Southern Bald Ibis

About the Southern Bald Ibis

The southern bald ibis (Geronticus calvus) is a large bird found in open grassland or semi-desert in the mountains of southern Africa. Taxonomically, it is most closely related to its counterpart in the northern regions of Africa, the waldrapp (Geronticus eremita). As a species, it has a very restricted homerange, limited to the southern tips of South Africa in highland and mountainous regions.

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 two or three eggs which are incubated for 21 days before hatching. It is a large bird that feeds and roosts in substantial groups. It feeds on insects, small reptiles, rodents and small birds. They do little vocalizing other than occasional gobbling sounds.

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. The species is currently listed as near threatened on the IUCN Red List, however, it is in no immediate danger of extinction. Wikipedia →
