristata) are also likely nest predators. Several birds are known to prey on both young and adult eastern towhees, including northern goshawk (Accipiter gentilis), Broad-winged (Buteo platypterus), short-tailed (Buteo brachyurus), sharp-shinned (Accipiter striatus) and Cooper's hawks (Accipiter cooperii). Other predators include barred (Strix varia), short-eared (Asio flammeus) and eastern screech-owls (Megascops asio) and even the loggerhead shrike (Lanius ludovicianus), which is scarcely larger than a towhee.Ogden, J. C. 1974.

The ferruginous hawk (ferruginous = from Latin ferrum – iron, ferrugin-, iron rust, iron-rust color – reddish-brown), Buteo regalis (Latin, royal hawk), is a large bird of prey and belongs to the broad-winged buteo hawks. An old colloquial name is ferrugineous rough-leg, due to its similarity to the closely related rough-legged hawk (B. lagopus). This species is a large, broad-winged hawk of the open, arid grasslands, prairie and shrub steppe country; it is endemic to the interior parts of North America. It is used as a falconry bird in its native ranges also high above land.

The red-tailed hawk (Buteo jamaicensis) is a bird of prey that breeds throughout most of North America, from the interior of Alaska and northern Canada to as far south as Panama and the West Indies. It is one of the most common members within the genus of Buteo in North America or worldwide. The red-tailed hawk is one of three species colloquially known in the United States as the "chickenhawk", though it rarely preys on standard-sized chickens. The bird is sometimes also referred to as the red-tail for short, when the meaning is clear in context.

In the south eastern part of the site is an extensive area of wild cherry (Prunus avium) and ash with a hawthorn (Crataegus monogyna) and hazel understorey. The variety of soils give rise to a similarly diverse ground flora which includes bluebell (Hyacinthoides non-scripta), great butterfly orchid (Platanthera chlorantha) and common spotted-orchid (Dactylorhiza fuchsii), stinking iris (Iris foetidissima) and spurge laurel (Daphne laureola). The woods have a rich fauna which includes fallow deer (Dama dama). They provide an excellent habitat for birds that breed in woodland such as buzzard (Buteo buteo), great spotted woodpecker (Dendrocopos major) and tree creeper (Certhia familiaris).

A falconer's red-tailed hawk (Buteo jamaicensis) The genus Buteo, known as "hawks" in North America and not to be confused with vultures, has worldwide distribution but is particularly well represented in North America. The red-tailed hawk, ferruginous hawk, and rarely, the red- shouldered hawk are all examples of species from this genus that are used in falconry today. The red-tailed hawk is hardy and versatile, taking rabbits, hares, and squirrels; given the right conditions it can catch geese, ducks, pheasants, and even wild turkeys. The red-tailed hawk is also considered a good bird for beginners.

Townsend's ground squirrels are the primary prey of ferruginous hawks (Buteo regalis) in the Great Basin and Columbia Plateau. They are also a major and often primary diet item of prairie falcons (Falco mexicanus). The Townsend's ground squirrel has been rated one of the two most important prey species in southeastern Idaho because of its importance to ferruginous hawks and prairie falcons. Other important predators of Townsend's ground squirrels include other hawks (Accipiter and Buteo spp.) and falcons (Falco spp.), common crows (Corvus corax), badgers (Taxidea taxus), coyotes (Canis latrans), long-tailed weasels (Mestrela frenata), western rattlesnakes (Crotalus viridis), and gopher snakes (Pituophis melanoleucus).

More difficult to identify among adult red-tails are its darkest variations, as most species of Buteo in North America also have dark morphs. Western dark morph red-tails (i.e. calurus) adults, however, retain the typical distinctive brick-red tail which other species lack, which may stand out even more against the otherwise all chocolate brown-black bird. Standard pale juveniles when perched show a whitish patch in the outer half of the upper surface of the wing which other juvenile Buteo lack. The most difficult to identify stages and plumage types are dark morph juveniles, Harlan’s hawk and some Krider’s hawks (the latter mainly with typical ferruginous hawks as aforementioned).

Later, habitat destruction, capture of immature individuals for the pet industry, hunting and predation contributed to the sharp population decline. The clearing of mature forests for agricultural development is the main reason for the decline of population. Natural predators of the Puerto Rican amazon include the red-tailed hawk (Buteo jamaicensis), the broad-winged hawk (Buteo platypterus), the peregrine falcon (Falco peregrinus) and the pearly-eyed thrasher (Margarops fuscatus). The thrasher invaded Puerto Rico in the mid-20th century and has been a problem for the parrot population since 1973; to combat this, specially designed deep nests were prepared for the parrots in subsequent years to prevent competition from the invaders.

The Buteoninae subfamily originated from and is most diversified in the Americas, with occasional broader radiations that led to common buzzards and other Eurasian and African buzzards. The common buzzard is a member of the genus Buteo, a group of medium-sized raptors with robust bodies and broad wings. The Buteo species of Eurasia and Africa are usually commonly referred to as "buzzards" while those in the Americas are called hawks. Under current classification, the genus includes approximately 28 species, the second most diverse of all extant accipitrid genera behind only Accipiter.

The forest buzzard (Buteo trizonatus), is a species of bird of prey found in Africa, though some authorities have placed it as a subspecies of another species, the mountain buzzard, Buto oreophilus. This is a resident breeding species in woodlands in southern and eastern South Africa.

However, genetic analyses indicate it is related to a grouping of Neophron–Gypaetus–Eutriorchis (Egyptian vulture, bearded vulture (lammergeier), and Madagascan serpent eagle). The fish eagles have a close genetic relationship with Haliastur and Milvus; the whole group is only distantly related to the Buteo group.

At one time, the rufous-tailed hawk (Buteo ventralis), distributed in Patagonia and some other areas of southern South America, was considered part of the red-tailed hawk species. With a massive distributional gap consisting of the majority of South America, the rufous-tailed hawk is considered a separate species now but the two hawks still compromise a "species pair" or superspecies, as they are clearly closely related. The rufous-tailed hawk, while comparatively little studied, is very similar to the red-tailed hawk, being about the same size in body mass and possessing the same wing structure, and having more or less parallel nesting and hunting habits. Physically, however, rufous-tailed hawk adults do not attain a bright brick-red tail as do red-tailed hawks, instead retaining a dark brownish- cinnamon tail with many blackish crossbars similar to juvenile red-tailed hawks. Another, more well-known, close relative to the red-tailed hawk is the common buzzard (Buteo buteo), which has been considered as its Eurasian “broad ecological counterpart” and may too be within a species complex with red- tailed hawk.

Lerner and Mindell (2005) found R. sociabilis sister to Geranospiza caerulescens, and that those two along with Ictinea plumbea were basal to both the buteogallus and buteo clades. They concluded that Rostrhamus belonged in Buteoninae (sensu stricto) and not in Milvinae, but noted that more investigation was needed.

Elsewhere, the Spanish imperial eagle and eagle-owl are considered to outflank the golden and even the Bonelli's eagle as the most specialized avian predator of rabbits in the Iberian region. Other predators, such as common buzzard (Buteo buteo), northern goshawk (Accipiter gentilis) black kite (Milvus migrans) Iberian wildcat (Felis silvestris tartessia), red fox, stone marten (Martes foina) and introduced Egyptian mongoose also prey heavily on rabbits in Spain, but are more generalized and less reliant than the above predators.Gil-Sanchez, J.

Specialist heathland birds are widespread, including Dartford warbler (Silvia undata), woodlark (Lullula arborea), northern lapwing (Vanellus vanellus), Eurasian curlew (Numenius arquata), European nightjar (Caprimulgus europaeus), Eurasian hobby (Falco subbuteo), European stonechat (Saxicola rubecola), common redstart (Phoenicurus phoenicurus) and tree pipit (Anthus sylvestris). As in much of Britain common snipe (Gallinago gallinago) and meadow pipit (Anthus trivialis) are common as wintering birds, but in the Forest they still also breed in many of the bogs and heaths respectively. Woodland birds include wood warbler (Phylloscopus sibilatrix), stock dove (Columba oenas), European honey buzzard (Pernis apivorus) and northern goshawk (Accipiter gentilis). Common buzzard (Buteo buteo) is very common and common raven (Corvus corax) is spreading.

Of the sedentary bird species the hawk (Buteo buteo rothschild) is the most notable, along with the Atlantic canary (Serinus canaria), common House Sparrow (Passer domesticus), Rock Dove (Columba livia), Atlantic European Goldfinch (Carduelis carduelis parva) and the Azorean subspecies of Common blackbird (Turdus merula azorensis). Migratory and marine birds are more common in the islands of the Azores, resulting in the identification of several species including approximately 37 nesting species on Monte Brasil annually (28 land and eight marine species). During the summer, and especially along the mount's southern coast there are large bands of nesting species of Cory's Shearwater (Calonectris diomedea), Common Tern (Sterna hirundo), and the ubiquitous Caspian Gull (Larus cachinnans).

Several potential predators are known, being almost exclusively avian raptors. These include white-throated hawks (Buteo albigula), variable hawks (B. polyosoma), bicolored hawks (Accipiter bicolor), and southern crested caracaras (Caracara plancus) (the latter most likely a predator only of young). When they encounter these potential predators while not nesting, Magellanic woodpeckers usually respond by being quiet and staying still.

Buzzards spend much of their day perched. The common buzzard is a typical Buteo in much of its behaviour. It is most often seen either soaring at varying heights or perched prominently on tree tops, bare branches, telegraph poles, fence posts, rocks or ledges, or alternately well inside tree canopies. Buzzards will also stand and forage on the ground.

The forest buzzard is very similar to the abundant summer migrant steppe buzzard Buteo buteo vulpinus, the head, the back and upperwings are brown, marked out with rufous edges to the feathers the amount of which varies between individuals. The chin is whitish and unmarked, the breast and belly are whitish but marked with a variable amount of brown spots, and the undertail coverts are plain whitish. There is variation and some adults show brown barring along the breast sides and the belly while all but the palest birds show a distinctive white ‘U’ mark in the middle of the otherwise blotched abdomen. The underwings are white, with a reddish-brown tinge on the lesser underwing coverts and a dark comma shaped mark at the tip of primary coverts .

Most of the slope is covered by vegetation which is not native to the location – black pine (Pinus nigra), European larch (Larix decidua), black locust (Robinia pseudoaccacia) and Norway spruce (Picea abies). The original community of oak-hornbeam forests (Sessile oak (Quercus petraea), common hornbeam (Carpinus betulus), field maple (Acer campestre)) can only be found in the upper parts of the profile. The formerly woodless areas tend to be covered by bushes of dog-rose (Rosa canina), blackthorn (Prunus spinosa) and common dogwood (Cornus sanguinea), atop the hill we may find an area of xerothermic grasslands such as spotted knapweed (Centaurea stoebe) and hairy oxytropis (Oxytropis pilosa). Klonk is the nesting place for a number of birds, among others the grey wagtail (Motacilla cinerea), Eurasian sparrowhawk (Accipited nisus) or the common buzzard (Buteo buteo).

