The
Egyptian vulture (
Neophron percnopterus), also called the
white scavenger vulture or
pharaoh's chicken, is a small
Old World vulture and the only member of the
genus Neophron. It is widely distributed; the Egyptian vulture is found from southwestern
Europe and northern
Africa to
India. The contrasting underwing pattern and wedge-shaped tail make it distinctive in flight as it soars in thermals during the warmer parts of the day. Egyptian vultures feed mainly on
carrion but are opportunistic and will prey on small mammals, birds, and reptiles. They also feed on the eggs of other birds, breaking larger ones by tossing a large pebble onto them. The use of tools is rare in birds and apart from the use of a pebble as a hammer, Egyptian vultures also use twigs to roll up wool for use in their nest. Egyptian vultures that breed in the temperate regions migrate south in winter while tropical populations are relatively sedentary. Populations of this species have declined in the 20th century and some island populations are endangered by hunting, accidental poisoning, and collision with power lines.
