Distribution and habitat

Endemic to southern Africa, occurring from southern Namibia to the Northern, Western and Eastern Cape. It generally prefers dwarf arid shrubland of the Nama Karoo and succulent Karoo, especially with stony ground, while in the Western Cape it also occurs in cultivated land.

Distribution of Karoo 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

Movements and migrations

Resident and sedentary.

Food 

Mainly eats invertebrates, reptiles and plant matter, doing most of its foraging by walking along the ground while plucking up food items. The following food items have been recorded in its diet:

Breeding

  • Monogamous, often breeding in family groups with a breeding pair and other helpers, who help to defend the territory.
  • The nest is a shallow scrape in the scrape in the ground, usually among scattered shrubs and rocks.
  • Egg-laying season is from June-February, peaking from December-January.
  • It lays a single egg, which is incubated solely by the female, who sometimes temporarily leaves the nest to go foraging with the male.
  • Little is known about the development and care of the chicks, other then that they leave the nest soon after hatching.

Threats

Not threatened, although vulnerable to farming activities on the Agulhas Plain, Western Cape, which can lead to the death of chicks and eggs.
