Black Cuckoo
Cuculus clamosus
The black cuckoo is a medium-sized cuckoo. The sexes are similar, the plumage varying by subspecies; Cuculus clamosus clamosus has upper parts black glossed with green, slatey-grey wings and black tail tipped with white and sometimes with the outer feathers barred or spotted with white or buff; Cuculus clamosus gabonensis is mostly black with a red throat and black and white barring on the belly.

Common Cuckoo
Cuculus canorus
The common cuckoo is 32–34 centimetres (13–13 in) long from bill to tail, with a tail of 13–15 centimetres (5.1–5.9 in) and a wingspan of 55–60 centimetres (22–24 in). The legs are short. It has a greyish, slender body and long tail, similar to a sparrowhawk in flight, where the wingbeats are regular. During the breeding season, common cuckoos often settle on an open perch with drooped wings and raised tail. There is a rufous colour morph, which occurs occasionally in adult females but more often in juveniles.
