This bird, as the name suggests, has a dark black feathering with varying patterns on each of its wings and body, and a speckled white colouring in places.It has barred wings, slightly elliptical in shape, and tail which is long and narrow and is rarely fanned. The four, grey hued "bars" seen on the tail quills 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. ["Birds of Venezuela" by Steve Hilty.Princeton University Press, 2003] While in flight, the bird's tail is typically kept closed.
Diet
Light and relatively small when compared to other members of its
genus , the main foods consumed by this bird includeopossum s andmonkey s, as well as, occasionally, small bats and other birds. Its popular name in Brazil is "Gavião-pega-macaco", wich means "monkey-catching hawk". These other birds can often be quite large, such astoucans , andchachalaca s. The dietary habits of the Black Hawk-Eagle, however, remain mostly unknown, with very few recordings of the bird eating.Breeding
Similar to knowledge of its diet, very little is known about the Black Hawk-Eagle's breeding behaviour other than some details relating to its
nest : comprised of sticks and possibly other materials, the nest is around one metre and a half in total diameter and is usually constructed in tall trees, often around fifteen metres high. The variety of tree chosen probably varies greatly, but they have been observed chiefly inpine tree s.Notes
