Note red legs of northern races.
The mousebirds are a small group of (possibly near passerine) birds, which have no known close affinities to other groups, though might be close to trogons and owls. The mousebirds are therefore given order status as Coliiformes. This group is confined to sub-Saharan Africa, and is the only bird order confined entirely to that continent. They had a wider range in prehistoric times and apparently evolved in Europe.
