The boulder chat is a large chat, 25 cm in length, with brownish-black plumage and white tips to the outer tail feathers. In flight, a row of small white spots can be seen on the edge of the primary and secondary coverts. Females are similar to males but have a slightly duller plumage.

There are distinct populations in the far west of Botswana and southern Zimbabwe; north eastern Zimbabwe, extending into western Mozambique; and a third population in eastern Zambia extending up the Luangwa valley into Malawi.
