Pretty little gray waxbill with a black tail and a red rump which is conspicuous in flight. The male has red and black under the tail, while the female is much paler and grayer below. Both sexes have pink in the bill. Found in arid woodland and savanna, including mopane woodland. Shy and inconspicuous; usually in small flocks. Calls include rising whistles. Very similar to Black-tailed Waxbill, but prefers drier habitat and is paler gray, with pink on the bill.
