The closely related species, C. amethystinus has a glossy blue-violet throat patch rather than reddish violet of this cuckoo.

Habitats of Violet Cuckoo
The natural habitats of Violet Cuckoo are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests. It is also seen in gardens, orchards and rubber plantations. It occurs from lowlands up to 1500m, but mainly below 700m. The Southern populations are resident, while northern populations in places like Assam and Bangladesh appear to be migratory.
Feeding of Violet Cuckoo
Violet Cuckoos are insectivorous but they will also eat fruit. They have been seen shaking hairy caterpillars to remove the stomach contents for consumption.
Forage of Violet Cuckoo
The forage of Violet Cuckoo is by creeping up and down branches, but they can also fly catch on the wing.
Eggs of Violet Cuckoo
Violet Cuckoo is brood parasite and lays eggs in the nests of other birds. The males are active and vocal during the breeding season in order to attract mates. Once they have mated, the females become secretive as they search for appropriate nests in which to lay their eggs.
Host species recorded for the violet cuckoo are sunbirds and spider hunters (thirteen species of the genus Arachnothera, small birds related to sunbirds). Host species often recognise adult cuckoos as a threat and chase them off, but then do not recognise that the cuckoo eggs in the nest are aliens. Cuckoo chicks are usually larger than host chicks. The chicks of many cuckoo species have been observed to throw the host chicks out of the nest, although this behaviour has not been recorded for the violet cuckoo yet.