These include Madeiran holly (Ilex perado), Azorean holly (Ilex azorica), flowering laurel (Viburnum tinus and Viburnum subcordatum), Azores juniper (Juniperus brevifolia), Azores laurel (Laurus azorica), Portugal laurel (Prunus lusitanica), Azorean laurel (Prunus azorica), woolly tree fern (Culcita macrocarpa), Azores blueberry (Vaccinium cylindraceum) and a wood rush (Luzula purpureo-splendens). Fauna is these forests and shrublands include rare terrestrial birds, such as the Azores bullfinch (Pyrrhula murina), endemic to the Azores, whose refuge is confined primarily to the existent Laurissilva forests of Pico da Vara. This rare bird is considered at risk for extinction. In addition to the bullfinch the zone is habitat for Common chaffinch (Fringilla coelebs moreletti), Common buzzard (Buteo buteo rothschild), Azores wood pigeon (Columba palumbuz azorica) and the São Miguel goldcrest (Regulus regulus azoricus), among others.

John James Audubon illustrated the Harris's hawk in The Birds of America (published, London 1827–38) as Plate 392 with the title "Louisiana Hawk -Buteo harrisi". The image was engraved and colored by the Robert Havell, London workshops in 1837. The original watercolor by Audubon was purchased by the New York History Society where it remains to this day (January 2009).

The existence of these extinct giants suggests that predator-prey interactions involving lemurs were more complex than they are today. Today, predator size restricts owls to the smaller lemurs, usually 100 g (3.5 oz) or less, while the larger lemurs fall victim to the larger diurnal birds of prey, such as the Madagascan harrier-hawk (Polyboroides radiatus) and the Madagascar buzzard (Buteo brachypterus).

The parents defend their nesting grounds against other birds of prey, such as the red-backed hawk (Buteo polyosoma), and the golden eagle (Aquila chrysaetos); during approaches by such potentially dangerous species, the nestlings will tuck away their heads. It seems that 2 or 3 young are raised on a regular basis, unlike in many other Accipitridae where only the strongest nestling survives.

He was kept birds in cages and looked after other animals from a young age. As a youth Newton shot game birds – black or red grouse, common pheasant, partridge. Birds became an abiding interest. Those included the great bustard (Otis tarda), Montagu's harrier (Circus pygargus), ravens, buzzards (Buteo sp.), redpolls, wrynecks (Jynx), which are small woodpeckers that specialise in feeding on ants.

This fairly large raptorial species is with wingspan ranging from . Individuals can weigh from with females typically being larger and heavier than males. Weights appear to increase from summer to winter in adults, going from an average of in males and from in females. Among the members of the genus Buteo, it is sixth heaviest, the fifth longest, and the fourth longest winged.

The zone-tailed hawk (Buteo albonotatus), which resembles the turkey vulture (Cathartes aura), may provide one such example. It flies amongst them, suddenly breaking from the formation and ambushing its prey. Here the hawk's presence is of no evident significance to the vultures, affecting them neither negatively or positively. There is some controversy over whether this is a true case of mimicry.

The Alaska red-tailed hawk (Buteo jamaicensis alascensis) is a subspecies of red-tailed hawk that breeds (and is probably resident) from southeastern coastal Alaska to the Queen Charlotte Islands and Vancouver Island in British Columbia. Despite its northerly distribution, this is the second smallest of the red-tailed hawks. Only the Jamaican red-tailed hawk (B. j. jamaicensis) is smaller.

The Socorro red-tailed hawk (Buteo jamaicensis socorroensis) is a subspecies of red-tailed hawk endemic to Socorro Island, off the west coast of Mexico. The wing chord of males can range from , averaging , and, in females, it ranges from , averaging . Males and females average in tail length, in tarsal length and in culmen length. One female was found to have weighed .

In the park there are 19 species of birds, of which eight are endemic. Many of these are endangered, including Ardea purpurea bournei (Bourne's heron), Acrocephalus brevipennis (Cape Verde warbler) and Cape Verde buzzard (Buteo bannermani). Four species of mammals are found, including one species of monkey. Six species of reptiles are found (four are endemic) and one endemic amphibian species.

Although they overlap in range with most other American diurnal raptors, identifying most mature red-tailed hawks to species is relatively straightforward, particularly if viewing a typical adult at a reasonable distance. The red-tailed hawk is the only North American hawk with a rufous tail and a blackish patagium marking on the leading edge of its wing (which is obscured only on dark morph adults and Harlan’s hawks by similarly dark colored feathers). Other larger adult Buteo in North America usually have obvious distinct markings that are absent in red-tails, whether the rufous- brown "beard" of Swainson's hawks (Buteo swainsonii) or the colorful rufous belly and shoulder markings and striking black-and-white mantle of red- shouldered hawks (also the small "windows" seen at the end of their primaries).Robbins, C. S., Bruun, B., & Zim, H. S. (2001).

Up to tens of thousands of these Buteos can be seen each day during the peak of their migration. Any of the prior mentioned common Buteo species may have total populations that exceed a million individuals. On the other hand, the Socotra buzzard and Galapagos hawks are considered vulnerable to extinction per the IUCN. The Ridgway's hawk is even more direly threatened and is considered Critically Endangered.

The species is slightly smaller than the largest members of widespread raptor genera such as the largest Buteo and Falco species but is usually larger than other forest raptors in its range apart from vultures and other eagle species. The total length of full grown ornate hawk-eagle is .Howell, S. N., & Webb, S. (1995). A guide to the birds of Mexico and northern Central America.

Distant juvenile Bonelli's could conceivably be mistaken for the long-legged buzzard (Buteo rufinus), but the buzzard is also smaller and is shorter tailed with prominent dark carpal patches and dark trailing wing edges. Furthermore, the buzzard usually holds its wings in a noticeable dihedral when flying in a soar.Forsman, D. (2016). Flight Identification of Raptors of Europe, North Africa and the Middle East.

The black-chested buzzard-eagle (Geranoaetus melanoleucus) is a bird of prey of the hawk and eagle family (Accipitridae). It lives in open regions of South America. This species is also known as the black buzzard-eagle, grey buzzard- eagle or analogously with "eagle" or "eagle-buzzard" replacing "buzzard- eagle", or as the Chilean blue eagle. It is sometimes placed in the genus Buteo.

Report No. 17, the Accipiters. USDI-BLM Tech. Note 335. Despite its gracile appearance, the Cooper's hawk, like the northern goshawk, is extremely powerful for its size and presumably able to capture larger prey relative to its size than other raptors such as falcons and Buteos (including red-tailed hawks (Buteo jamaicensis)) due to its unusually high-speed foot velocity and resulting impact during prey captures.

The eyes of adult roadside hawks are whitish or yellow. As suggested by its specific name (magni = large; rostri = beak), its beak is relatively large. The roadside hawk may be marginally the smallest hawk in the widespread genus Buteo, although Ridgway's hawk and the white-rumped hawk are scarcely larger. In flight, the relatively long tail and disproportionately short wings of the roadside hawk are distinctive.

Pliny, x. 8. § 10. Crawford suggests that the buteo of the legend was not a hawk, but a flamingo, based on the appearance of a bird resembling a flamingo on the coins of Gaius Fabius Hadrianus, who may have sought to associate himself with that family by the use of such a symbol. Hadrianus and his descendants form the last distinguishable family of the Fabii.

The only other widely found European Buteo, the rough-legged buzzard, comes to winter extensively with common buzzards. It was found in southern Sweden, habitat, hunting and prey selection often overlapped considerably. Rough-legged buzzards appear to prefer slightly more open habitat and took slightly fewer wood mice than common buzzard. Roughlegs also hover much more frequently and are more given to hunting in high winds.

Birds of North America: a guide to field identification. Macmillan. In perched individuals, even as silhouettes, the shape of large Buteos may be distinctive, such as the wingtips overhanging the tail in several other species, but not in red-tails. North American Buteos range from the dainty, compact builds of much smaller Buteos, such as broad-winged hawk (Buteo platypterus) to the heavyset, neckless look of ferruginous hawks or the rough-legged buzzard which has a compact, smaller appearance than a red-tail in perched birds due to its small bill, short neck and much shorter tarsus, while the opposite effect occurs in flying rough-legs with their much bigger wing area. In flight, most other large North American Buteo are distinctly longer and slenderer winged than red-tailed hawks, with the much paler ferruginous hawk having peculiarly slender wings in relation to its massive, chunky body.

Although the species has been observed for more than 110 years, it wasn't recognized as an official species until 2010. Prior to that, it was assumed to be the same species as B. buteo. There has been much debate about the taxonomic position of the Socotra buzzard. It is genetically closest to the taxa rufinus and bannermani, but its plumage is most similar to the taxa trizonatus/oreophilus.

Hence, in this case the scientific name Buteo melanoleucus can apply, even though the black- and-white hawk-eagle was earlier described under exactly that name, while the senior homonym melanoleucus still applies to the latter species when placed in Spizaetus according to the usual ICZN rules. Consequently, the proper name to use for each bird has through a number of coincidences become the one the other species was described under.

The laughing falcon breeds in rock crevices, tree cavities, or occasionally in abandoned nests of a Buteo hawk or caracara; in general however it does not even gather nesting material in significant quantities. It lays one or two eggs according to some sources, but according to othersE.g. Stiles & Skutch (1989) always just one. The eggs have heavy dark brown markings on a brown or whitish or pale buff background.

The similarity in plumage between juvenile European honey buzzard and common buzzard may have arisen as a partial protection against predation by northern goshawks. Although that formidable predator is capable of killing both species, it is likely to be more cautious about attacking the better protected Buteo species, with its stronger bill and talons. Similar Batesian mimicry is shown by the Asian Pernis species, which resemble the Spizaetus hawk-eagles.

Wildlife includes several species of interest. There are six animal species on the reserve that benefit from protection status: wolverine (Gulo gulo), boreal woodland caribou (Rangifer tarandus caribou), golden eagle (Aquila chrysaetos), bald eagle (Haliaeetus leucocephalus), rock vole (Microtus chrotorrhinus) and least weasel (Mustela nivalis). Three other species are also considered of "heritage interest", the willow ptarmigan (Lagopus lagopus), osprey (Pandion haliaetus) and rough-legged buzzard (Buteo lagopus).

The Jamaican red-tailed hawk (Buteo jamaicensis jamaicensis) is the nominate subspecies of the red-tailed hawk, a bird of prey of North America. The subspecies B. j. jamaicensis occurs in the northern West Indies, including Jamaica, Hispaniola, Puerto Rico and the Lesser Antilles but not the Bahamas or Cuba. El Yunque National Forest, Puerto Rico, holds some of the highest known density of Jamaican red-tailed hawks.

This species is quite short-winged, and has a fast agile flight for a Buteo. Juvenile Cristalino River, South Amazon, Brazil It feeds mainly on lizards and snakes, but will also take small mammals, birds and frogs. It usually sits on an open high perch from which it swoops on its prey, but will also hunt from a low glide. The nest is of sticks and built high in a tree.

Golden eagles (Aquila chrysaetos) are the only avian predators large enough to regularly take full-grown white-tailed jackrabbits, though ferruginous hawks (Buteo regalis) and great horned owls (Bubo virginianus) may occasionally take an adult, though these latter two species and other largish raptorial birds typically attack young.Olendorff, Richard R. (1976). The Food Habits of North American Golden Eagles. American Midland Naturalist (The University of Notre Dame) 95 (1): 231–236.
|
|
They have also been recorded opportunistically pirating birds from peregrine falcons (Falco peregrinus), prairie dogs from ferruginous hawks (Buteo regalis) and even jackrabbits from golden eagles. When they approach scavengers like dogs, gulls or vultures at carrion sites, they often aggressively attack them and try to force them to disgorge their food. Healthy adult bald eagles are not preyed on in the wild and are thus considered apex predators.

