Bearded vulture : ウィキペディア英語版 | Bearded vulture
The bearded vulture (''Gypaetus barbatus''), also known as the lammergeier or ossifrage, is a bird of prey and the only member of the genus ''Gypaetus''. Traditionally considered an Old World vulture, it actually forms a minor lineage of Accipitridae together with the Egyptian vulture (''Neophron percnopterus''), its closest living relative. It is not much more closely related to the Old World vultures proper than to, for example, hawks, and differs from the former by its feathered neck. Although dissimilar, the Egyptian and bearded vulture each have a lozenge-shaped tail — unusual among birds of prey. In July 2014, the IUCN Red List has reassesed this species to be near threatened. Before July 2014, it was actually classed as Least Concern. Their population trend is decreasing. The bearded vulture eats mainly carrion and lives and breeds on crags in high mountains in southern Europe, the Caucasus, Africa, the Indian subcontinent, and Tibet, laying one or two eggs in mid-winter that hatch at the beginning of spring. Populations are resident. == Distribution and habitat == The bearded vulture is sparsely distributed across a considerable range. It may be found in mountainous regions from Europe through much of Asia and Africa. In Eurasia, it is found in the Pyrenees, the Alps, the Caucasus region, the Zagros Mountains, the Alborzs, the Altai Mountains, the Himalayas,Ladakh in north India, western and central China, Israel (although the bird has been declared extinct in Israel for the past few decades, unconfirmed sightings have been reported in 2000 as well as 2004) and the Arabian Peninsula. In Africa, it is found in the Atlas Mountains, the Ethiopian Highlands and down from Sudan to northeastern Democratic Republic of the Congo, central Kenya and northern Tanzania. An isolated population inhabits the Drakensberg of South Africa. This species is almost entirely associated with mountains and inselbergs with plentiful cliffs, crags, precipices, canyons and gorges. They are often found near alpine pastures and meadows, montane grassland and heath, steep-sided, rocky wadis, high steppe and are occasional around forests. They seem to prefer desolate, lightly-populated areas where predators who provide many bones, such as wolves and golden eagles, have healthy populations. In Ethiopia, they are now common at refuse tips on the outskirts of small villages and towns. Although they occasionally descend to , bearded vultures are rare below an elevation of and normally reside above in some parts of their range. They are typically found around or above the tree line which are often near the tops of the mountains, at up to in Europe, in Africa and in central Asia. They even have been observed living at altitudes of on Mount Everest and been observed flying at a height of .〔〔〔〔
