The black harrier (Circus maurus) is a medium-sized African harrier whose range extends from South Africa to Botswana and Namibia. It has a wingspan of 105–115 cm (41–45 in) and a body length of 44–50 cm (17–20 in). When perched, this bird appears all black. However, in flight a white rump and flight feathers become visible. Its morphology is comparable to that of other harriers, with a slim body, narrow wings and a long tail. Male and female plumages are similar. Juveniles have buff under-parts and heavily spotted breasts.