The talons and feet of red-tailed hawks are relatively large for a Buteo hawk, in an average sized adult red-tail the "hallux-claw" or rear talon, the largest claw on all accipitrids, averages about . In fact, the talons of red-tails in some areas averaged of similar size to those of ferruginous hawks which can be considerably heavier and notably larger than those of the only slightly lighter Swainson's hawk. This species may exert an average of about of pressure per square inch (PSI) through its feet. Owing to its morphology, red-tailed hawks generally can attack larger prey than other Buteo hawks typically can and are capable of selecting the largest prey of up to their own size available at the time that they are hunting, though in all likelihood numerically most prey probably weighs about 20% of the hawk's own weight (as is typical of many birds of prey).

Many valuable wild animals and medicinal plants are found in the forested mountain areas. The Manchurian hare, valued for its fur, and some species of rodent such as the rat hamster and the eastern field vole are believed to be peculiar to the North-east forest. Among birds, finches, buteo hawks, needle-footed owls, black and white barriers, and certain species of flycatcher are typical. Among semi aquatic animals, the lung-less newts are notable.

Wintering migrants from southern Ontario may range east to southern Maine and south to as far as the Gulf Coast and Florida. The western limits of this race's range are slightly ambiguous and they may hybridize extensively with the western red-tailed hawk (Buteo jamaicensis calurus) in timbered stretches of the Great Plains. The breeding range of B. j. borealis seems to include most of Texas (perhaps excluding the western sections), Oklahoma, Kansas and Nebraska.

85 species of birds have been observed with breeding activity of 32-64 probable. 12 species of raptors were observed. Nesting of 7 was confirmed including American kestrel (Falco sparverius), barn owl (Tyto alba), screech owl (Otus asio), red-shouldered hawk (Buteo lineatus). The turkey vulture (Cathartes aura) and the prairie falcon (Falco mexicanus) breed on adjacent slopes. Cooper’s hawk (Accipiter cooperi) and northern harrier (Circus cyanus) may nest in Oak Park.

Population density ranges from 100 individuals per in dry forests to 250–600 individuals per km2 in gallery and secondary forests. The ring-tailed lemur has both native and introduced predators. Native predators include the fossa (Cryptoprocta ferox), the Madagascar harrier-hawk (Polyboroides radiatus), the Madagascar buzzard (Buteo brachypterus) and the Madagascar ground boa (Acrantophis madagascariensis). Introduced predators include the small Indian civet (Viverricula indica), the domestic cat and the domestic dog.

When his troops had repulsed the offensive and retired, assuming the Carthaginians would now rest, he was surprised by a second attack from the bulk of the Carthaginian force that Hannibal had kept in reserve. The Roman entrenchments were captured.Zonaras. 9.3. His dictatorship is also notable for the concurrent appointment of Marcus Fabius Buteo. It marked the only occasion in Roman history where two dictators were in office at the same time.

The red-tailed hawk was formally described in 1788 by the German naturalist Johann Friedrich Gmelin under the binomial name Falco jamaicensis. Gmelin based his description on the "cream-coloured buzzard" described in 1781 by John Latham in his A General Synopsis of Birds. The type locality is Jamaica. The red-tailed hawk is now placed in the genus Buteo was erected by the French naturalist Bernard Germain de Lacépède in 1799.

Characteristic fauna species include Ciconia nigra (Black stork), Buteo rufinus (Long-legged buzzard) and Felis lynx (Eurasian lynx). However, numerous endangered or threatened animal species within the biosphere reserve struggle for survival, including Falco subbuteo (Eurasian hobby) and Gazella subgutturosa (Black-tailed gazelle) among others. The region is also home to species of commercial or traditional importance, such as Cistanche salsa, which grows in desert habitats and is used for traditional Chinese medicine.

Proportionately, goshawks have longer, broader wings, shorter tail and a generally more Buteo-like form overall. Adult goshawks also have broad supercilia, pale gray color on the underside and a much darker coloring on the back. Given reasonable views, adult goshawks are very different looking and hard to mistake for any Cooper's hawk. Meanwhile, the juvenile goshawk is much paler edged above than the smaller Cooper's, including a panel formed along larger wing coverts.

Despite its English name, this species is more closely related to kites of the genera Leptodon and Chondrohierax than to true buzzards in Buteo. The binomen is due to Linné. It is derived from Ancient Greek pernes περνης, a term used by Aristotle for a bird of prey, and Latin apivorus "bee-eating", from apis, "bee" and -vorus, "-eating". In fact, bees are much less important than wasps in the birds' diet.

The most common mammalian predators are mountain lions (Felis concolor) and coyotes (Canis latrans). Other common mammals are Black- tailed jackrabbit (Lepus californicus), desert cottontail, (Sylvilagus auduboni) and kangaroo rats (Dipodomys merriami and Dipodomys spectabilis). Common birds of prey include golden eagles (Aquila chrysaetos), Swainson's hawk (Buteo swainsoni), Northern harrier (Circus cyaneus), and burrowing owl (Athene cunicularia). Other birds include roadrunner (Geococcyx californianus), quail (Callipepla gambelii and Callipepla squamata), doves (Zenaida macroura and Zenaida asiatica).

The record contribution for insects surely for Europe was study in central Poland where a single beetle, the common cockchafer (Melolontha melolontha), was found to constitute 25% of the prey items.Ciach, M. (2006). Common Cockchafer (Melolontha melolontha; Coleoptera: Scarabaeidae) in the diet of long-eared owl Asio otus. Buteo, 15, 23-25. Based on a couple studies in Algeria, insects are a common supplemental food there, contributing up to about 17.3% of the prey items.

Body mass can show considerable variation. Buzzards from Great Britain alone can vary from in males, while females there can range from . A pale individual in Europe In Europe, most typical buzzards are dark brown above and on the upperside of the head and mantle, but can become paler and warmer brown with worn plumage. The flight feathers on perched European buzzards are always brown in the nominate subspecies (B. b. buteo).

The Pare people live in the area. The Pare Mountains are accessible by 4WD, but there are few roads in the South Pares. Species in the Pare mountains include the endemic South Pare white-eye (Zosterops winifredae), mountain buzzard (Buteo oreophilus), olive woodpecker (Mesopicos griseocephalus), moustached tinkerbird (Pogoniulus leucomystax) and the African hill babbler (Pseudoalcippe abyssinica). During its German occupation, the area around Neu-Hornow (modern Shume) was used for lumber exports along the Usambara Railway.

American crows (Corvus brachyrhynchos) mobbing a red-tailed hawk (Buteo jamaicensis). Mobbing in animals is an antipredator adaptation in which individuals of prey species mob a predator by cooperatively attacking or harassing it, usually to protect their offspring. A simple definition of mobbing is an assemblage of individuals around a potentially dangerous predator. This is most frequently seen in birds, though it is also known to occur in many other animals such as the meerkat and some bovines.

Aetobarbakinoides was first named by Julia B. Desojo, Martin D. Ezcurra and Edio E. Kischlat in 2012 and the type species is Aetobarbakinoides brasiliensis. The generic name is derived from Greek aetobarbakina meaning "long-legged buzzard" (the common name of Buteo rufinus) and from Latin oides meaning "form". It refers to its elongated humerus and tibia and the close relation to the "eagle reptile", Aetosaurus. The specific name refers to Brazil, the country in which the holotype was found.

In Arizona, potential scaled quail predators include mammals, birds, and reptiles. Most scaled quail kills are made by avian predators including northern harrier (Circus cyaneus), red-tailed hawk (Buteo jamaicensis), American kestrel (Falco sparverius), prairie falcon (Falco mexicanus), and great horned owl (Bubo virginianus). In New Mexico, predators on scaled quail include hawks, owls, coyote (Canis latrans), and snakes. In Colorado, potential predators of scaled quail include coyote, gray fox (Urocyon cinereoargenteus), red fox (Vulpes vulpes), kit fox (V.

Its feet are feathered to the toes as an adaptation to its Arctic home range. Its scientific name reflects this feature; the genus name Buteo is the Latin name of the common buzzard, and lagopus, is derived from Ancient Greek lago (λαγως), meaning "hare", and pous (πους), "foot". Its talons are relatively small, reflecting their preferred choice of prey. Distinguishing characteristics in all plumages include long white tail feathers with one or more dark subterminal bands.

Red-tailed hawks are also vulnerable to fatal bacterial infections include peritonitis, myocarditis, granulamotous, sarcocystosis and mycobateriosis as well as some forms of viral infection, to which immature hawks especially, as they often have less access to coverage in poor weather conditions, are most vulnerable. Neither this nor other Buteo hawks were found to be highly susceptible to long-term DDT egg-shell thinning due to being part, generally, of relatively short, terrestrial-based food chains.

Olson, S. L. (2006). Reflections on the systematics of Accipiter and the genus for Falco superciliosus Linnaeus. Bulletin of the British Ornithologists' Club 126:69–70. Genetic studies of three Asian Accipiter species showed that they may not be a monophyletic group, with various clades divisions outside traditional subfamily lines, with even the sharp-shinned hawk-like and aptly named tiny hawk (Accipiter supercilious) appearing to cluster outside of the genus nearer very dissimilar genera like Buteo and Milvus.

The genus Leucopternis currently is considered to contain 10 species of forest-dwelling hawks ranging from Argentina and Uruguay to Southern Mexico. L. kuhli is considered the sister species of L. melanops. Both hawks also happen to be the smallest members of their genus since their total length is < 40 cm. Analysis of mtDNA phylogenetic trees showed that there were three highly supported clades giving a polyphyletic relationship between the species of the genera Leucopternis, Buteogallus and Buteo.

Barred hawks have a snout- like bill that makes them look like they have a heavy head. Despite being a fairly large hawk, of similar size to a large member of the Buteo genus, its wing spread is relatively smaller than most related largish hawks, which allow them to maneuver through the thick forest canopy easier. Total length is from and wingspan is from . M. princeps weighs about Chavarría-Duriaux, L., Hille, D. C., & Dean, R. (2018).

The Tres Marias red-tailed hawk (Buteo jamaicensis fumosus) is a relatively small subspecies of red-tailed hawk endemic to Islas Marías, an island some off the coast of Mexico. Unlike some other island races, the validity of this race has rarely been called into question. The wing chord of males can range from , averaging , and, in females, it ranges from , averaging . Males and females average in tail length, in tarsal length and in culmen length.

Before the Hawaiian crow became extinct in the wild, the species was found only in the western and southeastern parts of Hawaii. It inhabited dry and mesic forests on the slopes of Mauna Loa and Hualālai at elevations of 3,000 to 6,000 feet. Ōhia lehua (Metrosideros polymorpha) and koa (Acacia koa) were important tree species in its wild habitat. Extensive understory cover was necessary to protect the ʻalalā from predation by the Hawaiian Hawk, or io (Buteo solitarius).

