All the Clamator cuckoos are brood parasites, which lay a single egg in the nests of medium-sized hosts, such as magpies, starlings, shrikes, laughingthrushes, bulbuls and babblers, depending on location. Unlike the common cuckoo, neither the hen nor the hatched chick of Clamator species evict the host's eggs, but the host's young often die because they cannot compete successfully with the cuckoo for food.
