Distribution and habitat

Near endemic to southern Africa, occurring from eastern Botswana to Zimbabwe and northern Mozambique, marginally extending into Angola and Zambia. It mainly occupies well-wooded granite outcrops, batholiths and hills, where there are scattered granite boulders around the top and scree slopes at the base. If in area becomes to densely vegetated it often deserts the place permanently.

Colours range from dark blue (most common) through to yellow (least common).

Brood parasites

It has been recorded as host of the Red-chested cuckoo.

Food 

It mainly eats arthropods and small lizards, doing some of its foraging on the ground beneath boulders and rocks, occasionally in leaf litter. It may hawk insects aerially from a perch on a rock, and it also clumsily hovers next to trees, gleaning food from their leaves and branches.

Breeding

  • The nest is cup built of bark, leaves and twigs, set into a foundation of earth clods and lined with leaf petioles. It is typically placed underneath a boulder, in a cavity between two rocks or next to a log.
  • Egg-laying season is from September-January, peaking from October-November.
  • It lays 2-4 eggs, which are incubated for about 13-14 days.
  • The chicks leave the nest at about 16-20 days old, before they can fly, after which they hide under boulders until they fledge. They may still remain dependent on their parents until the following breeding season

Threats

Not threatened, although it deserts any areas which become infested with the alien Cherry-pie (Lantana camara), which may cause problems for it in the future.
