The entire time from egg-laying to fledging may be as little as 17 days. Yellow-billed cuckoos occasionally lay eggs in the nests of other birds (most often the closely related black-billed cuckoo), but they are not obligate brood parasites of other birds as is the common cuckoo of Eurasia.
The great reed warblers' responses to the common cuckoo eggs varied: 66% accepted the egg(s); 12% ejected them; 20% abandoned the nests entirely; 2% buried the eggs. 28% of the cuckoo eggs were described as "almost perfect" in their mimesis of the host eggs, and the warblers rejected "poorly mimetic" cuckoo eggs more often.
Yellow-billed and black-billed cuckoos occasionally lay eggs in the nests of other birds, but are not obligate brood parasites like the common cuckoo of Eurasia. Northern species such as yellow-billed and black-billed cuckoos are strong migrants , wintering in Central or South America , and occasionally wander to western Europe as rare vagrants ...
The chestnut-breasted malkoha is typical of the Phaenicophaeinae in having brightly coloured skin around the eye.. Cuckoos are medium-sized birds that range in size from the little bronze cuckoo, at 17 g (0.6 oz) and 15 cm (6 in), to moderately large birds, ranging from 60–80 cm (24–31 in) in length, such as the giant coua of Madagascar, the coral-billed ground-cuckoo of Indochina, and ...
The female cuckoo in each case replaces one of the host's eggs with one of her own. The cuckoo egg hatches earlier than the host's, and the chick grows faster; in most cases the cuckoo chick evicts the eggs or young of the host species. Cuculus species lay coloured eggs to match those of their passerine hosts. Female cuckoos specialise in a ...

Like many other cuckoos, the African cuckoo is a brood parasite, the female laying her eggs in the nests of birds of other species, removing an egg already present in the nest. [3] Target hosts vary across the range, and the cuckoo's eggs usually closely match in colour and size the eggs of the host species; the yellow-billed shrike ...
These birds are of variable size with slender bodies, long tails, and strong legs. The Old World cuckoos are brood parasites.
