Karoo korhaan Karoo korhaan The karoo korhaan ("Eupodotis vigorsii"), also known as karoo bustard, is a species of bird in the bustard family, Otididae, from Southern Africa. The species is sometimes placed in the genus "Heterotetrax". It is the sister-species to Rüppell's korhaan, and the two species are sometimes considered conspecific (the same species). There are two subspecies, the nominate race, from south-eastern South Africa, and "E. v. namaqua" (Roberts, 1932), from north-eastern South Africa and southern Namibia. The karoo korhaan lives in a range of arid habitats associated with the karoo and other arid scrubland habitats found in eastern South Africa

An exception is the thriving ostrich-farming industry in the Little Karoo, which is heavily dependent on supplementary feeding with lucerne. The difference between the Succulent Karoo biome and the Nama Karoo biome is that the former receives the little rain that falls as cyclonic rainfall in winter, which has less erosive power than the infrequent but violent summer thunderstorms of the Nama Karoo. Frost is also less common in the Succulent Karoo biome than in the Nama
