White-headed black-chat
Arnot's chat (Myrmecocichla arnotti ), also known as the white-headed black-chat, is a species of bird in the chat and flycatcher family Muscicapidae. The species is found in southern Africa from Rwanda and Angola to South Africa.
Arnot's chat ranges in size from 16 to 18 cm (6.3–7.1 in) and weighs around 35 g (1.2 oz). The plumage of the adults is sexually dimorphic; the male of the nominate race is overall black with a white crown and a white patch on the wing coverts. The female is similar but with a black crown and a white (tipped with black) throat and neck. The bill and legs are black. Juvenile birds are like the adults but with white feather tips on the crown or throat instead of fuller white. The male of the race harterti has less extensive white on the wings and a mostly black head with a small area of white on the forehead and above the eye; the white throat of the female is also less extensive than on the nominate.
Arnot's chat is most commonly found in healthy stands of miombo and mopane woodland. It also occurs at lower densities in other kinds of open woodland with little herbaceous cover, and very rarely near buildings. It generally occurs from sea level to 1,500 m (4,900 ft). The species is generally not migratory, but is presumed to undertake some localized wandering.
