Identification

The southern tchagra is 17–21 cm in length. It has a brown crown and black eye stripes separated by a broad white
supercilium The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also ...

, but that species is larger, and the adult, as its name implies, has a black rather than brown crown. An identification pitfall is that juvenile black-crowned tchagra has a brown crown. It can be separated from southern tchagra by its larger size, relatively shorter bill and paler underparts. There are three fairly similar subspecies of southern tchagra. Nominate ''T. t. tchagra'' of the Western Cape has the darkest underparts and longest bill. ''T. t. caffrariae'' has paler underparts and the shortest bill, and ''T. t. natalensis'' of eastern South Africa and Eswatini has the palest underparts and a reddish-brown crown. The male southern tchagra has a descending whistling song, ''ttttrtr te te te teuuu'' given in its display flight or from a perch. The female responds with a trilled ''tzerrrrrrrr''.

s are laid. These are white, marked with grey and reddish-brown, and hatch after about 16 days, with another 14 days to fledging. This is a solitary territorial species, less conspicuously than true shrikes, especially when breeding. It forages on the ground for insects and other small prey.
