The Cuckoo: Close Up HD Footage (Cuculus canorus)

The cuckoo is a migratory bird that breeds in Europe and Asia before flying to Africa for winter. They're known for their distinctive call that sounds like "cuck-oo". The male cuckoo doesn't build a nest or rear the young. Instead, the female lays her eggs in other birds' nests, tricking them into raising the cuckoo chick. This behaviour is called brood parasitism. The cuckoo chick grows rapidly and pushes out the host's eggs or chicks to get all the food. Cuckoos feed mostly on insects like caterpillars and beetles. They're a greyish bird with a slender body and long tail feathers. In Britain, hearing the cuckoo's call in spring is considered a sign of the changing seasons.
