The Lammergeier, or Bearded Vulture, is found in the high country across southern Europe, Africa and India. She typically is found above the tree line. Her diet is carrion, although she favours bone marrow over flesh - the only bird species specialised for this diet. Her digestive system quickly digests the bone and she can crush pieces up to the size of a lamb's femur. Larger pieces are carried up into the air, then dropped onto the rocks until they splinter and crack open, allowing her access to the somewhat juicier interior. This is a learned behaviour, and it can take her seven years to master it.
