The black eagle is a species of the genus Accipitridae. It often inhabits woodlands near grasslands and wetlands, and often hunts in flight or on the ground, preying on animals such as hyraxes, guinea fowls, monkeys, and hares. It builds nests on alpine rocks or trees, using branches and bark to build a dish. Each nest lays 1-3 eggs, usually 2 eggs. The eggs are pale white and have an incubation period of 42-44 days.
The black eagle is larger and has fewer stripes than the tawny eagle, and shares more or less the same range with the tawny eagle in East Africa. The plumage of the young birds is a mixture of red, brown, and black. Black eagles are resident birds and will hunt cooperatively in pairs, although some very localized movements may occur within the network of hills that make up most of their habitat. They hunt in flight or on the ground. The species inhabits remote, mountainous, rocky areas, as well as savannas and semi-deserts, anywhere rock hyraxes occur in large numbers. Throughout most of its range, its abundance is highly correlated with the density of hyraxes.
More than 60% of the black eagle's prey is hyraxes, but it will occasionally take other mammals, birds, tortoises, and rarely reptiles. Like all predators with nearly exclusive or equally undiverse diets, once hyrax resources are depleted, their survival will be threatened by years of poor reproduction.
Despite the risks posed by its diverse diet, the black eagle is not an endangered species. It is relatively common in its suitable habitat, especially in South Africa. The species population is estimated to be in the tens of thousands. Trend proof: As of 2016, the species is considered stable with no evidence of decline or major threats.
