The African emerald cuckoo (Chrysococcyx cupreus) is a species of cuckoo that is native to Africa. The African emerald cuckoo is sexually dimorphic. The males have a green back and head with a yellow breast. Females are barred green and brown on their backs and green and white on their breasts. The cuckoo's diet consists many of insects like caterpillars and ants. The diet can be supplemented with some fruit, and the African emerald cuckoo often forages in the middle and top layers of the canopy.
Like most cuckoos, the African emerald cuckoo is a brood parasite. Female African emerald cuckoos lay eggs in the nests of other bird species. A female cuckoo can lay between 19-25 eggs on average per breeding season. The breeding season occurs during the rainy seasons, generally during the months between September and March. Even though the cuckoo do not need territory (animal) to feed fledglings, male African emerald cuckoos still maintain a territory to display itself to potential mates.