The Buteo hawks include many of the most widely distributed, most common, and best-known raptors in the world. Examples include the red-tailed hawk of North America, the common buzzard of Eurasia, and the roadside hawk of tropical Central and South America. Most Northern Hemisphere species are at least partially migratory. In North America, species such as broad-winged hawks and Swainson's hawks are known for their huge numbers (often called "kettles") while passing over major migratory flyways in the fall.

The southwestern red-tailed hawk (Buteo jamaicensis fuertesi) Website based on / supplement to book, is a subspecies of red-tailed hawk that breeds from northern Chihuahua to southern Texas. It winters in Arizona, New Mexico and southern Louisiana. This seems to be a particularly large subspecies, although its size is not drastically different from the western red-tailed hawk (B. j. calurus), and, going on average wing size and tarsal length, this appears to be the largest race of red-tailed hawk.

The cycle of meadow vole abundance is an important proximate factor affecting the life histories of its major predators. Meadow voles are usually the most abundant small mammals in northern prairie wetlands, often exceeding 40% of all individual small mammals present. Numbers of short-eared owls, northern harriers, rough-legged hawks (Buteo lagopus), coyotes (Canis latrans), and red foxes were related to large numbers of meadow voles in a field in Wisconsin. Predator numbers are positively associated with meadow vole abundance.

The other is the rough- legged buzzard (Buteo lagopus). The pale morph of the closely related but more slender rough-legged species is best distinguished by its darker coloration, with a broad black tail band and a dark band across the chest. The dark morph Rough-leg is more a slaty coloration than the more brownish dark morph ferruginous. Swainson's hawks and especially rough-legged buzzards can be nearly as long-winged but are less bulky and heavily built than the ferruginous.
|
|
Active flight is slow and deliberate, with deep wing beats. Wing beats are somewhat less rapid in active flight than in most other Buteo hawks, even heavier species such as ferruginous hawks tend to flap more swiftly, due to the morphology of the wings. In wind, it occasionally hovers on beating wings and remains stationary above the ground, but this flight method is rarely employed by this species. When soaring or flapping its wings, it typically travels from , but when diving may exceed .

Northwest science, 91(1), 15-26. Occasionally, Cooper's hawks are known to hunt bats. They are said to usually capture bats on the wing rather than search them out. Findings were that in Carlsbad Caverns that Cooper's (and also sharp-shinned) hawks were the were the most efficient avian predators of bats near the cave entrance (rating as more successful than most Buteo hawks and particularly more so than larger and less agile raptors like red-tailed hawks and large owls).

As red-tailed hawks in conflict with other more closely related Buteo hawks rarely (if ever) result in mortality on either side, goshawks and red-tailed hawks do seem to readily kill one another. Adults of both species have been shown to be able to kill adults of the other. A red-tailed hawk is mobbed by a northern mockingbird in the urban environment of Philadelphia, Pennsylvania. The great horned owl occupies a similar ecological niche nocturnally to the red-tailed hawk.

Below the escarpment are seasonally flooded forests dominated by silver maple, and green ash with swamp white oak, American bladdernut, and great water-leaf. The site contains many rare plants including dwarf lake iris (Iris lacustris). Other noteworthy species within the SNA are variegated horsetail (Equisetum variegatum), Hooker's orchid (Platanthera hookeri), long-spurred violet (Viola rostrata), and large-flowered ground-cherry (Leucophysalis grandiflora). Rare animals include red-shouldered hawk (Buteo lineatus), Midwest Pleistocene vertigo (Vertigo hubrichti), Iowa Pleistocene vertigo (V.

Ice Mountain provides habitats for breeding neotropical birds including warblers, vireos, and thrushes as well as various types of birds common in the central Appalachian Mountains. Ice Mountain also serves as a habitat for bald eagles and ravens, which nest in the mountain's Raven Rocks outcrop named for them. Other bird species include American goldfinch (Carduelis tristis), great crested flycatcher (Myiarchus crinitus), indigo bunting (Passerina cyanea), red-tailed hawk (Buteo jamaicensis), and American black (Coragyps atratus) and turkey (Cathartes aura) vultures.

These are often supported by an exceptionally diverse, dense population of rodents there. The Bale Mountains golden eagles were recorded kleptoparatisizing steppe eagles, augur buzzard (Buteo augur), pallid harrier (Circus macrourus) and lanner falcons (Falco biarmicus) and the eagles were themselves kleptoparatisized by steppe eagles on three occasions. The golden eagles were also observed to chase tawny and steppe eagles out of their nesting territories. In the Bale Mountains, the golden eagle overlaps with perhaps its closest living relative, the Verreaux's eagle.

He and his cronies begin to bully and persuade the townspeople into allowing him to take over the town. Oblivion's mortician, Gaunt, who possesses supernatural ability to foresee death, seeks out the Marshal's son, Zack (Richard Joseph Paul), who is prospecting in the wilderness. Meanwhile, Zack saves a "native", Buteo (Jimmie F. Skaggs), from an untimely death by giant scorpion. They team up just before Gaunt arrives with the news of Marshal Stone's death, and they all journey together to Oblivion for the funeral.

Sulla died in 78 BC, and in 70 BC, the Consuls Pompey Magnus and Marcus Licinius Crassus repealed Sulla's constitutional reforms, including his restoration of the Servian organization to this assembly. They restored the less aristocratic organization (from 241 BC by the Censors Marcus Fabius Buteo and Gaius Aurelius Cotta). The organization of the Centuriate Assembly was not changed again until its powers were all transferred to the Roman Senate by the first Roman Emperor, Augustus, after the fall of the Roman Republic in 27 BC.

Agkistrodon piscivorus is preyed upon by snapping turtles (Chelydra serpentina), falcons, American alligators (Alligator mississippiensis), horned owls (Bubo virginianus), eagles, red-shouldered hawks (Buteo lineatus), loggerhead shrikes (Lanius ludovicianus), and large wading birds, such as herons, cranes, and egrets. It is also preyed upon by ophiophagous snakes, including their own species. Humphreys (1881) described how a specimen was killed and eaten by a captive kingsnake. On the other hand, Neill (1947) reported captive kingsnakes (Lampropeltis getula) were loath to attack them, being successfully repelled with "body blows".

Atticus' first mention in history is his election as censor in 247, alongside Aulus Atilius Caiatinus, a plebeian with a distinguished career (twice consul in 258 and 254, dictator in 249). During the third century, the Manlii and the Atilii were the allies of the great patrician gens Fabia and members of these three gentes are often found together in the Fasti. Moreover, one of the consuls of 247 was Numerius Fabius Buteo. Friedrich Münzer furthermore suggested that Atticus was married to a Fabia.

This anomaly led modern historians to suppose that Flamininus was backed by several powerful politicians. Early prosopographers such as Friedrich Münzer and H. H. Scullard thought that he was a member of the political faction led by the Fabii. However this view has been contested, because the Fabii were in decline after the death of Buteo and the Cunctator. Flamininus was elected consul, together with the plebeian Sextus Aelius Paetus Catus, as the consul posterior, which means the Centuriate Assembly elected him in second place, after Aelius.

The similarity in plumage between juvenile crested honey buzzards and the Spizaetus hawk-eagles may have arisen as a partial protection against predation by larger raptors. The eagles have stronger bills and talons, and are likely to be less vulnerable than the Pernis species. Similar mimicry is shown by the juveniles of the European honey buzzard, which resembles the common buzzard. Although the northern goshawk is capable of killing both species, it is likely to be more cautious about attacking the better protected Buteo species.

As its preferred habitat seldom overlaps with larger eagles such as golden eagles and white-tailed eagles, the eastern imperial eagle is usually the top avian predator in its breeding grounds. In particular, smaller raptors with largely overlapping diets (i.e. ground squirrels, hamsters, voles & lagomorphs) and habitat preferences such as saker falcons (Falco cherrug) and long-legged buzzards (Buteo rufinus) are often at a disadvantage in direct competition with the eagle species.Bagyura, J., Szitta, T., Haraszthy, L., Viszló, L., Fidlóczky, J., & Prommer, M. (2012).

The white-eyed buzzard (Butastur teesa) is a medium-sized hawk, distinct from the true buzzards in the genus Buteo, found in South Asia. Adults have a rufous tail, a distinctive white iris, and a white throat bearing a dark mesial stripe bordered. The head is brown and the median coverts of the upper wing are pale. They lack the typical carpal patches on the underside of the wings seen in true buzzards, but the entire wing lining appears dark in contrast to the flight feathers.

Hamilcar, upon taking command in the summer of 247 BC,Polybius 1.56.2 punished the rebellious mercenaries (who had revolted because of overdue payments) by murdering some of them at night and drowning the rest at sea,Zonaras 8.16 and dismissing many to different part of northern Africa. With a reduced army and fleet, Hamilcar commenced his operations.Lazenby, John .F, ‘’First Punic War’’, pp145 Romans had divided their forces, Consul L. Caelius Metellus was near Lilybaeum, while Numerius Fabius Buteo was besieging Drepanum at that time.

Birds of prey of southern Africa: Their identification and life histories. Croom Helm, Beckenham (UK). 1983. The main call of the Bonelli's eagle is done during the courtship display and, sometimes, also at the nest. Its main call consists of a loud, shrill, somewhat far-carrying scream, yuiii-yuiii-gii-gii or a drawn- oout heeeeii-heeeeii with slight regional or even individual variations. Its call is farther carrying than the “puppy-like” one of the golden eagle and is reminiscent in pitch of that of the red-tailed hawk (Buteo jamaicensis).

Parts of the reserve show the effect of agriculture on the native ecosystem, as much of the land in the upper part of the reserve is abandoned farmland. Bird species native to the acacia koa–ōhia forest include the Hawaiian crow (Corvus hawaiiensis), the akepa (Loxops coccineus), Hawaii creeper (Oreomystis mana), ʻakiapōlāʻau (Hemignathus munroi), and Hawaiian hawk (Buteo solitarius), all of which are endangered, threatened, or near threatened; the Hawaiian crow in particular is extinct in the wild, but there are plans to reintroduce the species into the Hakalau reserve.

Common birds include golden eagles (Aquila chrysaetos), Swainson's hawk (Buteo swainsoni), northern harrier (Circus cyaneus), burrowing owl (Athene cunicularia), greater roadrunner (Geococcyx californianus), quail (Callipepla gambelii and Callipepla squamata), horned lark (Eremophila alpestris), western meadowlark (Sturnella neglecta), doves (Zenaida macroura and Zenaida asiatica), and black-throated sparrow (Amphispiza bilineata). Common reptiles include collared lizards (Crotaphytus collaris), roundtail horned lizard (Phrynosoma modestum), striped whipsnake (Masticophis taeniatus), and western diamondback rattlesnake (Crotalus atrox). Common amphibians include New Mexico spadefoot toad (Spea multiplicata), Great Plains toad (Bufo cognatus), green toad (Bufo debilis), and red-spotted toad (Bufo punctatus).

High densities of the Tawny Owl (Strix aluco) in mature deciduous forests of Latium (central Italy). Buteo, 12: 111-118. Territory size varied in the area of Rome by habitat, with wooded city parks, with 3.3 territories per square kilometer, and well-wooded suburbs, with 5.7 territories per square kilometer, holding peak numbers among the habitat types and having an average territory size of , while developed areas of the city, rural areas and farmland (where average territory was ) all held considerably lower densities of territories.Ranazzi, L., Manganaro, A., Ranazzi, R., & Salvati, L.

