Introduction
The Southern Black Korhaan (Afrotis afra) is a medium-sized bustard endemic to South Africa. It occurs mainly in the open fynbos, renosterveld, strandveld and Karoo habitats of the Western, Northern and Eastern Cape provinces. The species is known for the contrasting plumage of the adult male, its ground-dwelling habits and its loud breeding calls.
Physical Description
The Southern Black Korhaan measures approximately 50–53 cm in length. Adult males are predominantly black, with a contrasting white patch on the ear coverts, a white collar across the mantle and white wing coverts that form a conspicuous pale edge when the wing is folded. The crown is brown, while the bill is reddish with a grey tip and a pale sub-terminal band. The legs are bright yellow.
Females are smaller and more cryptically coloured. They have buff-brown heads, necks and breasts, with black largely confined to the belly. Juveniles resemble females but usually show paler edges on the dorsal and flight feathers.
Range and Habitat
The Southern Black Korhaan is endemic to South Africa. Its range extends through parts of the Western, Northern and Eastern Cape provinces, from the Namaqualand region southwards through the Cape lowlands and eastwards towards the Albany area.
It is associated with open, relatively low vegetation in the Fynbos, Albany Thicket, Succulent Karoo and southern Nama Karoo biomes. Important habitats include renosterveld, strandveld, coastal fynbos, low shrubland, natural grassland and semi-arid scrub. The species generally prefers natural vegetation, although it may occur in cultivated areas where suitable habitat remains.
Habitat loss and fragmentation have reduced the extent and continuity of suitable habitat, particularly in areas affected by agriculture, urban expansion and other land transformation. The species is considered a resident rather than a long-distance migrant.
Where to See This Species
West Coast National Park, Western Cape, South Africa
SANParks lists the Southern Black Korhaan among the birds of West Coast National Park. The park’s strandveld, fynbos and open coastal vegetation provide suitable habitat, and the species is a realistic target in the park’s quieter terrestrial areas, especially where low vegetation gives clear views across open ground.
Nearby accommodation: Langebaan is the nearest practical town, with hotels, guest houses, self-catering accommodation and camping options, while the park also provides selected visitor accommodation.
Bontebok National Park, Western Cape, South Africa
The Southern Black Korhaan is recorded on the official bird checklist for Bontebok National Park. The park protects coastal renosterveld and other Cape vegetation near the Breede River, making open grassy and shrubby areas worth checking during a careful birding drive or walk.
Nearby accommodation: Swellendam is the nearest gateway town, with guest houses, hotels, self-catering accommodation, camping and park-based accommodation options.
Camdeboo National Park, Eastern Cape, South Africa
The official SANParks bird list for Camdeboo National Park includes the Southern Black Korhaan. The park’s open Karoo veld and low shrubland are appropriate habitat, particularly in areas away from dense development and where birds can forage on relatively open ground.
Nearby accommodation: Graaff-Reinet is the nearest practical settlement, offering guest houses, bed-and-breakfast accommodation, hotels, self-catering properties, camping and park-based accommodation.
Behaviour and Diet
Southern Black Korhaans spend much of their time on the ground, walking slowly through open vegetation while searching for food. Their diet includes insects, other invertebrates, small reptiles, seeds, green plant material and shoots. They pick food from the ground and use their keen eyesight to locate prey among grass and low shrubs.
Males are territorial during the breeding season and use loud, raucous calls and display flights to attract females and advertise their presence. The species is polygynous, with males pairing with more than one female. Breeding generally occurs from late winter through summer, with egg-laying recorded mainly from August to January and peaking around September and October.
The female usually lays one egg, with two recorded occasionally, in a shallow ground depression concealed by surrounding vegetation. She alone incubates the eggs and cares for the chicks. The young are precocial and can move and feed soon after hatching, remaining under the female’s protection while developing.
Identification Tips
- Look for a medium-sized, long-legged bustard walking through open low vegetation rather than perching in trees.
- An adult male is mostly black, with a white ear patch, a white mantle collar, bright yellow legs and a reddish bill.
- The female is much browner and more heavily camouflaged, with black mainly on the lower underparts.
- The pale edge formed by the white wing coverts is conspicuous when a male is seen in flight or turning sideways.
- The Southern Black Korhaan lacks the prominent white primaries associated with the Northern Black Korhaan (Afrotis afraoides), which is an important identification feature where the two species could be confused.
- Listen for the male’s loud, harsh call, particularly during the breeding season, and watch open ground carefully because the birds may remain still or walk unobtrusively through low vegetation.
Conservation Status
The Southern Black Korhaan is classified as Vulnerable. Its population has declined as natural habitat has been cleared, converted to agriculture or broken into smaller isolated patches. Habitat transformation can also reduce breeding cover and the availability of natural food resources.
Important conservation measures include protecting remaining renosterveld, strandveld, fynbos and Karoo habitats, maintaining connected areas of natural vegetation, improving habitat management on farms and limiting further fragmentation. The species’ global population has not been quantified reliably, so unsupported population estimates should be avoided.
Frequently Asked Questions
Where is the Southern Black Korhaan found?
It is endemic to South Africa and occurs mainly in the Western, Northern and Eastern Cape provinces, especially in open fynbos, renosterveld, strandveld and Karoo habitats.
What does the Southern Black Korhaan eat?
Its diet includes insects, other invertebrates, small reptiles, seeds and green plant material. It usually finds food while walking and foraging on the ground.
How can a male Southern Black Korhaan be identified?
The male is mostly black, with a white ear patch, a white collar across the mantle, bright yellow legs and a reddish bill. White wing coverts create a noticeable pale edge on the folded wing.
Is the Southern Black Korhaan migratory?
It is generally regarded as a resident species. Individuals may move locally in response to habitat conditions and food availability, but it is not known for long-distance migration.
When does the Southern Black Korhaan breed?
Breeding has been recorded mainly from August to January, with activity peaking around September and October. The female usually lays one egg and is responsible for incubation and chick care.
What is the main threat to the Southern Black Korhaan?
The principal threat is the loss and fragmentation of natural habitat through agricultural expansion, urban development and other land transformation.
