The Diederik Cuckoo (Chrysococcyx caprius), formerly Dideric Cuckoo or Didric Cuckoo, is a member of the cuckoo order of birds, the Cuculiformes, which also includes the roadrunners, the anis, and the Hoatzin.
It is a very common resident breeder in Africa south of the Sahara Desert. It is a short-distance seasonal migrant, moving with the rains. It is a solitary bird, found in open woodland, savanna and riverside bushes. It has been recorded as far north as Cyprus (1982).
The Diederik Cuckoo is a brood parasite. It lays a single egg mostly in the nests of weavers, especially the Village Weaver and the bishops in the genus Euplectes.
The Diederik Cuckoo is a smallish cuckoo at 18 to 20 cm. Adult males are green above with copper-sheened areas on the back and whitish underparts. They have a broken white eyestripe, a green moustauchial stripe, and green outer tail feathers with small white spots.
