The bearded vulture, also known as the lammergeier and ossifrage, is a very large bird of prey in the monotypic genus Gypaetus. The bearded vulture is the only known vertebrate whose diet consists of 70–90% bone.
Region
Afro-Eurasian mountains
Typical Environment
Found in high mountain ranges including the Pyrenees, Alps, Caucasus, Ethiopian Highlands, East African mountains, Himalayas, and across Central Asia. Prefers rugged terrain with cliffs for nesting and open alpine or subalpine slopes for foraging. It frequents gorges and escarpments where updrafts aid soaring. In Europe it persists patchily but has benefited from reintroduction efforts in the Alps.
Altitude Range
500–4500 m

Also called the lammergeier or ossifrage, it is the only known vertebrate whose diet is composed mostly of bone, often 70–90%. It drops large bones from height onto rocks to shatter them and access the nutritious marrow. Adults often show a rusty-orange wash on the underparts, caused by deliberate bathing in iron-rich soils. Its long wedge-shaped tail and narrow wings give it a distinctive silhouette among vultures.
