Distribution

It is found in Botswana, Kenya, Malawi, Mozambique, Namibia, Somalia, South Africa, Swaziland, Tanzania, Zambia, and Zimbabwe, with a distribution size estimated at 5,390,000 km2. It is mostly found at elevations of below about 1,000 m. Its occurs in sand forests, riverine woodland, scrubs, evergreen forests, and sometimes gardens and reedbeds, but usually not in damp areas. In the 1950s, deforestation near Hluhluwe and False Bay destroyed some of its habitat, but in some areas, its range may have expanded. In the 1940s, tsetse deterrent was sprayed in Hluhluwe-Umfolozi Game Reserve, and bearded scrub robins disappeared, but they recolonized the area by 1975. The species has also expanded into Matobo National Park and Richards Bay.

Status

The population size of this species is not known. It has a large range, appears to have a stable population trend and does not appear to have substantial threats, so the IUCN Red List has listed the species as least concern.

Behavior

The bearded scrub robin is usually found in pairs or small groups. Its calls include "chuck", "chrrrt", "chek-chek-kwezzzzzzz" and "seeeep". Its song is a series of melodious whistles and may mimic some other species of birds. It forages on the ground, eating ants, termites, beetles and other insects. It often sandbathes. The mating system is monogamous. It is territorial, defending territories that can reach 1 hectare in area. The breeding season ranges from December to February in eastern Africa, September to January in Malawi, Zambia and Zimbabwe, and September to December in South Africa. The nest is made of plants, lichen and hair. The clutch size is two to three eggs. The eggs may be white, pale green or bluish, and have many spots. The female incubates the eggs.
