Nesting: The Cuckoo is a brood parasite, it lays its eggs in other birds' nests and leaves the host birds to incubate and rear its young. Dunnocks, Robins and Meadow Pipits are frequent host birds. Each female Cuckoo specialises in using a particular host species and will lay eggs with similar markings to the host bird's eggs, and the young Cuckoo will imitate the begging calls of the host's chicks. When the Cuckoo nestling hatches, it instinctively pushes the other eggs and nestlings out of the nest.


Where to see: Cuckoos can be seen throughout the UK, but are especially numerous in southern and central England.
