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
Karoo Group (i.e. the oldest layer of the Cape Supergroup). The valley floor is covered, in the main, by the next (younger) layer of the Supergroup, namely the much softer Bokkeveld shales. The dolerite of the Great Karoo did not penetrate these rocks, so Karoo Koppies are not seen in the Little Karoo. The Little Karoo contains two other geological features that give the landscape a special character. During the erosion of the African interior following the bulging of the continent during the massive lava outpourings that ended the Karoo sedimentation 180 million years ago, some of the eroded material was
