Distribution and habitat
Although it has an isolated population in Angola, it mainly
occurs in southern Africa from Zimbabwe, eastern Botswana and Mozambique to
South Africa, excluding most of the Northern Cape, Free State and North-West
Province. It generally prefers woodland and plains and hillsides, such as
Acacia, broad-leaved and dry riverine woodland, also occupy forest edges,
grassy protea scrub and the border between natural vegetation and cultivated
land and gardens.

Breeding
- Monogamous, solitary or loosely colonial nester, as it sometimes forms
small groups with little if any territoriality.
- The nest is probably built solely by the female, consisting of a cup of
dead leaves, grass, bark, twiglets, dead seedheads, textiles and paper,
lined with fluffy seeds or other plant down. It is typically placed in the
upright or horizontal fork of a bush or tree, among Bitter aloe (Aloe
ferox) leaves or in a cluster of pine cones.
- Egg-laying season is from September-March.
- It lays 2-4 eggs, which are incubated solely by the female for about
12-15 days.
- The chicks are brooded by their mother for the first 5 days or so of
their lives, and are fed by the female with food provided by the male. They
leave the nest at about 17 days old, but they remain dependent on their
parents for food for some time.
Threats
Not threatened.
