The malachite kingfisher (Corythornis cristatus) is a river kingfisher which is widely distributed in Africa south of theSahara. It is largely resident except for seasonal climate-related movements.
This is a small kingfisher, 13 cm (5.1 in) in length. The general colour of the upper parts of the adult bird is bright metallic blue. The head has a short crest of black and blue feathers, which gives rise to the scientific name. The face, cheeks, and underparts are rufous and white patches are on the throat and rear neck sides.
The bill is black in young birds and reddish-orange in adults; the legs are bright red. Sexes are similar, but juveniles are a duller version of the adult. source
