    The black sparrowhawk (Accipiter melanoleucus), sometimes known as the black goshawk or great sparrowhawk, is the largest African member of the genus Accipiter. It occurs mainly in forest and non-desert areas south of the Sahara, particularly where there are large trees suitable for nesting; favored habitat includes suburban and human-altered landscapes. It preys predominantly on birds of moderate size, such as pigeons and doves, in suburban areas.
    Typically, both sexes of the black sparrowhawk have a predominantly black plumage with a white throat, breast and belly. These white-breasted individuals are known as "white morphs" which are in the majority over most of the birds' range. The "black morph" variety is generally rare, except along the coastal regions of South Africa, including the Cape Peninsula where they constitute 80% of the population. These "black morphs", when seen perched, can be black all over, but more commonly have a few white spots on the breast or a white throat of variable size. In flight both morphs show white and black barring on the underside of the wings and tail. The black morphs are not melanistic, as commonly alleged, as their plumage is not completely black, nor are they black as chicks or juveniles. There is no noticeable difference between the plumage of mature females and males, which can only be distinguished by size. The tails are cross-barred with about three or four paler stripes, and the undersides of the wings with perhaps four or five. The legs are yellow, with large feet and talons.
