It is found in Angola, Botswana, Ethiopia, Kenya, Mozambique, Namibia, Rwanda, Somalia, South Africa, South Sudan, Swaziland, Tanzania, Uganda, Zambia, and Zimbabwe. Its natural habitat is the dry savanna.〔 ==Description== The body length of approximately 24 cm and the weight of 65 g place rank this as one of the largest of the Ploceidae (weaver birds). Visually the sexes are not greatly differentiated from one another. The red-billed buffalo weaver is differentiated from the white-billed buffalo weaver (''Bubalornis albirostris'') by the color of its bill. The feathers of the male are dark chocolate brown in color. The front wing edges and the wing tips are flecked with white. His bill is a shade of red. The eyes are brown and the feet are reddish brown. The female's body is also colored dark chocolate brown, without the white flecks on the wings. However, her chin and throat feathers include broad white colored hems. Her eyes are dark brown and her legs light brown. Adolescent birds are a lighter shade of brown.〔 Fry et al., p. 52 〕
