Dr. Farine agrees that the vulturine guineafowl might not be all that unusual.
|
|
Scientists discovered that vulturine guineafowl live in multilevel societies reminiscent of our own.

She notes that baboon groups may also come together to sleep, like the vulturine guineafowl.
|
|
But as Dr. Farine studied baboons, he also watched the vulturine guineafowl wandering around his study site.
|
|
Like other species, Farine said that the vulturine guinea fowl survival was heavily reliant on living in groups.
|
|
And while most other social birds are very territorial, Dr. Farine says, groups of vulturine guineafowl don't mind sharing turf.

Tracking the vulturine guinea fowl took place at the Mpala Research Centre and Wildlife Foundation in Laikipia District, central Kenya.
|
|
So he and his colleagues began an intensive study of vulturine guineafowl society at the Mpala Research Center in Nanyuki, Kenya.
|
|
A study published Monday in Current Biology shows that the vulturine guineafowl of eastern Africa, like humans, have many-layered societies.
|
|
Puffins have been observed using tools, and vulturine guinea fowls in Kenya have been found to display complex social behavior more typically found in mammals.

Tanure's Société Mondiale fought back against the creditors' criticism in an emailed statement, calling their demands "vulturine, unreasonable and greedy" and accusing them of making a hostage out of the Brazilian government.
|
|
But a new study shows that vulturine guinea fowl, a bird with distinctive blue plumage that lives in Africa, can keep track of relationships with hundreds of others -- challenging the prevailing view that big brains are a requirement for complex society.

It is considered near threatened by BirdLife International (and consequently IUCN) due to the widespread deforestation of the Amazon. This parrot was initially believed to be a juvenile of the vulturine parrot due to the orange coloration of its bald head as opposed to the black of the vulturine. However, when it was discovered that the individuals were sexually mature, they were described as a new species. In reality, juveniles of both species have feathered, greenish heads quite unlike those of the adults.

The vulturine guineafowl is a gregarious species, forming flocks outside the breeding season typically of about 25 birds. This species' food is seeds and small invertebrates. This guineafowl is terrestrial and will run rather than fly when alarmed. Despite the open habitat, it tends to keep to cover, and roosts in trees.

Their anonymous critic excitedly wondered "what bitter irony it expresses, what hardened skepticism, sarcasm and ... pronounced cynicism".Shelton (1999), 304–5 Several critics mentioned Bertin's hands. Twentieth-century art historian Albert Boime described them as "powerful, vulturine ... grasping his thighs in a gesture ... projecting ... enormous strength controlled". Some contemporary critics were not so kind.

The reserve is home to several endangered species including the giant anteater (Myrmecophaga tridactyla), bush dog (Speothos venaticus) and swallow-tailed kite (Elanoides forficatus). A total of 193 bird species have been recorded, including the endangered Kawall's amazon (Amazona kawalli), golden parakeet (Guaruba guarouba), orange-cheeked parrot (Pyrilia barrabandi), vulturine parrot (Pyrilia vulturina) and golden-crowned manakin (Lepidothrix vilasboasi).

The vulturine guineafowl (Acryllium vulturinum) is the largest extant species of guineafowl. Systematically, it is only distantly related to other guineafowl genera. Its closest living relative, the white breasted guineafowl, Agelastes meleagrides inhabit primary forests in Central Africa. It is a member of the bird family Numididae, and is the only member of the genus Acryllium.

Wildlife species are displayed in open air enclosures. Each enclosure is landscaped individually to simulate the natural habitat of the species kept there. Peafowls roam freely in the main park area. Other birds include common pheasant, rose-ringed parakeet, ostrich, black swan, mute swan, silver pheasant, vulturine guineafowls, dalmatian pelican and many other types of water birds.

The raptors of Europe and the Middle East: a handbook of field identification. London: T & AD Poyser. Their neck is at times unexceptedly long-looking, more so than the bald eagle, which can give the upper body a vulturine appearance. The tail is relatively short, in some adults it can appear almost strangely so in relation to the massive body, and slightly wedge-shaped.

Their breast muscles are dark, enabling them to sustain themselves in flight for considerable distances if hard-pressed. Grass and bush fires are a constant threat to these galliformes and flight is the most effective escape. Some species of guineafowl, like the vulturine, may go without drinking water for extended periods, instead sourcing their moisture from their food. Young guineafowl (called keets) are very sensitive to weather, in particular cold temperatures.

