Description
The black hawk-eagle is 58–70 cm (23–28 in) long and weighs about 900–1,300 grams (2-2.9 lbs). It has black plumage with varying patterns on its wings and body, and white speckling in places. It has barred wings, slightly elliptical in shape, and a long, narrow tail which is rarely fanned. The four grey bars on the tail are distinctive to the black hawk-eagle, as is the white line seen slightly above the bird's eye. While flying, the broadness and shortness of the wings become apparent. While in flight, the bird's tail is typically kept closed.
