Bearded Scrub-Robin

Identification

Its length is 15–17 cm (5.9–6.7 in), and its weight is approximately 20–31 g (0.71–1.09 oz). The male and female are alike, with the female being slightly smaller. The crown and upperparts are mostly dark olive-brown. The tail is dark brown, with the outer feathers having white tips. The wing coverts are grey-brown with olive-brown edges. The flight feathers are dark brown, with a white patch. On the face, there are a white supercilium, a white crescent shape below the eye, a white moustachial line, and a black malar stripe. There are also black lines above the supercilia. The eyes are dark brown and the lores are black. The throat and upper breast are white. The breast and neck-sides are rufous-brown to rufous. The belly and undertail coverts are white. The beak is black, and the legs are pinkish-brown. The juvenile is paler brown, with black patterns on its crown and back, and its underparts are buff, with dark patterns. C. q. greenwayi has greyer upperparts, a duller rump, and a paler breast.

Taxonomy

This species was described as Thamnobia quadrivirgata by Reichenow in 1879. It was formerly placed in the genus Erythropygia. It forms a superspecies with the forest scrub robin, miombo scrub robin and brown scrub robin. These four species are sometimes placed in the genus Tychaedon. Two subspecies of C. quadrivirgata are recognized: C. q. greenwayi in the Zanzibar and Mafia Islands, and C. q. quadrivirgata in the rest of the range. The specific epithet quadrivirgata means "four-striped" in Latin. The species is so named because of four diagnostic stripes on its face.

Range and habitat

It is found in Botswana, Eswatini, Kenya, Malawi, Mozambique, Namibia, Somalia, South Africa, Tanzania, Zambia, and Zimbabwe, with a distribution size estimated at 5,390,000 km2 (2,080,000 sq mi). It is mostly found at elevations of below about 1,000 m (3,300 ft). 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.
