Bearded vulture

The lammergeyer, or bearded vulture, is a massive bone-eating bird of prey found in mountainous regions. Unlike other vultures, it specializes in cracking open bones to feed on marrow, making its diet one of the strangest in the animal kingdom.

• It gets most of its nutrition from bones, which make up 70–90% of its diet.
• It is the only known vertebrate that primarily eats bones.
• This bird belongs to its own unique genus, Gypaetus, with no close relatives.
