Description

The Karoo chat is 16–18 cm long and weighs around 32 gm. Its upperparts are grey, but it has a rufous patch behind the eye, and the tail is black with white outer feathers. Its underparts are white, the short straight bill, legs and feet are black and the eye is dark. The sexes are similar, but the juvenile is spotted with buff and has scaly underparts.. This species is paler than the similar grey form of the female mountain wheatear, from which it also differs in having a grey (not white) rump and completely white outer tail feathers. Its larger size and all-white outer tail feathers prevent confusion with the tractrac or

Conservation status

This common species has a large range, with an estimated extent of 1,100,000 km². The population size is believed to be large, and the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
