Eastern northern Cape, extreme western Orange Free State, bush- veld regions of the Transvaal highveld (east as far as Leydsdorp), Rhodesia in the dry west and locally over the midlands to Salisbury, Marandellas, Umvuma and Fort Victoria, southwestern Zambia, southwestern, western and northern Botswana (generally north of a line Ghanzi-Damara Pan- Molepolole), and Caprivi and adjacent southeastern Angola. Remarks. The birds of the Makgadikgadi Salt Pan complex of Botswana and adjacent areas tend to become greyer through insolation and wear than in the case of populations of the same taxon occurring to the east (in Rhodesia i and the Transvaal).
