Population statistics

Vulture refers to 23 species of scavenging birds of the order Accipitriformes, comprising two families distantly related to each other: the New World vultures of the family Cathartidae, and the Old World vultures of the family Accipitridae, whose relatives include eagles, hawks, and kites.

Description[edit]

Vultures range in size from the crow-sized Egyptian vulture to the very large condors of the Americas, among the largest living flying birds. With few exceptions, vultures possess a head and neck devoid of feathers, enabling them to reach well inside animal carcasses without matting their feathers with blood. They have weak feet, adapted for walking rather than killing prey. Their wings are large and broad, which they use for effortless soaring. Eyesight is powerful in all species, and they can locate a carcass up to a mile away, while in a few New World species the sense of smell is also used, a rarity among birds.

Apart from Australia and many oceanic islands, vultures are worldwide, found generally in the tropics, with a few species ranging into temperate zones. They are open-country birds, spending hours aloft soaring on thermal updrafts to locate a dead or dying animal; when found a large flock will quickly gather, often from miles away. A social order takes place on the carcass, with the birds bearing the largest size feeding first, followed by the smaller birds. All give way, however, to any mammal scavenger who comes upon the carcass, such as hyenas and jackals.

Old World vultures build nests, usually large, and sometimes in large colonies, laying a single egg. New World vultures lay as much as two eggs in tree or cliff cavities, with none nesting in a colony.

Species[edit]

New World vultures[edit]

Found in the Americas, these birds are characterized from Old World vultures via a perforated nasal septum and by a reliance on scent in some species to find a carcass. All lack a syrinx, i.e. they are not vocal. Five genera, seven species:

• Genus Cathartes

Greater yellow-headed vulture, Cathartes melambrotus

Lesser yellow-headed vulture, Cathartes burrovianus

Turkey vulture, Cathartes aura

• Genus Coragyps

Black vulture, Coragyps atratus

• Genus Gymnogyps

California condor, Gymnogyps californianus

• Genus Sarcoramphus

King vulture, Sarcoramphus papa

• Genus Vultur

Andean condor, Vultur gryphus

Old World vultures[edit]

Found in Europe, Africa, and Asia, these birds rely on sight to find carrion; they are further characterized from New World vultures by the presence of a feathered neck and head in some species. Two subfamilies, nine genera, sixteen species:

• Subfamily Aegypiinae
  • Genus Aegypius

Eurasian black vulture, Aegypius monachus

• • Genus Gyps

Cape griffon vulture, Gyps coprotheres

Griffon vulture, Gyps fulvus

Himalayan griffon vulture, Gyps himalayensis

Long-billed vulture, Gyps indicus

Rüppell's vulture, Gyps rueppelli

Slender-billed vulture, Gyps tenuirostris

White-backed vulture, Gyps africanus

Indian white-rumped vulture, Gyps bengalensis

• • Genus Necrosyrtes

Hooded vulture, Necrosyrtes monachus

• • Genus Sarcogyps

Red-headed vulture, Sarcogyps calvus

• • Genus Torgos

Lappet-faced vulture, Torgos tracheliotus

• • Genus Trigonoceps

White-headed vulture, Trigonoceps occipitalis

• Subfamily Gypaetinae
  • Genus Gypaetus

Lammergeier, Gypaetus barbatus

• • Genus Gypohierax

Palm-nut vulture, Gypohierax angolensis