Native mammals include white-tailed deer (Odocoileus virginianus), coyote (Canis latrans), collared peccary (Pecari tajacu), nine-banded armadillo (Dasypus novemcinctus), Virginia opossum (Didelphis virginiana), southern spotted skunk (Spilogale angustifrons), Mexican cottontail (Sylvilagus cunicularius), desert cottontail (Sylvilagus audubonii), and rock squirrel (Otospermophilus variegatus). Native birds include great-tailed grackle (Quiscalus mexicanus), mourning dove (Zenaida macroura), Stygian owl (Asio stygius), red-tailed hawk (Buteo jamaicensis), northern harrier (Circus cyaneus), prairie falcon (Falco mexicanus), Harris's hawk (Parabuteo unicinctus), barn owl (Tyto alba), hooded oriole (Icterus cucullatus), and common raven (Corvus corax).

Various birds and mammals, such as the fisher (Martes pennanti), are among the predators of eggs and young spotted owls. Northern goshawks (Accipiter gentilis) and crows may prey on juvenile spotted owls, while great horned owls (Bubo virginianus), red-tailed hawks (Buteo jamaicensis), and golden eagles (Aquila chrysaetos) are likely predators of both juveniles and adults. Great horned owls and barred owls may compete with spotted owls for food and space in some areas. Barred owls may have a negative effect on northern spotted owl survival and fecundity in some areas.

Title page of Logistica (1559) Buteo was born in Dauphine or possibly Charpey and belonged to the order of St. Anthony. He studied under Oronce Fine and wrote on geometry and exposed Fine publishing a few books Opera Geometrica (1554), Logistica (1559), De quadratura circuli libri duo (1559). He died in a cloister about 1560-64 but some sources suggest he died in Canar in 1572. His contributions included a systematic way of eliminating unknowns in systems of linear equations which he demonstrated in Logistica with three equations and three unknowns.

While wintering, rough- legged buzzards or hawks may be vulnerable to predation by night to Eurasian eagle-owls (Bubo bubo) or great horned owls (Bubo virginianus) and rarely, during day, other large Buteo hawks, including those of their own species. Besides predation, it could be other reasons for nestling mortality among rough-legged buzzards. Nestlings in their first two weeks have a lousy temperature regulation. In the tundra landscape, they nest on the ground and during hot weather, they could go out of the nest seeking shelter from the sun.

The Cape Verde Islands are home to five endemic bird species. The Iago sparrow (Passer iagoensis) and Cape Verde swift (Apus alexandri) are found on most of the islands. The endangered Raso lark (Alauda razae) is limited to uninhabited Raso Island, and the Cape Verde warbler (Acrocephalus brevipennis) is found only on Santiago Island. The Cape Verde buzzard (Buteo bannermanni) is also endemic to the islands. Bourne's heron or Cape Verde heron (Ardea purpurea bournei) is a endangered subspecies of heron endemic to the islands, with 40 birds living on Santiago Island.

Hawks, like most birds, are tetrachromats having four types of colour receptors in the eye. These give hawks the ability to perceive not only the visible range but also ultraviolet light. Other adaptations allow for the detection of polarised light or magnetic fields. This is due to the large number of photoreceptors in the retina (up to 1,000,000 per square mm in Buteo, compared to 200,000 in humans), a high number of nerves connecting these receptors to the brain, and an indented fovea, which magnifies the central portion of the visual field.
|
|
Alternately, old nests of other Buteo hawks, corvids, golden eagles and even leaf nests of tree squirrels have also been used by red-tailed hawks. Both members of the pair will build the nests but the female spends more time forming the bowl, with the greatest activity often in the morning and nest building completed in a week or less. The nest is generally in diameter, with a mean of roughly , and can be up to tall after several years use. The inner bowl averages about wide and deep.

This species is often placed in the monotypic genus Spizastur, but has recently been moved to Spizaetus e.g. by the American Ornithologists' Union, as it appears that the ornate hawk-eagle (S. ornatus) is its sister taxon. This has created quite some taxonomic confusion, which has largely gone unnoticed however: Originally, the name Spizaetus melanoleucus was given by Louis Jean Pierre Vieillot to the black-chested buzzard-eagle in 1819, while the black-and-white hawk-eagle had been described in 1816 by the very same scientist as Buteo melanoleucus.

It is a vector for Avipoxvirus, Newcastle disease virus, Falconid herpesvirus 1 (and possibly other Herpesviridae), and some mycoses and bacterial infections. Endoparasites include Plasmodium relictum (usually not causing malaria in the peregrine falcon), Strigeidae trematodes, Serratospiculum amaculata (nematode), and tapeworms. Known peregrine falcon ectoparasites are chewing lice, Ceratophyllus garei (a flea), and Hippoboscidae flies (Icosta nigra, Ornithoctona erythrocephala). In the Arctic Peregrine falcons chasing away small rodent predators from their nesting territory and Rough-legged Hawks (Buteo lagopus) could use these hot spots as a nesting territory.

Henderson and Robert Powell (2009) record that this species may be eaten by another anole, A. cuvieri, as well as the non-native mongoose, Herpestes javanicus and the bird Margarops fuscatus, a thrasher. In a 2008 study of the reptilian components of the diets of Caribbean birds, Powell and Henderson record the birds of prey Buteo jamaicensis and Falco sparverius feeding on this anole. Rios-Lopez et al. recorded in 2015 that the Puerto Rican endemic bird Todus mexicanus, a species of tody known locally as San Pedrito, eats this lizard.

Florida Nat, 17, 21-31. Often nests are lined by the Cooper's pair with bark or odd bits of greenery. The male grabs at bark like prey, while the female, if participating, may tear off bark with her bill; the piles of bark may be up to 3 inches deep by the time eggs are laid, though green spray is added considerably less often than other species of hawks such as Buteo. One male, unusually, was seen to be engaging in nest building while helping parent an active brood in mid-summer.

As easily one of the most abundant of all American raptorial birds, red-tailed hawks have been recorded as interacting with every other diurnal bird of prey. Due to the extreme dietary plasticity of red-tails, the food habits of other birds of prey regularly overlap considerably with red-tails. Furthermore, due to its ability to nest in varied habitats, home ranges also frequently abut those of other raptor species. The most obvious similar species in their range are other Buteo hawks, especially larger species with a similar ecological niche.
|
|
These practices have caused range expansions of many other species of birds but declines in many others. Of these three Buteo species, the Swainson's hawk is most dissimilar, being a long-distance migrant which travels to South America each winter and, for much of the year, prefers to prey on insects (except for during breeding, when more nutritious food such as ground squirrels are mainly fed to the young). It also breeds notably later than the other two species.England, A. S., Bechard, M. J., & Houston, C. S. (1997).

The last two known wild individuals of the Hawaiian crow disappeared in 2002, and the species is now classified as Extinct in the Wild by the IUCN Red List. While some 115 individuals remain (as of August 2014) in two captive breeding facilities operated by the San Diego Zoo, attempts to reintroduce captive-bred birds into the wild have been hampered by predation by the Hawaiian hawk (Buteo solitarius), which itself is listed as Near Threatened. Breeding efforts have also been complicated due to extensive inbreeding during the crow's population decline.

This morph comprises a majority of birds seen in passage east of the Mediterranean. Rufous morph buzzards are a paler grey-brown above than most nominate B. b. buteo. Compared to the nominate race, rufous vulpinus show a patterning not dissimilar but generally far more rufous-toned on head, the fringes to mantle wing coverts and, especially, on the tail and the underside. The head is grey-brown with rufous tinges usually while the tail is rufous and can vary from almost unmarked to thinly dark-barred with a subterminal band.

The survival probability, however, increases to age three, when it begins to decrease again. Females that survive to one year of age have a life expectancy of 2.3 years and a maximum lifespan of eight years. Increased maternal attention is correlated with increased offspring growth rate and higher lifetime reproductive success. Chief predators include the Canadian lynx (Lynx canadensis), bobcat (Lynx rufus), coyote (Canis latrans), great horned owl (Bubo virginianus), northern goshawk (Accipiter gentilis), red-tailed hawk (Buteo jamaicensis), American crow (Corvus brachyrynchos), American marten (Martes americana), red fox (Vulpes vulpes), gray fox (Urocyon cinereoargenteus), wolf (Canis lupus), and weasel (Mustela sp.).

A very large balance of the prey range can also be comprised by birds and other prey including reptiles, amphibians, fish, insects and other invertebrates are seemingly taken whenever they are available. All told, well more than 600 different species have been identified as prey of Eurasian eagle-owls. Their diet includes basically all the same prey as all sympatric diurnal raptors in the genera Buteo, Aquila and Haliaeetus. The total number of prey species may even surpass that of the great horned owl and may well be the greatest of any raptorial bird on the Eurasian continent.

In sometimes differing parts of the Arctic, competing predators for lemmings are, in addition to short-eared owls, pomarine jaegers (Stercorarius pomarinus), long-tailed jaegers (Stercorarius longicaudus), rough-legged buzzards (Buteo lagopus), hen harriers (Circus cyaenus), northern harriers (Circus hudsonius) and generally less specialized gyrfalcons (Falco rusticollis), peregrine falcons (Falco peregrinus), glaucous gulls (Larus hypoboreus) and common ravens (Corvus corax). Certain carnivorous mammals, especially the Arctic fox and, in this region, the ermine, are also specialized to hunt lemmings.Reid, D. G., Krebs, C. J., & Kenney, A. (1995). Limitation of collared lemming population growth at low densities by predation mortality. Oikos, 387–398.

At the same time, however, a new class of scholarship arose, one which, while never questioning the literal truth of the ark story, began to speculate on the practical workings of Noah's vessel from within a purely naturalistic framework. In the 15th century, Alfonso Tostada gave a detailed account of the logistics of the Ark, down to arrangements for the disposal of dung and the circulation of fresh air. The 16th-century geometer Johannes Buteo calculated the ship's internal dimensions, allowing room for Noah's grinding mills and smokeless ovens, a model widely adopted by other commentators.

Nests are known to be predated by coyotes (Canis latrans), golden eagles (Aquila chrysaetos), red-tailed hawks (Buteo jamaicensis), great horned owls (Bubo virginianus) and flocks of common ravens (Corvus corax), predators possibly too formidable to be fully displaced by the Harris's hawk's cooperative nest defenses. No accounts show predation on adults in the United States and the Harris's hawk may be considered an apex predator, although presumably predators like eagles and great horned owls would be capable of killing them.Dawson, J. W. and R. W. Mannan. (1991). Dominance hierarchies and helper contributions in Harris' Hawks.

However, dispersal has only been observed once with a young adult male, which left his natal group and proceeded to oust an older male from a group in which he had been a member for seven years. Female dispersal and group transfer has not yet been observed. The only documented predator of the silky sifaka, other than humans, is the fossa, a cat-like carnivore found only on Madagascar. Although no aerial predators are known, the silky sifaka often watches the sky and emits loud "aerial disturbance" roars at the sight of the large Madagascar buzzard (Buteo brachypterus) and other small birds.

