| Gypaetus barbatus|
G. b. barbatus
|Range of G. barbatus|
Lammergeier or Lammergeyer.
Length is 100–115 centimetres (39–45 in). Huge and long-winged. In strong light, when upperparts look pale and merge with mountainside, often best spotted by dark shadowing moving over the ground .
Adult: underbelly light, whitish with a varying degree of buffish-yellow or often rather deep rufous-buff tinge (acquired through sand-bathing!), contrasting with its dark underwing . In good light, lesser and median under-wing-coverts are darkest, being jet-black. Upperparts are lead-grey with pale feather shafts .
Females are larger than males .
Juvenile: Body is dull grey with contrasting dark grey head, neck and upper breast (like that of a Hooded Crow). Upperparts are not uniformly dark with lighter shafts (as on the adult birds) but are variegated; mantle, rump and some wing-coverts light .
Immature: Adult pattern is attained in about five years, subadults keeping the dark head rather long .
It can eat parts of the carcass that other birds cannot digest, including bones, which it smashes by dropping them onto rocks from the air . The food it always scavenges always contains bones and it will discard the flesh, preferring to extract the marrow . It also drops live tortoises on rocks .
Usually silent; but during aerial displays at breeding sites, utters shrill, loud whistling notes or a trill .
Its nest is a platform of twigs with central hollow lined with grass, hair, skin, and bones, in a cave or on a cliff ledge .
