The white-backed mousebird (Colius colius, valkoperähiiro in Finnish) is a large species of mousebird. It is about 34 cm long, with the tail (which is not very visible in the picture) comprising approximately half the length. It is distributed in western and central regions of southern Africa from Namibia and southern Botswana eastwards to Central Transvaal and the eastern Cape. I took this picture in Richersveld, near the boarder of South Africa and Namibia.
This bird is a frugivore which subsides on fruits, berries, leaves, seeds and nectar. Its feeding habits make it very unpopular with fruit farmers and domestic gardeners, which might be why it is very shy as a rule. When it spots a human it either sits quiet in a tree or takes off immediately.
