Griffon Vulture

Order: Falconiformes.

Family: Accipitridae. (Old World vulture).

Scientific Name: Gyps fulvus.

Common Names: Eurasian Griffon or Griffon Vulture.

Conservation Status: Threatened. Reduction in numbers due primarily to a lack of food. Still reasonably abundant in Spain; virtually extinct in Sicily. Balkan numbers have also diminished greatly.
The Griffon Vulture is 93–110 cm (37–43 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 11.3 kg (14 to 25 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 lb), the latter likely a weight attained in captivity.[2] Hatched naked, it is a typical Old World vulture in appearance, with a very white head, very broad wings and short tail feathers. It has a white neck ruff and yellow bill. The buff body and wing coverts contrast with the dark flight feathers.

Like other vultures, it is a scavenger, feeding mostly from carcasses of dead animals which it finds by soaring over open areas, often moving in flocks. It grunts and hisses at roosts or when feeding on carrion.

The maximum lifespan recorded for the Griffon Vulture is 41.4 years, for a specimen in captivity.[3]

It breeds on crags in mountains in southern Europe, north Africa, and Asia, laying one egg. Griffon Vultures may form loose colonies. The population is mostly resident.
