Brief introduction: The Common Cuckoo (Cuculus canorus canorus (Linnaeus, 1758)), also known as the European Cuckoo, is a widespread summer migrant to Europe and Asia. It is a brood parasite, meaning it lays eggs in other birds' nests; particularly in Dunnock's, Meadow Pipit's, and Eurasian Reed Warbler's nests.
