Southern ground-Hornbill (Bromvoël)

Scientific name: Bucorvus leadbeateri


The southern ground hornbill is characterized by black coloration and vivid red patches of bare skin on the face and throat (yellow in juvenile birds), which are generally believed to keep dust out of the birds eyes while they forage during the dry season. The white tips of the wings (primary feathers) seen in flight are another diagnostic characteristic. The beak is black and straight and presents a casque, more developed in males. Female southern ground hornbills are smaller and have violet-blue skin on their throats. Juveniles to six years old lack the prominent red pouch, but have a duller patch of grey in its place.
The Southern ground-hornbill occurs from Kenya and the DRC to southern Africa, where it is widespread but fairly scarce in Botswana, Zimbabwe, Mozambique, KwaZulu-Natal, Eastern Cape, Limpopo Province and northern Namibia. It generally prefers grassland and savanna woodland habitats, ranging from montane grassland to extensive, tall stands of Zambezi teak (Baikiaea plurijaga), Mopane (Colospermum mopane) and Musasa (Brachystegia spiciformis) woodlands with sparse understorey.
Mainly eats animals, such as insects, frogs, mongooses and bird nestlings. It forages in groups, so that when one bird locates a prey item it can signal the rest of the flock with a low bark.  It often finds prey by digging, especially in dung heaps, and it may snatch food from birds of prey.
