The Black Hawk-Eagle is 58–70 cm (23–28 in) long and weighs about 900-1,300 grams (2-2.9 lbs). 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.
