Bateleur Eagle

Bateleur Eagle (Helotarsus ecaudatus), sometimes called the Short-tailed Eagle, from the northeastern and southern parts of Africa. It is about two feet long, general colour on upper surface black, with greenish-metallic gloss, tail brownish red, and an ash-grey band on wings. The name bateleur, which is French, and means "a tumbler," was given to the bird by Le Vaillant from its habit of turning somersaults in the air.
