The Himalayan vulture or Himalayan griffon vulture (Gyps himalayensis) is an Old World vulture in the family Accipitridae. Closely related to the European griffon vulture (G. fulvus) and once considered a subspecies of it, this species is found along the Himalayas and the adjoining Tibetan Plateau. It is one of the two largest Old World vultures and true raptors.
The Himalayan vulture has dark brown greater covert feathers, tail and wing quills, but a pale buff uniform upperside and paler tipped inner secondaries; its legs are covered with buffy feathers and vary in colour from greenish grey to pale brown. 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.[5]
