The karoo korhaan (Heterotetrax vigorsii), also known as karoo bustard, is a species of bird in the bustard family, Otididae, from Southern Africa. There are two subspecies, the nominate race, from south-eastern South Africa, and H. v. namaqua (Roberts, 1932), from north-western South Africa and southern Namibia. [3]
The karoo korhaan lives in a range of arid habitats associated with the karoo and other arid scrubland habitats found in western South Africa and Namibia. It is also found in slightly denser scrubland, preferring habitat with cover ranging from 10 to 50 cm (3.9–19.7 in) off the ground. A small population can also be found in karoo-like fynbos habitat in the Western Cape province. [3]
The karoo korhaan is a small bustard, 60 cm (24 in). Males are larger and heavier, weighing 1,600 g (56 oz) compared to the female's 1,350 g (48 oz). The head, neck and breast of the nominate subspecies is grey-brown, with a black chin and throat edged in white. The belly is pinkish white, and the wings are brown. The female is similar to the male but has less black on the throat. The neck and breast of the subspecies E. v. namaqua is greyer compared to the nominate subspecies. [3]
Karoo korhaans are omnivorous, but plant material is dominant in their diet. Flowers, fruit, leaves and corms all being taken. In particular, flowers from Asteraceae, Brassicaceae and Mesembryanthemaceae are all seasonally important. [3]

The kori bustard is the largest flying bird native to Africa. It is a member of the bustard family, which all belong to the order Otidiformes and are restricted in distribution to the Old World. It is one of the four species in the large-bodied genus Ardeotis. In fact, the male kori bustard may be the heaviest living animal capable of flight.
Tankwa Karoo National Park is a national park in South Africa. The park lies about 70 km due west of Sutherland near the border of the Northern Cape and Western Cape, in one of the most arid regions of South Africa, with areas receiving less than 100 mm of average annual precipitation, moisture-bearing clouds from the Atlantic Ocean being largely stopped by the Cederberg mountains. Other low areas receive little more, as the Roodewerf station with 180 mm of mean annual rainfall. In the hottest areas of the park, the mean maximum temperature in January is 38.9 °C, and in July the mean minimum temperature ranges from about 5 to 7 °C. Before this Park's proclamation, the only protected area of Succulent Karoo was the 2 square kilometre patch of the Gamkaberg Nature Reserve. Succulent Karoo has, together with the Cape Floral Kingdom, been declared a Biodiversity Hotspot by Conservation International.
The bokmakierie is a bushshrike. This family of passerine birds is closely related to the true shrikes in the family Laniidae, and was once included in that group. This species is endemic to southern Africa, mainly in South Africa and Namibia, with an isolated population in the mountains of eastern Zimbabwe and western Mozambique.

The common names for this species refer to the English explorer, Major Dixon Denham, and the English naturalist Edward Smith-Stanley, 13th Earl of Derby.

The southern black korhaan, also known as the black bustard, is a species of bird in the bustard family, Otididae. This small bustard is found in southwestern South Africa, from Namaqualand, south to Cape Town and east to Makhanda.

The little brown bustard is a species of bird in the family Otididae. Found in Ethiopia and Somalia, its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical dry lowland grassland. As indicated by its name, this bustard is the world's smallest at 45 cm (18 in) and 600 grams (1.3 lb). It is threatened by habitat destruction.

The head and neck are grey, with black stripes down the throat, through the eye, and on the sides of the neck, and white cheeks. The body is sandy brown above, and white below. The legs are sandy yellow-brown. Rüppell's korhaan received its name to recognize Wilhelm Rüppell, a German explorer, collector and naturalist. It is native to southwestern Africa in Angola and Namibia, according to Collar, N. J. - "The bustards and their conservation." Bustard in Decline, Jaipur (1982): 244–255. It is one of 13 native bird species found in the western part of Namibia. Normally they inhabit areas with low rainfall such as deserts, plains, and savannahs, where their exceptionally well developed senses play a major role in their survival and safety. They are most likely to be found in the Namibrand Nature Reserve, at Mirabib and Ganab in the Namib-Naukluft Park, at Bloedkoppie, and in the Spitzkoppe surroundings.
