Aegypiinae is a subfamily of birds of prey of the family Accipitridae, consisting of six genera and thirteen species of vulture found over much of Africa, Europe, and Asia.

Description

The Old World vultures range in size from 37 to 44 inches in length, with wingspans up to 8.9 feet. They possess a head and neck devoid of feathers, replaced instead with a light, thin down, 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.

Old World vultures are 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.
