The cuckoo, common cuckoo, European cuckoo or Eurasian cuckoo is a member of the cuckoo order of birds, Cuculiformes, which includes the roadrunners, the anis and the coucals.
Region
Palearctic (breeding) and sub-Saharan Africa (wintering)
Typical Environment
Breeds widely across Europe and temperate Asia wherever suitable host passerines are abundant. Prefers open woodlands, forest edges, heathlands, moorland, farmland with hedgerows, and reedbeds. Avoids dense, continuous forest and very arid habitats. In winter it occupies African savannas, woodland edges, and scrub. It follows host-rich mosaics of habitats rather than any single vegetation type.

The common cuckoo is famous for brood parasitism, laying its eggs in the nests of other smaller birds and leaving them to raise the chick. Females often mimic the egg pattern of their host species, and the chick instinctively ejects the host’s eggs or chicks. The male’s “cuck-oo” call is one of the most recognizable sounds of spring in Europe. They are long‑distance migrants, breeding across the Palearctic and wintering in Africa.

Temperament
solitary and secretive
Flight Pattern
strong flier with swift, direct flight and brief glides
Social Behavior
Typically solitary outside of brief courtship chases. Does not build its own nest; females lay single eggs in host nests, often removing one host egg. Hosts include warblers, pipits, wagtails, and other small passerines. Territorial males advertise and attract females with persistent calling.
Migratory Pattern
Seasonal migrant
Song Description
The male’s resonant two-note “cuck-oo” carries over long distances and is a hallmark of spring across much of Europe. Females give a rapid, bubbling call. Calls are most frequent during the breeding season and can trigger alarm in some host species.
