Bearded Vulture (Gypaetus barbatus)


Scientific Classification

Kingdom: Animalia

Phylum: Chordata

Class: Aves

Order: Accipitriformes

Family: Accipitridae

Genus: Gypaetus

Species: Bearded vulture

Description

The distribution range includes  Southern Europe, Asia, the Caucasus (including Armenia), Africa, some parts of India, Tibet. The body length is 94-125 cm, the wingspan is 2.31-2.83 cm. Bearded vultures are variably orange or rust on their head, breast and leg feathers. The tail feathers and wings are gray. Full maturity takes up to five years.

Reproduction

Bearded vulture lives and breeds on crags in high mountains in southern Europe, Asia, the Caucasus (including Armenia) ; this species occupies an enormous territory

Diet

Eighty percent of the bird's diet consists of bone and bone marrow. Its stomach acid has a pH of about 1, so the dense material can be digested in under 24 hours. The Lammergeier is a scavenger; after finding a picked-over carcass, the bird will drop it from a tremendous height to shatter it into swallow-able pieces. Bearded vultures even have favorite breaking spots like ossuaries.

Reproduction

Bearded Vultures are most commonly monogamous, and breed once a year. Sometimes, especially in certain areas of Spain and France, bachelor lammergeiers will join a pre-existing couple to create a polyandrous trio. Females accept secondary mates because it increases the chances of producing offspring and doubles her protection.

Conservation Status

It is listed as “Least Concern” species according to IUCN Red List since 2014. Their population trend is decreasing. The vultures were completely eradicated from most areas in Eastern Europe by the 1990s.  The main causes of on-going declines appear to be non-target poisoning, habitat degradation, disturbance of breeding birds, inadequate food availability. In Europe, captive breeding and reintroduction programmes have been carried out which ensured stable populations.
