About the Black Harrier

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 becomes visible. Its morphology is comparable to that of other harriers, with narrow wings, a slim body, and a long tail. Male and female plumages are similar, while juveniles have buff underparts and heavily spotted breasts.

In South Africa, the distribution of the black harrier is distinctly polarised in both the Western and Southern coastal plains. Nests are concentrated either along the coastal strip or inland in a more montane habitat. Nests are generally absent from transformed and cultivated lands. There is, however, some evidence from sightings and prey remains that the black harriers do forage in these environments even if they do not breed there.

Black harriers are migratory birds and their annual movements cover the southern half of the land surface of South Africa (including Lesotho) however, there is great individual variability. The... Wikipedia →
