The common cuckoo (Cuculus canorus) (formerly European cuckoo) is a member of the cuckoo order of birds. This species is a widespread summer migrant to Europe and Asia, and winters in Africa.It is a brood parasite, which means it lays eggs in the nests of other bird species. The image you are seeing here is of a Juvenile, a very far image and a big crop hence a little more noisy.
