Identification

The Eurasian Griffon Vulture is 95-110 cm (37-43 in) long with a 230-265 cm (91-105 in) wingspan, and it weights between 6 and 13 kg (13.2 and 29 lbs). It is a typical Old World vulture in appearance, with a white bald head, very broad wings and a short tail. It has a white neck ruff and yellow bill. The buff body and wing coverts contrast with the dark flight feathers.

Distribution

Eurasia and North Africa. Formerly far more widespread in Europe, today found mainly around the Mediterranean and Black Seas, but still declining everywhere except Spain. The bulk of the Western Palearctic population breeds in Spain and occurs over most of the country except the north-west corner and most of the Mediterranean coast. It is now rare in Portugal but is still found in eastern parts close to the Spanish border. In France now confined to the Pyrenees and in the Cevennes where a small population is established as part of a reintroduction programme. Small numbers of non-breeders summer in the Alps and a released pair have bred in Austria.

The species is also found in scattered pockets in Morocco and northern Algeria, in Sardinia and in the former Yugoslavia and Bulgaria. Greece still has a few hundred pairs mainly in mountainous areas and on the island of Crete. Also found throughout much of Turkey and in scattered pockets in Syria and Israel. Very small numbers survive in the Crimea and the Caucasus and less than fifty are now present on Cyprus. Range extends eastwards from northern Iran to Central Asia and south to the Himalayas and north-west India.

Most adults are resident but immatures may wander or move southwards in autumn. Small numbers are regular at Gibraltar in July-November and the Bosphorus in September-October, with a return movement in April-May. Wandering birds have occurred in various European countries north to Ireland, Scandinavia, Poland and Germany but vagrancy is now much less frequent. However, with increasing protection and reintroductions underway this trend may be reversed and there have been recent records in Belgium and the Netherlands (including flocks of eighteen in July 2001 and fifteen in May 2002), Sweden and Finland and, in August 2000 one was present in the Channel Islands. The record of two birds in Derbyshire, England, in 1927 is now rejected and the species is no longer on the British List.

Taxonomy

Subspecies: Two races are recognised: the nominate across most of range with fulvescens in Afghanistan and north-west India.

Habitat

It is found in mountainous and open country where thermals occur. Requires carrion from livestock or herds of wild ungulates.

Behaviour

Diet

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.

Breeding

Nests colonially on cliff ledges.

Vocalisation

It grunts and hisses at roosts or when feeding on carrion.
