胡兀鹫（拉丁文学名：Gypaetus barbatus）是胡兀鹫属中唯一的成员。牠们一般会选择分布在南欧洲、非洲、印度和**的高山上生蛋，而牠们每次大约能生下一至两颗蛋。牠们通常会选择在冬天生蛋，因为这样做牠们所生的蛋才可以赶上在春天孵化。虽然人们已成功的从阿尔卑斯山引入胡兀鹫，但是胡兀鹫在欧洲仍然是一种非常稀有的猛禽。

虽然胡兀鹫不喜欢吃动物的尸体，但牠们会以一些骨髓做为日常食物的一部分。牠们还会从高空把骨头丢下，然后再从地上取得那些骨头的碎片。牠们也因为这种习惯而得到骨头压碎机（Bone Crusher）的名称。

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.
