Red-billed oxpeckers (Buphagus erythrorhynchus) on a Buffalo

The red-billed oxpecker is a passerine bird in the starling and myna family Sturnidae; some ornithologists regard the oxpeckers to be in a family by themselves, the Buphagidae. It is native to the savannah of sub-Saharan Africa, from the Central African Republic east to South Sudan and south to northern and eastern South Africa. Its range overlaps that of the less widespread yellow-billed oxpecker.