This refers to the contrasting coloration when seen from below. When the black-chested buzzard-eagle was first described by Louis Jean Pierre Vieillot in 1819, it was placed in the genus Spizaetus, as Spizaetus melanoleucus. Nowadays, however, the monotypic genus Spizastur is merged in Spizaetus, and the black-and-white hawk-eagle, originally described as by Vieillot three years earlier as Buteo melanoleucus, is now known as Spizaetus melanoleucus. The earlier use of the specific epithet melanoleucus for the black-and-white hawk-eagle technically precludes its use for the black-chested buzzard-eagle, except when it is placed in Geranoaetus.

US Forest Service, Compiled by Robert G. Bailey, March 1995. Accessed 1 August 2020. The most common resident birds are the American bushtit (Psaltriparus minimus), pinyon jay (Gymnorhinus cyanocephalus), Woodhouse's scrub jay (Aphelocoma woodhouseii), juniper titmouse (Baeolophus ridgwayi), western red-shafted flicker (Colaptes auratus cafer), rock wren (Salpinctes obsoletus), black-chinned hummingbird (Archilochus alexandri), red-tailed hawk (Buteo jamaicensis), and golden eagle (Aquila chrysaetos). Summer-resident birds include the chipping sparrow (Spizella passerina), common nighthawk (Chordeiles minor), black-throated gray warbler (Setophaga nigrescens), American cliff swallow (Petrochelidon pyrrhonota), lark sparrow (Chondestes grammacus), and mourning dove (Zenaida macroura).

Intensive anthropogenic activity has also impacted the fauna of Pryingulsky RLP. Cattle pasture, recreational loads, amateur fishery, poaching in the area of Sofiivske water reservoir, steppe and forest fire deplete the fauna of RLP, which, however, is much better preserved than in the bordering agrolandscapes. The list of rare and threatened species being under protection of the State includes Southern Festoon (Zerynthia polyxena), Old World Swallowtail (Papilio machaon), Mammoth Wasp (Scolia maculata), Carpenter Bee (Xylocopa valga), Large Whip Snake (Coluber jugularis), Long-legged Buzzard (Buteo rufinus), Stoat or Ermine (Mustela erminea), Steppe Polecat (Mustela eversmanii) etc.

A high balance of bacterial flora were found the airways of 10 Cooper's hawks, including many with Salmonella (rarely fatal in hawks but can compromise their condition).Lamberski, N., Hull, A. C., Fish, A. M., Beckmen, K., & Morishita, T. Y. (2003). A survey of the choanal and cloacal aerobic bacterial flora in free-living and captive red-tailed hawks (Buteo jamaicensis) and Cooper's hawks (Accipiter cooperii). Journal of Avian Medicine and Surgery, 17(3), 131-135. 91% of 47 tested adults in Wisconsin had Leucocytozoon toddi and 62% had Haemoproteus but only 12% of 33 nestlings there had parasites.

For example, a previous reconstruction of migratory behaviour in one Buteo clade with a result of the origin of migration around 5 million years ago was also supported by that study. Migratory species of raptors may have had a southern origin because it seems that all of the major lineages within Accipitridae had an origin in one of the biogeographic realms of the Southern Hemisphere. The appearance of migratory behaviour occurred in the tropics parallel with the range expansion of migratory species to temperate habitats. Similar results of southern origin in other taxonomic groups can be found in the literature.

The breeding population in Greece is around 60 pairs. The African Long-legged Buzzard Buteo rufinus cirtensis has recently colonised Europe due to the climate in southern Europe becoming more suitable for this species. It is expected that the Iberian Peninsula will provide favourable breeding habitat for the African Long-legged Buzzard and facilitate its northward expansion through Europe. Reforestation in the Judean Mountains in Israel and the West Bank is displacing populations of the long-legged buzzard, and the species is moving into the Judean Foothills and competing with the short-toed snake eagle there.

These species have broadly similar breeding season diets, especially the ferruginous and red-tailed hawks. In some areas, such as Snake River NCA the diets of the two species consist of more than 90% of the same species and body mass of prey taken was similar. Therefore, all three large Buteo hawks defend their territories from each other with almost the same degree of dedication that they defend from others of their own species. In some cases, territorial clashes of Swainson's hawks and red-tailed hawks can last up to 12 hours, however, the birds involved are usually careful to avoid physical contact.

Kīlauea's northern lowland wet- forest ecosystem is partially protected by the Puna Forest Reserve and the Kahauale`a Natural Area Reserve. At , Wao Kele in particular is Hawaii's largest lowland wet forest reserve, and is home to rare plant species including hāpuu ferns (Cibotium spp.), 'ie'ie vines (Freycinetia arborea), and kōpiko (Psychotria mariniana), some of which play a role in limiting invasive species' spread. Opeapea (Lasiurus cinereus semotus) io (Buteo solitarius), common amakihi (Hemignathus virens), and nananana makakii (Theridion grallator) live in the trees. There are thought to be many more as-yet- undocumented species within the forest.

Aulus Atilius Calatinus (dead by 216 BC) was a politician and general in Ancient Rome. He was the first Roman dictator to lead an army outside Italy (then understood as the Italian mainland), when he led his army into Sicily. He was consul in 258 BC and again in 254, a praetor and triumphator in 257, and finally a censor in 247. Calatinus must have died by 216, because Marcus Fabius Buteo (censor in 241) was named the oldest living ex-censor; Calatinus would have been senior to him in terms of the date of censorship and their respective ages.

The diet of the fulvous harvest mouse varies seasonally, but in milder climates, consists primarily of insects and other invertebrates throughout the year, whereas in colder regions, invertebrates predominate in the spring, and seeds in the fall and winter. A small proportion of green leafy and other plant food is also eaten. Predators of this mouse include barn owls (Tyto alba) and red-tailed hawks (Buteo jamaicensis). In Mexico, breeding seems to take place throughout the year, but in Texas, usually two breeding peaks occur, one in late spring and the second a few months later.

Steppe buzzards are slightly gregarious in migration, and travel in variously sized flocks. This race migrates in September to October often from Asia Minor to the Cape of Africa in about a month but does not cross water, following around the Winam Gulf of Lake Victoria rather than crossing the several kilometer wide gulf. Similarly, they will funnel along both sides of the Black Sea. Migratory behavior of steppe buzzards mirrors those of broad-winged & Swainson's hawks (Buteo platypterus & swainsoni) in every significant way as similar long-distance migrating Buteos, including trans-equatorial movements, avoidance of large bodies of waters and flocking behaviour.

The Hawaiian hawk, which evolved on an isolated group of islands with no terrestrial mammals, was also initially a bird specialist although today it preys mainly on introduced rodents. Other prey may include snakes, lizards, frogs, salamanders, fish, and even various invertebrates, especially beetles. In several Buteo species found in more tropical regions, such as the roadside hawk or grey-lined hawk, reptiles and amphibians may come to locally dominate the diet. Swainson's hawk, despite its somewhat large size, is something of exceptional insect-feeding specialist and may rely almost fully on crickets and dragonflies when wintering in southern South America.Snyder, N. F. R. and J. W. Wiley. 1976.

Under the Servian Organization, the assembly was so aristocratic that the officer class and the first class of enlisted soldiers controlled enough centuries for an outright majority. In 241 BC, this assembly was reorganized by the Censors Marcus Fabius Buteo and Gaius Aurelius Cotta, in order to give more weight to the lower ranking centuries, and thus make the assembly less aristocratic.Abbott, 75 Under the old system, there were a total of 193 centuries, while under the new system, there were a total of 373 centuries. Under the new system, the thirty-five Tribes were each divided into ten centuries:Abbott, 74 five of older soldiers, and five of younger soldiers.

Accordingly, systematics declined in importance as a means to study birds. Birds named for Ridgway include the buff-collared nightjar, Caprimulgus ridgwayi (once known as Ridgway's whip- poor-will); the turquoise cotinga, Cotinga ridgwayi; the Caribbean subspecies of the osprey, Pandion haliaetus ridgwayi; a Big Island subspecies of the elepaio, Chasiempis sandwichensis ridgwayi; Ridgway's hawk, Buteo ridgwayi; Ridgway's Rail, Rallus obsoletus; and many other species and subspecies. The monotypic genus Ridgwayia is named for him; it consists of Aztec thrush, R. pinicola. In 1919, Ridgway was awarded the Daniel Giraud Elliot Medal from the National Academy of Sciences for his Birds of North and Middle America.

The Game Lands is dominated by deciduous and coniferous forest, with streams, herbaceous and unvegetated areas, 96.1% forested mostly hardwoods including oaks, also including mountain boulder fields. Hunting, trapping and furtaking opportunities include bear (Ursus americanus), Coyote (Canis latrans), Mourning dove (Zenaida macroura), deer (Odocoileus virgianus), Ruffed grouse (Bonasa umbellus), opossum (Didelphis virginiana), Common pheasant (Phasianus colchicus), rabbit (Sylvilgus floridanus), Raccoon (Procyon lotor), squirrel (Sciurus carolinensis), and turkey (Meleagris gallopavo). Birdwatching species of interest include Broad-winged hawk (Buteo platypeterus), Scarlet tanager (Piranga olivacea), Wood thrush (Hylocichla mustelina), Black-throated green warbler (Setophaga virens), Cerulean warbler (Setophaga cerulea), Worm-eating warbler (Helmitheros vermivorum), and Louisiana waterthrush (Parkesia motacilla).

Its primary diet is rabbits and hares, rats and mice, and voles, although it freely hunts any animal it can overtake, including rodents and other small mammals, larger mid-sized mammals, birds, reptiles, amphibians, and invertebrates. In ornithological study, the great horned owl is often compared to the Eurasian eagle-owl (Bubo bubo), a closely related species, which despite the latter's notably larger size, occupies the same ecological niche in Eurasia, and the red-tailed hawk (Buteo jamaicensis), with which it often shares similar habitat, prey, and nesting habits by day, thus is something of a diurnal ecological equivalent.Voous, K.H. 1988. Owls of the Northern Hemisphere.

The dictator's lieutenant was the magister equitum, or "master of the horse". He would be nominated by the dictator immediately upon his own appointment, and unless the senatus consultum specified the name of the person to be appointed, the dictator was free to choose whomever he wished. It was customary for the dictator to nominate a magister equitum even if he were appointed for a non-military reason. Before the time of Caesar, the only dictator who refused to nominate a magister equitum was Marcus Fabius Buteo in 216 BC, and he strenuously objected to his own nomination, because there was already a dictator in the field.

Birds of prey (order Accipitres) were divided into diurnal and nocturnal tribes; the owls remained monogeneric (family Ægolii, genus Strix), whilst the diurnal raptors were divided into three families: Vulturini, Gypaëti, and Accipitrini. Thus Veillot's families were similar to the Linnaean genera, with the difference that shrikes were no longer included amongst the birds of prey. In addition to the original Vultur and Falco (now reduced in scope), Veillot adopted four genera from Savigny: Phene, Haliæetus, Pandion, and Elanus. He also introduced five new genera of vultures (Gypagus, Catharista, Daptrius, Ibycter, Polyborus) and eleven new genera of accipitrines (Aquila, Circaëtus, Circus, Buteo, Milvus, Ictinia, Physeta, Harpia, Spizaëtus, Asturina, Sparvius).

