. The sexes are similar, the head, upper parts and wings being dark grey, the throat and breast pale grey and the belly white barred with dark grey. The tail is dark grey with dark barring and a white tip. The eye is yellow in the male and light brown in the female. The beak is yellow, tipped with black or horn. The legs and feet are yellowish. The juvenile has two colour forms; the grey morph is greyer than the adult with white barring, the underparts being creamy-white with dense dark barring; the hepatic morph is brown rather than grey, the white being replaced by buff or a tawny hue. The call of the male is a "coo-coo" with the second note higher and louder than the first. The female utters a bubbling "Kwik-kwik-kwik".

Ecology

This species is generally solitary. It feeds in trees and on the ground for insects, foraging through the foliage and probing cattle dung. The diet consists mainly of both hairy and smooth caterpillars, but also includes other insects such as beetles and winged termites. It perches almost vertically. The male is territorial, and in southern Africa, a pair of African cuckoos occupy a territory of greater than , driving off other cuckoos. Like many other

(''Dicrurus adsimilis'') are often targeted . Incubation lasts between twelve and seventeen days, but usually twelve days, with the eggs hatching before those of the host. The cuckoo chick ejects from the nest any other eggs and nestlings it encounters. Its eyes open after eight days and it fledges in three weeks, remaining dependent on its foster parents for several more weeks. Breeding success rate in South Africa is up to 38 percent, and one yellow-billed shrike nest was abandoned by the foster-parents before the cuckoo chick fledged, with a new nest being built elsewhere. A study in Zambia releveled that African cuckoo would have its eggs rejected by a fork-tailed drongo host with rate of rejection as high as 93.7%.
