Distribution and habitat

Endemic to southern Africa, occurring in the highveld of South Africa surrounding and extending into Lesotho. It generally prefers flat or undulating ground in grassland and Nama Karoo.

Distribution of Blue korhaan in southern Africa, based on statistical smoothing of the records from first SA Bird Atlas Project (© Animal Demography unit, University of Cape Town; smoothing by Birgit Erni and Francesca Little). Colours range from dark blue (most common) through to yellow (least common). See here for the latest distribution from the SABAP2.

Predators and parasites

Food 

It mainly eats insects, lizards and plant matter, doing most of its foraging by walking along and pecking the ground, often in cultivated fields. The following food items have been recorded in its diet:

Breeding

  • Its breeding system is complex, as it can be either monogamous or polygamous, usually in trios with either two males or two females. However it may also breed cooperatively in groups of up to five, together raising a brood and defending the nest against predators.
  • The nest is a simple scrape in the ground, usually between grass tufts tall enough to conceal the incubating bird.

  • Egg-laying season is from September-February, peaking from October-November.
  • It lays 1-2, rarely 3 eggs, which are solely incubated by a single female or multiple females (depending on the size of the family group) for about 24-28 days.
  • The chicks are fed by both parents, leaving the nest soon after hatching to join the family group, who vigorously defend them by chasing away or distracting predators. The young take their first flight at about five weeks old.

Threats

Near-threatened globally and regionally, although its population is decreasing, probably due to habitat loss caused by cultivation, human settlement and afforestation.
