The Kalahari Scrub Robin inhabits arid and semi-arid, open habitats with scattered trees and bushes, particularly thorn-savannas, where it hunts on the ground for insects and spiders. Adults grow to a length of about 15 cm and weigh around 20g.
The breeding season for Kalahari Scrub Robins stretch from mid-winter to the end of summer, peaking around October and November. Their untidy nests are built of plant material and hair and placed low in shrubs. Pairs are monogamous and territorial, the male defending the nesting site with the female being solely responsible for incubating the clutch of 2-4 eggs for a period of 2 weeks. The chicks leave the nest about 2 weeks after hatching.
Apart from South Africa (Northern Cape, North West, Free State and Limpopo), the Kalahari Scrub Robin is found in Botswana, Namibia, Zimbabwe and marginally into Angola. The IUCN lists it as being of least concern.
