Smith's bush squirrel (Paraxerus cepapi) sitting in a tree. This small rodent has an omnivorous diet, feeding on seeds, fruits, nuts, insects and birds' eggs. It lives in savanna and forest habitats in Africa, from Angola to Zambia and from Tanzania to Botswana. A conspicuous feature of their behaviour when under threat is 'mobbing'. This entails all the members of the colony make harsh clicking sounds while they flick their tails, building up momentum and gradually getting louder. Photographed in Mana Pools, Zimbabwe.
