The Southern Bald Ibis (Geronticus calvus) is a large bird found in open grassland or semi-desert in the mountains of southern Africa.
This large, glossy, blue-black ibis has an unfeathered red face and head, and a long, decurved red bill. It breeds colonially on and amongst rocks and on cliffs, laying 2-3 eggs which are incubated for 21 days before hatching. It feeds on insects, small reptiles, rodents and small birds.
The ibises are gregarious long-legged wading birds with long down-curved bills; they form one subfamily of the Threskiornithidae, the other subfamily being the spoonbills. The two Geronticus species differ from other ibises in that they have unfeathered faces and heads, breed on cliffs rather than in trees, and prefer arid habitats to the wetlands used by their relatives.
