Griffon Vulture

Light sandy-brown color. Weight is about 15 pounds. Has an eight-foot wing span, but short legs with weak, blunt toes. The horn-colored beak is slender and relatively weak. The long goose-like neck is thinly covered with down, with a distinct ruff of quill and down feathers at the base of the neck. Tail is rounded.

Widely distributed around the Mediterranean, ranging east into India and south across the savannas of Africa. Sometimes found as far north as the Scandinavian countries. Prefers barren areas with few trees, mountain steppes and high plateaus.

The friendliest and most social of the vultures. Non-territorial. There is some indication that pairs mate for life. They are "home" bodies and do not migrate. Nests are always placed on cliffs even when trees are available. They are built of twigs and grass and much excrement, often on the remains of previous years' nests and are found in a variety of sites, from well-protected rock caves to exposed ledges. 10-15 pairs may share nesting grounds. A single egg is hatched, occasionally two. Incubation period is unusually long, between 48-50 days. Young are covered with pale buffy down; when they leave the nest after 3-4 months they look almost like adults. Life span is 40 years.