Flying a saker falcon goshawk Falconry is the hunting of wild animals in their natural state and habitat by means of a trained bird of prey. Small and larger animals are hunted; squirrels and rabbits often fall prey to these birds. There are two traditional terms used to describe a person involved in falconry: a falconer flies a falcon; an Austringer (French origin) flies a hawk (Accipiter, some buteos and similar) or an eagle (Aquila or similar). In modern falconry, the red-tailed hawk (Buteo jamaicensis), the Harris's hawk (Parabuteo unicinctus), and the peregrine falcon (Falco perigrinus) are some of the more commonly used birds of prey.

Competitive and predatory interactions among raptors: an observational and experimental study. Ecology, 77(4), 1134-1142. Beyond goshawks, diurnal raptors in Europe known to be predators of long-eared owls of potentially any age are known to include golden eagle (Aquila chrysaetos), Bonelli's eagle (Aquila fasciata), eastern imperial eagle (Aquila heliaca), greater spotted eagle (Clanga clanga), lesser spotted eagle (Clanga pomarina), black kite (Milvus migrans), red kite (Milvus milvus), white-tailed eagle (Haliaeetus albicilla), common buzzard, rough-legged buzzard (Buteo lagopus), peregrine falcon (Falco peregrinus), saker falcon (Falco cherrug) and even (in two cases) the slightly smaller Eurasian sparrowhawk (Accipiter nisus).Mayor, J.R.

Some common wetland species seen today include the Beaver (Castor canadensis), River Otter (Lutra canadensis). Chinook, Coho, Sockeye and Kokanee salmon species have been observed, as well as Trout and Bass species. The wetland also hosts a variety of reptiles and amphibians, including the Pacific treefrog (Pseudacris regilla), Red-legged frog (Rana aurora), Bullfrog (Rana catesbeiana), Common garter snake (Thamnophis sirtalis), and the Northwestern garter snake (Thamnophis ordinoides). Bird species are also prevalent in the wetland restoration, common species include Great blue heron (Ardea Herodias), Canada goose (Branta Canadensis), Mallard duck (Anas platyrhynchos), Osprey (Pandion haliaetus), Red-tailed hawk (Buteo jamaincensis), and the American crow (Corvus brachyrhynchos).

Pale individuals are sometimes also mistaken with pale morph short-toed eagles (Circaetus gallicus) which are much larger with a considerably bigger head, longer wings (which are usually held evenly in flight rather than in a dihedral) and paler underwing lacking any carpal patch or dark wing lining. More serious identification concerns lie in other Buteo species and in flight with honey buzzards, which are quite different looking when seen perched at close range. The European honey buzzard (Pernis apivorus) is thought in engage in mimicry of more powerful raptors, in particular, juveniles may mimic the plumage of the more powerful common buzzard.Duff, D. (2006).

Usually the face also appears somewhat whitish in most pale morphs of rough-legged buzzards, which is true of only extremely pale common buzzards. Dark morph rough-legged buzzards are usually distinctly darker (ranging to almost blackish) than even extreme dark individuals of common buzzards in Europe and still have the distinct white-based tail and broad subterminal band of other roughlegs. In eastern Europe and much of the Asian range of common buzzards, the long-legged buzzard (Buteo rufinus) may live alongside the common species. As in the steppe buzzard race, the long-legged buzzard has three main colour morphs that are more or less similar in hue.

32 species of mammals inhabit the páramo, including shrews (Cryptotis), rabbits (Sylvilagus), ocelot (Leopardus pardalis), margay (Leopardus wiedii), puma (Puma concolor ssp. costaricensis), and Baird's tapir (Tapirus bairdii). 70 bird species have been observed in the páramo. Twelve are considered true páramo residents, who live year-round in the páramo – the red-tailed hawk (Buteo jamaicensis), black-cheeked warbler (Basileuterus melanogenys), wrenthrush (Zeledonia coronata), flame-throated warbler (Oreothlypis gutturalis), timberline wren (Thryorchilus browni), volcano hummingbird (Selasphorus flammula), black-billed nightingale-thrush (Catharus gracilirostris), sooty thrush (Turdus nigrescens), sooty-capped bush tanager (Chlorospingus pileatus), volcano junco (Junco vulcani), large-footed finch (Pezopetes capitalis), and rufous-collared sparrow (Zonotrichia capensis).

Fish species include Ictalurus punctatus (channel catfish), Stizostedion vitreum (walleye), Esox masquinongy (muskellunge), Morone chrysops (white bass), Ambloplites rupestris (rock bass), and Lepomis megalotis (longear sunfish). The availability of “seeds, berries, nuts, buds, flowers, fleshy roots and twigs” encourages the presence of species such as the Bonasa umbellus (ruffed grouse), Meleagris gallopavo (turkey), Sciurus carolinensis (eastern gray squirrel). Food available in canopy vegetation supports Vireo olivaceus (red-eyed vireo), Wilsonia citrina (hooded warbler), Setophaga ruticilla (American redstart), Sorex fumeus (smoky shrew), Scalopus aquaticus (eastern mole), Neotoma floridana (eastern woodrat), and Peromyscus leucopus (white-footed mouse). These species in turn provide food for predatory birds such as Strix varia (barred owl) and Buteo lineatus (red-shouldered hawk).

Rome had already consolidated its conquest of various peoples of northern Italy, and established good relations with the Adriatic Veneti. From there, Rome launched campaigns against the southern Illyrians of the Ardiaean Kingdom, and the northern Illyrians of the northern Adriatic and eastern Alps. Threatened by imminent loss of independence, Histria launched a first, indecisive attack against the Romans, in 221 BC. Another attack, in 181 BC at the new-founded colony of Aquileia, was beaten off by the Roman praetor Q. Fabius Buteo, who established a peace treaty with the Histrians. Later that year, Epulon became king of the Histrians; he was warlike, uncompromising and persistent, and immediately prepared for battle against the Aquilean colony.

Beak of Haliastur showing the characteristic circular nostril Plumage The brahminy kite is distinctive and contrastingly coloured, with chestnut plumage except for the white head and breast and black wing tips. The juveniles are browner, but can be distinguished from both the resident and migratory races of black kites in Asia by the paler appearance, shorter wings, and rounded tail. The pale patch on the underwing carpal region is of a squarish shape and separated from Buteo buzzards. The brahminy kite is about the same size as the black kite (Milvus migrans) and has a typical kite flight, with wings angled, but its tail is rounded unlike the Milvus species, red kite, and black kite, which have forked tails.

Conflicts over territories, food and nest- defense have been reported with several other large species of raptor, such as the great horned (Bubo virginianus) and short-eared owl (Asio flammeus), hen harrier (Circus cyaneus), red-tailed and Swainson's hawks (Buteo swainsonii), golden eagle (Aquila chrysaetos), accipiters (Accipiter), ravens (Corvus), and magpies (Pica). Among native raptorial birds, only larger eagles and similarly sized great horned owls can regularly outmatch this large and powerful hawk. While bald eagles (Haliaeetus leucocephalus) normally only harass ferruginous hawks to pirate food from them, the golden eagle can be a serious killer (in potential territorial or defensive conflicts) and predator of the ferruginous.Plumpton, D. L., & Andersen, D. E. 1997.

Giant mouse lemurs are often sympatric with mouse lemurs, such as M. murinus, though they are typically found higher in the canopy and favor thicker, taller gallery forests. At the Marosalaza forest (north of Morondava), Coquerel's giant mouse lemur is sympatric with four other nocturnal lemurs (mouse lemurs, sportive lemurs, dwarf lemurs, and fork-marked lemurs), but manages niche differentiation by feeding at different times and specializing on insect secretions during the dry season. Diurnal birds of prey such as the Madagascar buzzard (Buteo brachypterus) are their most significant predators. Other documented predators of giant mouse lemurs include the fossa (Cryptoprocta ferox), Madagascar owl (Asio madagascariensis), and the narrow- striped mongoose (Mungotictis decemlineata).

During winter their hunting habits may keep them somewhat separate, the rough-legged being a much more aerial hunter, but rough-legged buzzards usually withdrew if a red-tailed hawk flew towards them. There is at least one case, however, of a rough-legged buzzard being the victor of a conflict over a kill with a red-tailed hawk. Red-tailed hawks are conspicuously more aggressive and tend to be dominant over slenderer, medium-sized Buteos such as red-shouldered hawks and zone- tailed hawks (Buteo albonotatus). In Massachusetts, red-shoulder hawks used mixed forests and hardwoods as nesting habitat while red-tails most often used in pitch pine and stunted oaks on Cape Cod.

Chlorodrepanis virens) is one of the many birds that live on the volcano's flanks. Much of Kīlauea's southern ecosystem lies within the Hawaiʻi Volcanoes National Park, where a’e ferns, ʻōhiʻa trees (Metrosideros polymorpha), and hapu’u of the genus Cibotium are common. The park hosts a large variety of bird species, including the 'apapane (Himatione sanguinea); the 'amakihi (Hemignathus virens); the 'i'iwi (Vestiaria coccinea); the ‘ōma’o (Myadestes obscurus), the ʻelepaio (Chasiempis sp.); and the endangered 'akepa (Loxops coccineus), 'akiapola'au (Hemignathus munroi), nēnē (Branta sandvicensis), ʻuaʻu (Pterodroma sandwichensis), and ʻio (Buteo solitarius) species. The Kīlauea coast also hosts three of the nine known critically endangered hawksbill sea turtle (Eretmochelys imbricata) nesting sites on the island.

American robin, (Turdus migratorius) The arrival signals one of the first signs of spring. Typical birds of the Moist Mixed Grassland ecoregion include waterfowl around ponds and sloughs and the western meadowlark (Sturnella neglecta), yellow-headed blackbird (Xanthocephalus xanthocephalus), piping plover (Charadrius melodus), sharp-tailed grouse, eastern kingbird (Tyrannus tyrannus), and Franklin's gull. The Mixed Grassland in southern Saskatchewan features these characteristic birds ferruginous hawk Buteo regalis, long- billed curlew (Numenius americanus), yellow-breasted chat (Icteria virens), chestnut-collared longspur (Calcarius ornatus), burrowing owl (Athene cunicularia) and sage grouse (Centrocercus urophasianus). Characteristic birds of the Cypress Upland ecoregion are trumpeter swan (Cygnus buccinator), sage grouse, golden eagle (Aquila chrysaetos), yellow-rumped warbler, MacGillivray's warbler (Oporornis tolmiei), dusky flycatcher (Empidonax oberholseri) and Townsend's solitaire (Myadestes townsendi).

Marcus Fabius Buteo (died around 210 BC-209 BC) was a Roman politician during the 3rd century BC. He served as consul and as censor, and in 216 BC, being the oldest living ex-censor, he was appointed dictator, legendo senatui, for the purpose of filling vacancies in the senate after the Battle of Cannae. He was appointed by the consul Varro, and, with M. Junius Pera, he was the only dictator to serve a simultaneous term with another. He resigned from the post immediately after he revised the censors' lists and enrolled the new Senate members. By 210 BC to 209 BC, the censor Tuditanus among possible candidates for Princeps Senatus chose instead his kinsman Quintus Fabius Maximus Verrucosus.

