The yellow-billed oxpecker (Buphagus africanus) is a passerine bird in the family Buphagidae. It was previously placed in the starling and myna family, Sturnidae.

It is native to the savannah of Sub-Saharan Africa from Senegal east to Sudan. It is least common in the extreme east of its range where it overlaps with the red-billed oxpecker, despite always dominating that species when feeding.


Facts Edit

The yellow-billed oxpeckers are two species of bird which make up the family Buphagidae. Some ornithologists regard them as a subfamily Buphaginae within the starling family Sturnidae but they appear to be quite distinct.

Oxpeckers are endemic to the savanna of Sub-Saharan Africa. Both the English and scientific names arise from their habit of perching on large mammals (both wild and domesticated) such as cattle or rhinoceroses, and eating ticks, botfly larvae, and other parasites.

According to the more recent studies of Muscicapoidea phylogeny, the oxpeckers are an ancient line related to Mimidae (Mockingbirds and Thrashers) and starlings but not particularly close to either. Considering the known biogeography of these groups, the most plausible explanation seems that the oxpecker lineage originated in Eastern or Southeastern Asia like the other two.

This would make the two species of Buphagus something like living fossils and demonstrates that such remnants of past evolution can possess striking and unique autapomorphic adaptations. In the last episode of Walking with Dinosaurs, after it was fast-foward to the modern African plains, the oxpeckers are seen, alongside many other birds, and they are described as living dinosaurs.

In the episode, The Walking Ape, the oxpeckers reside in the Aviary.
