Cuckoos are brood parasites, which means that they lay their eggs in the nests of other bird species, such as meadow pipits and reed warblers.
The female cuckoo will lay a single egg in each nest, which hatches after around 12 days.
The cuckoo chick then pushes the other eggs or chicks out of the nest and is raised by the host parents, who feed it until it fledges at around 17-21 days old.
Cuckoos breed in a variety of habitats, including woodland, heathland, moorland, and grassland.
They prefer areas with a mix of open ground and trees or bushes, where they can find both food and shelter.
Cuckoos are insect-eaters, and their diet consists mainly of caterpillars, which they catch on the wing.
They will also feed on other insects, such as beetles and bugs.
