Introduction
The Northern Black Korhaan, also called the White-quilled Bustard, is a ground-dwelling member of the bustard family, Otididae. Its accepted scientific name is Afrotis afraoides. It occurs mainly in open, dry grasslands, savannas and semi-arid country across parts of southern Africa. Males are especially conspicuous during their territorial display, while females are more cryptically coloured.
Physical Description
The Northern Black Korhaan is a medium-sized bustard, generally about 50–55 centimetres long. It has a sturdy body, long legs and a relatively short, broad bill adapted to ground feeding.
The sexes are strongly different in appearance:
- The adult male has predominantly black underparts and head markings, contrasting with white areas on the face, throat, neck and wings. White flight feathers or wing panels are particularly noticeable when the bird flies.
- The female is smaller-looking and mainly brown, buff and finely patterned, providing camouflage among grass and scrub.
- Juveniles resemble females but are usually duller and less sharply marked.
The contrast between the male’s black-and-white plumage and the female’s cryptic colouring is one of the most useful features for field identification. The species is closely related to the Southern Black Korhaan, but the Northern Black Korhaan is distinguished by its range, habitat associations and the conspicuous white in the wing visible in flight.
Range and Habitat
The Northern Black Korhaan is a resident species of southern Africa. Its range includes parts of Namibia, Botswana, South Africa and Lesotho, with important populations on the South African plateau and in the Kalahari region. It is not regarded as a long-distance migrant, although local movements may occur in response to rainfall, food availability and changing habitat conditions.
It favours open, relatively flat country, including dry grassland, grassy savanna, semi-desert scrub, sandy areas and lightly wooded or shrub-dotted plains. It can tolerate some grazing and disturbed land, but intensive cultivation and the loss of natural grassland can reduce suitable habitat. The species is most often encountered on the ground, where its plumage helps it blend into dry vegetation.
Where to See This Species
Kgalagadi Transfrontier Park, Northern Cape and Botswana
SANParks records the Northern Black Korhaan throughout the duneveld of Kgalagadi Transfrontier Park. Look along the park’s open sandy roads and dry grassland, particularly where the vegetation is low enough to provide clear views. The species may be seen while driving, although it can remain inconspicuous until disturbed or calling.
Nearby accommodation: Twee Rivieren and other park camps provide practical access to campsites, cabins and self-catering accommodation, with additional guest houses and lodges available in nearby Kgalagadi gateway settlements.
Mokala National Park, Northern Cape, South Africa
The SANParks bird checklist for Mokala National Park includes the Northern Black Korhaan. The park’s open grassland, dry savanna and gently wooded plains provide suitable habitat for this ground-dwelling species. Early morning and late afternoon are sensible times to search, when birds are more active and temperatures are lower.
Nearby accommodation: Kimberley is the nearest major town and offers hotels, guest houses, lodges and self-catering accommodation. The park also provides accommodation within the reserve.
Central Karoo around Nieu-Bethesda, Eastern Cape, South Africa
BirdLife South Africa’s birding information for the wider Nieu-Bethesda area reports Northern Black Korhaans as prevalent in grassland and karroid scrub. The species can be searched for along suitable public roads and birding routes around the town, while respecting land access restrictions because much of the surrounding area is privately owned.
Nearby accommodation: Nieu-Bethesda provides guest houses, cottages and self-catering accommodation, with additional lodges and farm stays available in the wider Karoo region.
Behaviour and Diet
The Northern Black Korhaan is mainly diurnal and spends much of its time walking through open vegetation in search of food. It is generally encountered singly or in pairs, although several birds may occur in the same area where suitable habitat and food are available.
Its diet is mixed but includes a substantial animal component. Insects, including beetles and termites, form important food items, while seeds, flowers, leaves and other plant material are also taken. The balance of animal and plant food varies with season and local availability.
Males defend territories and perform conspicuous courtship displays. These may include rapid or vertical flights, wing movements and loud calls, often carried out over or near a territory. Breeding is associated with favourable conditions and may occur during different periods across the species’ range, particularly after rainfall has improved food availability.
The nest is a shallow scrape on the ground, usually placed in grassland or low vegetation. The female undertakes incubation and cares for the young. The chicks are precocial, leaving the nest soon after hatching and following the female while they develop their foraging skills.
Identification Tips
- Look for a medium-sized bustard walking through open grassland, dry savanna or sandy country.
- Adult males show a striking black-and-white pattern, with conspicuous white in the wing during flight.
- Females are mainly buff-brown and finely patterned, making them much harder to detect than males.
- The species is usually identified by habitat and range as well as plumage. In southern Africa, compare it carefully with the Southern Black Korhaan, which occupies more southerly habitats and lacks the Northern Black Korhaan’s conspicuous white primaries.
- A bird standing motionless in dry grass may be difficult to see. Scanning slowly along road verges and open plains is often more effective than looking only for moving birds.
Conservation Status
The Northern Black Korhaan is assessed as Least Concern on the global IUCN Red List. A precise global population estimate is not available in the sources used here, and the species’ overall population trend should therefore be interpreted cautiously.
The main potential pressures are the conversion and intensification of open grassland for agriculture, infrastructure development and other land uses. Changes in grazing regimes and the loss of natural vegetation may also affect local populations. Protected areas such as Kgalagadi Transfrontier Park and Mokala National Park help conserve important habitat, while maintaining connected open grassland and responsible land management remains important outside reserves.
Frequently Asked Questions
Where does the Northern Black Korhaan live?
It occurs in parts of Namibia, Botswana, South Africa and Lesotho. It prefers open grassland, dry savanna, semi-arid scrub, sandy plains and lightly wooded country.
Is the Northern Black Korhaan migratory?
It is generally regarded as a resident species rather than a long-distance migrant. Local movements may occur when rainfall, food supplies or habitat conditions change.
What does the Northern Black Korhaan eat?
Its diet includes insects such as beetles and termites, together with seeds, flowers, leaves and other plant material. Insects may be especially important when adults are feeding young.
How can the male be distinguished from the female?
The male has bold black-and-white plumage and conspicuous white in the wing. The female is smaller-looking and mainly buff-brown, with finely patterned upperparts that provide camouflage.
Where is the best place to see a Northern Black Korhaan?
Kgalagadi Transfrontier Park is one of the most reliable publicly accessible places to look for the species. It is also recorded at Mokala National Park and in suitable grassland and karroid scrub around Nieu-Bethesda.
What is the conservation status of the Northern Black Korhaan?
The species is currently assessed as Least Concern globally. Nevertheless, the loss and intensification of open grassland can affect local populations and should be managed carefully.
