Great Spotted Cuckoo

11 tinting in trees and bushes for its prey, this cuckoo eats hairy caterpillars that most other birds find distasteful. It also takes other insects, particularly grasshoppers and locusts, and other small creatures. Usually silent, it becomes noisy when breeding, with a song that is partly a harsh chatter and partly a gobbling sound. After hatching, the young cuckoo imitates the calls of the nestlings of the host species, begging for food from the parent. Before long it outgrows the other young birds, though it does not eject them from the nest.

Common Cuckoo
