The mousebirds (family Coliidae) is a family of birds belonging to the monotypic order Coliiformes. This family of gregarious birds are mostly arboreal, named after their habit of creeping through branches to feed on fruits and flowers in the trees. In addition, their buff plumage reminds of rodent fur. The family is endemic to the Afrotropical open woodlands, and all species share a very long tail and a distinctive crest.
The family comprises 6 species in 2 genera. Genus Urocolius (2 species) is featured by bright red facial skin connecting bill and eye, whereas genus Colius (4 species) are generally more buff and plain-colored.
