The Lammergeier lives on a diet of bone marrow and rubs soil on its own feathers to appear more intimidating. It is a pretty badass bird. These giant birds can grow up to 4 feet tall. They have a wingspan between 7 and 9 feet and usually weigh around 10 to 15 pounds. In captivity, lammergeiers can live to the ripe old age of 45.