A black rhinoceros population has been re-introduced into the park after an absence of 25 years due to heavy poaching. There are over 350 species of bird. These include grey-headed kingfisher, sunbirds, bee-eaters, Marabou stork, tawny eagle, Verreaux's eagle, bateleur, vulturine guineafowl, yellow-necked spurfowl, lilac-breasted roller, secretary bird, superb starling, northern red-billed hornbill, yellow- billed hornbill, and various vultures including the palm-nut vulture. The Ewaso Ng'iro river contains large numbers of Nile crocodile basks.

Guineafowl species are found across sub-Saharan Africa, some almost in the entire range, others more localized, such as the plumed guineafowl in west-central Africa and the vulturine guineafowl in north-east Africa. They live in semi-open habitats such as savanna or semideserts, while some, such as the black guineafowl, mainly inhabit forests. Some perch high on treetops. The helmeted guinea fowl has been introduced in East Africa, the West Indies, the United States, Britain, and India, where it is raised as food or pets.

Upper body At Tsavo East National Park, Kenya The vulturine guineafowl is a large (61–71 cm) bird with a round body and small head. It has a longer wings, neck, legs and tail than other guineafowl. The adult has a bare blue face and black neck, and although all other guineafowl have unfeathered heads, this species looks particularly like a vulture because of the long bare neck and head. The slim neck projects from a cape of long, glossy, blue and white hackles.

Notes on Sanford's Sea- Eagle Haliaeetus sanfordi and Other Raptors in the Solomon Islands. Australian Field Ornithology, 17(2). Outside of the genus Haliaeetus, among other extant forms, they appear to be most closely related to milvine kites and Old World vultures, based on modern forms from these subfamilies that broadly share morphological and life history traits with sea eagles: the Brahminy kite (Haliastur indus) (historically sometimes referred to as the “red-backed sea eagle”) and the palm-nut vulture (Gypohierax angolensis) (which was once widely referred to as the “vulturine fish eagle”).

Some Galliformes are adapted to grassland habitat, and these genera are remarkable for their long, thin necks, long legs, and large, wide wings. Fairly unrelated species like the crested fireback (Lophura ignita), vulturine guineafowl (Acryllium vulturinum), and malleefowl (Leipoa ocellata) are outwardly similar in their body types (see also convergent evolution). Most species that show only limited sexual dimorphism are notable for the great amount of locomotion required to find food throughout the majority of the year. Those species that are highly sedentary but with marked ecological transformations over seasons exhibit marked distinct differences between the sexes in size and/or appearance.

The insect- and seed-eating, ground-nesting birds of this family resemble partridges, but with featherless heads, though both members of the genus Guttera have a distinctive black crest, and the vulturine guineafowl has a downy brown patch on the nape. Most species of guineafowl have a dark grey or blackish plumage with dense white spots, but both members of the genus Agelastes lack the spots. While several species are relatively well known, the plumed guineafowl and the two members of the genus Agelastes remain relatively poorly known. These large birds measure from 40–71 cm (16–28 inches) in length, and weigh 700–1600 grams or 1.5-3.5 pounds.

Arthropods formed 13% and the remainder was from nectar, insects, and other berries. The only other known frugivore with a similar degree of dietary specialization is Pesquet's parrot (or vulturine parrot) of New Guinea that feeds almost exclusively on strangler figs. In becoming frugivore specialists, both these birds live off the fruit of parasites that germinate in the canopy of host trees, where the fruit of the parasite has specific seed placement requirements on host branches and resists consumption by frugivore nonspecialist birds. The mistletoe plant minimizes opportunistic consumption of their berries by less specialized dispersal birds by producing few, inconspicuous fruits over a long period.

The closely related African fish eagle (Haliaeetus vocifer) (from far outside the bald eagle's range) also has a brown body (albeit of somewhat more rufous hue), white head and tail, but differs from the bald in having a white chest and black tip to the bill. Head details The plumage of the immature is a dark brown overlaid with messy white streaking until the fifth (rarely fourth, very rarely third) year, when it reaches sexual maturity. Immature bald eagles are distinguishable from the golden eagle (Aquila chrysaetos), the only other very large, non-vulturine raptorial bird in North America, in that the former has a larger, more protruding head with a larger beak, straighter edged wings which are held flat (not slightly raised) and with a stiffer wing beat and feathers which do not completely cover the legs. When seen well, the golden eagle is distinctive in plumage with a more solid warm brown color than an immature bald eagle, with a reddish-golden patch to its nape and (in immature birds) a highly contrasting set of white squares on the wing.