In fact, in the mid-20th century Buteo fuscescens was the prevailing name for the black- chested buzzard-eagle for some years, but it was eventually dismissed as erroneous. This specific name was established – as Spizaetus fuscescens – by Vieillot for the immature of the black-chested buzzard-eagle at the very same time as he described the adult, because he could not believe that such differently-colored birds were conspecific. As the two birds are not placed in the same genus today, Article 59.3 of the ICZN Code applies. According to this, a junior homonym replaced before 1961 is not rendered permanently invalid (as junior homonyms usually are) if "the substitute name is not in use" – which has been the case after Amadon's 1963 revision.

Palm-nut vulture is an unusual frugivorous accipitrid, but will also consume fish, particularly dead fish Shikra Accipiter badius in Hyderabad, India Oriental honey-buzzard Pernis ptilorhyncus Accipitrids are predominantly predators and most species actively hunt for their prey. Prey is usually captured and killed in the powerful talons of the raptor and then carried off to be torn apart with a hooked bill for eating or feeding to nestlings. A majority of accipitrids are opportunistic predators that will take any prey that they can kill. However, most have a preference for a certain type of prey, which in harriers and the numerous buteonine hawks (including more than 30 species in the genus Buteo) tends towards small mammals such as rodents.

Bank vole carrying nest material The bank vole is plentiful during much of the year and plays an important part in the diet of various predators including the red fox (Vulpes vulpes), the stoat (Mustela erminea), the least weasel (Mustela nivalis), the European mink (Mustela lutreola), the common kestrel (Falco tinnunculus), the rough-legged buzzard (Buteo lagopus) and the tawny owl (Strix aluco). The voles try to prevent being caught by avoiding open areas of ground, by using tunnels and well-worn paths through the undergrowth. The bank vole acts as a reservoir of infection for the Puumala virus, which can infect humans, causing a haemorrhagic fever known as nephropathia epidemica and, in extreme cases, even death.Yeron Kalner (August 7, 2014) "Deadly Research," Retrieved Yedioth Ahronoth, p.

Unlike some other Buteos, such as Swainson's hawks and broad-winged hawks (Buteo platypterus), red-tailed hawks do not usually migrate in groups, instead passing by one-by-one, and will only migrate on days when winds are favorable. Most migrants do not go past southern Mexico in late autumn, but a few may annually move down as far as to roughly as far as there are breeding red-tailed hawks down in Panama. However, there are now a few records of wintering migrant red-tails turning up in Colombia, the first records of the species in that country or anywhere in South America. Spring northward movements may commence as early as late February, with peak numbers usually occurring in late March and early April.

Numerous passerine and songbirds such as the titmouse (Baeolophus bicolor), purple finch (Haemorhous purpureus), black-capped chickadee (Poecile atricapillus), jays/crows (family Corvidae), wren (family Troglodytidae), warbler (family Parulidae), dove (family Columbidae), woodpecker (family Picidae) and thrush (family Turdidae) have been spotted. Birds of prey encountered include owls, especially the barred owl (Strix varia), and hawks (mostly genus Buteo). Throughout the day, but most frequently during the crepuscular and predawn hours, the trill and tremolo of the common loon (Gavia immer) can be heard on the pond. Far less frequently encountered, but occasionally reported, are sights of black bear (Ursus americanus), North American porcupine (Erethizon dorsatum), white- tailed deer (Odocoileus virginianus), common raccoon (Procyon lotor), fisher (Pekania pennanti) and moose (Alces alces).

Studies of P. pallescens at Kirindy Forest found up to a 20% drop in body mass during the dry season despite no changes in exudate production, indicating flowers and insects have a significant impact on the species' health. Fork-marked lemurs are thought to be preyed upon by large owls, such as the Madagascar owl (Asio madagascariensis), and snakes like the Malagasy tree boa (Sanzinia madagascariensis). In one case, a family of fork- marked lemurs exhibited mobbing behavior when they encountered a Malagasy tree boa. Diurnal raptors, such as the Madagascar buzzard (Buteo brachypterus) and Madagascar cuckoo-hawk (Aviceda madagascariensis) hunt these lemurs at dusk, and the hunting behavior of the Madagascar harrier-hawk (Polyboroides radiatus) suggests it might extract them from their sleeping holes.

He might have been referred to the mentioned missing text. Richardson holds that a man with the cognomen Cento (usually written as Centho in the literary sources) is recorded in the Fasti Triumphales and that he may have been the praetor of Hispania Ulterior who succeed Titus Fontueus. Therefore, he must have won a battle, but there is no record of his activities.Richardson, Hispaniae, Spain and the Development of Roman Imperialism, 218–82 BC, pp. 103. The Fasti Triumphales is a list of triumphs form the foundation of Rome to 12 BC. In 173 BC, the praetors Numerius Fabius Buteo and Marcus Matienus were assigned Hispania Citerior and Ulterior respectively. They were reinforced by 3,000 Roman infantry and 200 cavalry.

A hawk eats a rock pigeon, near Toronto harbour Like most (but not all) Buteo hawks, red-tailed hawks do not primarily hunt birds in most areas, but can take them fairly often whenever they opportune upon some that are vulnerable. Birds are, by far, the most diverse class in the red-tailed hawk’s prey spectrum, with well over 200 species known in their foods. In most circumstances where birds become the main food of red-tailed hawks, it is in response to ample local populations of galliforms. As these are meaty, mostly terrestrial birds which usually run rather than fly from danger (although all wild species in North America are capable of flight), galliforms are ideal avian prey for red-tails.

Harris's hawk (Parabuteo unicinctus), formerly known as the bay-winged hawk or dusky hawk, and known in Latin America as peuco, is a medium-large bird of prey that breeds from the southwestern United States south to Chile, central Argentina, and Brazil. Birds are sometimes reported at large in Western Europe, especially Britain, but it is a popular species in falconry and these records almost certainly all refer to escapes from captivity. The name is derived from the Greek para, meaning beside, near or like, and the Latin buteo, referring to a kind of buzzard; uni meaning once; and cinctus meaning girdled, referring to the white band at the tip of the tail. John James Audubon gave this bird its English name in honor of his ornithological companion, financial supporter, and friend Edward Harris.

Found in the same range as the steppe buzzard in some parts of southern Siberia as well as (with wintering steppes) in southwestern India, the Oriental honey buzzard (Pernis ptilorhynchus) is larger than both the European honey buzzard and the common buzzard. The oriental species is with more similar in body plan to common buzzards, being relatively broader winged, shorter tailed and more amply-headed (though the head is still relatively small) relative to the European honey buzzard, but all plumages lack carpal patches. In much of Europe, the common buzzard is the only type of buzzard. However, the subarctic breeding rough-legged buzzard (Buteo lagopus) comes down to occupy much of the northern part of the continent during winter in the same haunts as the common buzzard.

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. 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 most celebrated stirps of the Fabia gens, which bore the surname Maximus, was in turn descended from the Fabii Ambusti. This family was famous for its statesmen and its military exploits, which lasted from the Samnite Wars, in the 4th century BC until the wars with the Germanic invaders of the 2nd century BC. Most, if not all of the later Fabii Maximi were descendants of Quintus Fabius Maximus Aemilianus, one of the Aemilii Paulli, who as a child was adopted into that illustrious family. Buteo, which described a type of hawk, was originally given to a member of the Fabia gens because such a bird on one occasion settled upon his ship with a favorable omen. This tradition, related by Plinius, does not indicate which of the Fabii first obtained this surname, but it was probably one of the Fabii Ambusti.

Some darker juveniles are similar enough to other Buteo juveniles that it has been stated that they "cannot be identified to species with any confidence under various field conditions." However, field identification techniques have advanced in the last few decades and most experienced hawk-watchers can distinguish even the most vexingly plumaged immature hawks, especially as the wing shapes of each species becomes apparent after seeing many. Harlan’s hawks are most similar to dark morph rough-legged buzzards and dark morph ferruginous hawks. Wing shape is the most reliable identification tool for distinguishing the Harlan’s from these, but also the pale streaking on the breast of Harlan’s, which tends to be conspicuous in most individuals, and is lacking in the other hawks. Also dark morph ferruginous hawks do not have the dark subterminal band of a Harlan’s hawk but do bear a black undertail covert lacking in Harlan’s.

While research shows a literal Noah's Ark could not be practical, nor is there geologic evidence of a biblical global flood, commentators throughout history have made attempts to demonstrate the Ark's existence. The first edition of the Encyclopædia Britannica from 1771 describes the Ark as factual. It also attempts to explain how the Ark could house all living animal types: "... Buteo and Kircher have proved geometrically, that, taking the common cubit as a foot and a half, the ark was abundantly sufficient for all the animals supposed to be lodged in it ... the number of species of animals will be found much less than is generally imagined, not amounting to a hundred species of quadrupeds". It also endorses a supernatural explanation for the flood, stating that "many attempts have been made to account for the deluge by means of natural causes: but these attempts have only tended to discredit philosophy, and to render their authors ridiculous".

In the Great Basin, the owls share black-tailed jackrabbit and desert cottontail as the primary prey with golden eagles, red-tailed hawks and ferruginous hawks (Buteo regalis); all four species had diets with more than 90% of the biomass is made up of those lagomorphs. Of these, the great horned owl and golden eagle were able to nest most closely to one another because they had the most strongly dissimilar periods of activity. In California, when compared to the local red-tailed hawks and western diamondback rattlesnakes (Crotalus atrox), the diets were most similar in that by number about 15-20% of all three species' diets depended on cottontails, but the largest portion was made up of ground squirrels in the hawk and the rattlesnake and desert woodrats and other assorted rodents in the great horned owl. In the boreal forests, the great horned owl's prolificacy as a snowshoe hare hunter places it second only to the Canada lynx (Lynx canadensis) among all predators.

Some biologists feel that long-eared owls tendency to avoid richer prey concentrations in favor of opener habitats and spatial usage, especially while migrating and wintering, is partial dictated by the detection of eagle-owl (and perhaps goshawk) activity, so therefore the eagle-owl has a serious influence on the long-eared owl's life history. In general, long-eared owls endure predation by a formidable array of diurnal birds of prey in Europe. It is likely that largely perch hunting raptor such as Buteo and most eagles may either chance upon an owl roost during a hunting foray or encounter a long-eared owl perhaps during overlapping activity around dawn or dusk, while large falcons are likely to only strike one down when an owl is flushed during daytime. Goshawks and other Accipiter hawks are a particularly deadly threat among diurnal raptors due to their intensive searching hunting methods and willingness to dive into wooded thickets holding roosting owls.

It is aggressive and will defend rich food sources from other nectarivores; due to its size, it is generally dominant over other species of hummingbirds. Even much larger birds are attacked by diving at them when they perch; particularly when breeding the swallow-tailed hummingbird will go and "dive-bomb" birds twice its own length or more, such as Campo flickers (Colaptes campestris), curl-crested jays (Cyanocorax cristatellus) or smooth-billed anis (Crotophaga ani), until they have enough and leave. Disturbed by much larger birds such as Guira cuckoos (Guira guira) or hawks, it will usually just give warning calls, but a female swallow-tailed hummingbird has been observed to attack a Swainson's hawk (Buteo swainsonii) - weighing more than a hundred times as much as the hummingbird - in mid-air. Warning calls are also given at mammalian carnivores and humans, though in urban environment this hummingbird may tolerate human observers for prolonged time, even when nesting, if they keep a distance of 10 meters or so.
