The northern black korhaan (Afrotis afraoides), also known as the white-quilled bustard, [3] is a species of bird in the bustard family, Otididae. It is widely distributed across Southern Africa. Its habitat is primarily open grassland and scrub.
The northern black korhaan was first described in 1831 by the Scottish surgeon, explorer and zoologist Andrew Smith, who gave it the specific name "afraoides". He placed it in the genus Eupodotis , where it was one of two species, the other being the southern black korhaan (Eupodotis afra). In 1993, Dowsett and Forbes-Watson listed it as a sub-species of E. afra, while Sibley and Monroe (1990 and 1993) retained it as a separate species. Then in 2014, del Hoyo and Collar transferred both species to the genus Afrotis . [1]
The male's plumage has regularly-arranged black and white barring on the back and wings, the head, neck and underparts being black. The female has the head, neck, breast and upper parts barred or chequered in black and buff, the belly being black. The primary feathers are largely white, which distinguishes this species from the southern black korhaan where they are black. Both the female and the male have red beaks and bright yellow legs. [4]
The northern black korhaan is found in Namibia, Botswana, Lesotho and northern South Africa. [3] Its habitat is grassland, with vegetation up to a metre high, grassy dunes, semi-arid scrubland and open veldt. [4]
The northern black korhaan is a mainly ground-dwelling bird, but it does sometimes burst into flight when disturbed, the male emitting a loud, raucous "kraark, kraark" call. The male will often run away from an intruder with head and neck extended, before freezing, becoming surprisingly difficult to observe in the process. The female is less conspicuous and is seldom seen. The birds forage while walking along, feeding on and chasing after insects such as termites, ants, grasshoppers and beetles, as well as spiders, ticks and seeds. Breeding takes place at any time of year. The male has a courtship display involving dipping flights, flaring white feathers and the ritual chasing of other birds. He displays to several females but is territorial, and drives away other males. The nest is a scrape on the ground containing one or two eggs. [5]
The International Union for Conservation of Nature has assessed the conservation status of this species as being of "least concern". This is because it is a common species with a wide range, no particular threats have been identified, and the population seems stable. [1]
Bustards, including floricans and korhaans, are large, terrestrial birds living mainly in dry grassland areas and on the steppes of the Old World. They range in length from 40 to 150 cm. They make up the family Otididae. Bustards are omnivorous and opportunistic, eating leaves, buds, seeds, fruit, small vertebrates, and invertebrates. There are 26 species currently recognised.
The little bustard is a bird in the bustard family, the only member of the genus Tetrax. The genus name is from Ancient Greek and refers to a gamebird mentioned by Aristophanes and others.
The ring-necked dove, also known as the Cape turtle dove or half-collared dove, is a widespread and often abundant dove species in East and southern Africa. It is a mostly sedentary bird, found in a variety of open habitats. Within range, its penetrating and rhythmic, three-syllabled crooning is a familiar sound at any time of the year. Its name is derived from the semi-collar of black feathers on the lower nape, a feature shared with a number of Streptopelia species. Like all doves, they depend on surface water. They congregate in large flocks at waterholes in dry regions to drink and bathe.
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.
The lesser florican, also known as the likh or kharmore, is the smallest in the bustard family and the only member of the genus Sypheotides. It is endemic to the Indian Subcontinent where it is found in tall grasslands and is best known for the leaping breeding displays made by the males during the monsoon season. The male has a contrasting black and white breeding plumage and distinctive elongated head feathers that extend behind the neck. These bustards are found mainly in northwestern and central India during the summer but are found more widely distributed across India in winter. The species is highly endangered and has been extirpated in some parts of its range such as Pakistan. It is threatened both by hunting and habitat degradation. The only similar species is the Bengal florican which is larger and lacks the white throat, collar and elongated plumes.
The Australian bustard is a large ground dwelling bird which is common in grassland, woodland and open agricultural country across northern Australia and southern New Guinea. It stands at about one metre high, and its wingspan is around twice that length. The species is nomadic, flying to areas when food becomes plentiful, and capable of travelling long distances. They were once widespread and common to the open plains of Australia, but became rare in regions that were populated by Europeans during the colonisation of Australia. The bustard is omnivorous, mostly consuming the fruit or seed of plants, but also eating invertebrates such crickets, grasshoppers, smaller mammals, birds and reptiles.
Denham's bustard, Stanley bustard or Stanley's bustard is a large bird in the bustard family. It breeds in much of Sub-Saharan Africa. It is a species of open ground, including agricultural land, grassland, flood-plains and burnt fynbos. It is resident, but some inland populations move to lower altitudes in winter. 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. It prefers semi-arid habitats such as grasslands, shrublands and savannas where it can easily prey on ground-dwelling arthropods and eat seeds. It reproduces yearly in the spring and will lay about one or two eggs per breeding season.
Eupodotis is a genus of bird in the bustard family Otididae. It contains the five species, all restricted to Africa. Species in the genera Afrotis and Lophotis are sometimes included in this genus; however some authorities separate the Karoo korhaan, Rüpell's Korhaan and little brown bustard as a separate genus Heterotetrax.
The blue korhaan or blue bustard is a species of bird in the family Otididae which is native to South Africa. Its call is a series of frog-like croaks, usually uttered in flight. Its natural habitat is plateau grassland, dry shrubland, arable land and pastureland. Its preferred habitat is one with short grassland and flat topography.
The buff-crested bustard is a medium-sized bird of East Africa belonging to the family Otididae. The populations are stable and the species is of least concern.
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 black-bellied bustard, also known as the black-bellied korhaan, is an African ground-dwelling bird in the bustard family.
Rüppell's Korhaan, also known as Rüppell's bustard, is a species of bird in the family Otididae. The species is a small bustard, only 60 cm long. 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, Collar, N. J. "The bustards and their conservation." Bustard in Decline, Jaipur (1982): 244–255. It is one of Namibia's 13 native birds found in the western part of the country. On overage they inhabit areas with low rainfall such as deserts, plains, and savannahs. Where their exceptionally senses play a major role in their security. It is most likely found in Namibrand nature reserve, Mirabib, Ganab in the Namib-Naukluft Park, Bloedkoppie, and in the Spitzkoppe surroundings.
The red-crested korhaan or red-crested bustard is a species of bird in the family Otididae. It is found in Angola, Botswana, Mozambique, Namibia, South Africa, Swaziland, Zambia, and Zimbabwe.
Savile's bustard is a species of bird in the family Otididae. Otididae are an Old-World and understudied family of birds mostly found in Afro-Tropical regions. It is found in Burkina Faso, Cameroon, Chad, Ivory Coast, Gambia, Mali, Mauritania, Niger, Nigeria, Senegal, and Sudan.
The white-bellied bustard or white-bellied korhaan is an African species of bustard. It is widespread in sub-Saharan Africa in grassland and open woodland habitats.
The karoo korhaan, 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. There are two subspecies, the nominate race, from south-eastern South Africa, and E. v. namaqua, from north-eastern South Africa and southern Namibia.
The black korhaans are two closely related species of bustard:
