Griffon Vulture
Gyps fulvus
The griffon vulture is 93–122 cm (37–48 in) long with a 2.3–2.8 m (7.5–9.2 ft) wingspan. In the nominate race the males weigh 6.2 to 10.5 kg (14 to 23 lb) and females typically weigh 6.5 to 10.5 kg (14 to 23 lb), while in the Indian subspecies (G. f. fulvescens), the vultures average 7.1 kg (16 lb). Extreme adult weights have been reported from 4.5 to 15 kg (9.9 to 33.1 lb), the latter likely a weight attained in captivity. Hatched naked, it is a typical Old World vulture in appearance, with a white head, broad wings and short tail feathers. It has a white neck ruff and yellow bill.

The underside and under-wing coverts are pale brown or buff, almost white in some individuals. The whitish down on the head of immatures changes to yellowish in adults who have a long and pale brown ruff with white streaks and long and spiky ruff feathers.
