The Bearded Vulture is the only known animal whose diet is almost exclusively bone marrow (70-90%).
This is the only living bird species that specializes in feeding on bone marrow.
The Bearded Vulture can swallow whole or bite through brittle bones up to the size of a lamb's femur and its powerful digestive system quickly dissolves even large pieces.
The Bearded Vulture has learned to crack bones too large to be swallowed by carrying them in flight to a height of 50–150 m above the ground and then dropping them onto rocks below, which smashes them into smaller pieces and exposes the nutritious bone marrow.
Unlike most vultures, the bearded vulture does not have a bald head.
In addition, it is together with the Egyptian Vulture the only bird of prey with a wedge-shaped tail.
