Scientific name: Cuculus canorus
Nature Stars: 60
About the size of a Collared Dove, Cuckoos are a scarce summer visitor to most of Britain, arriving in April. The adults leave for Africa almost as soon as they have laid their eggs, by June or July, while the young birds follow them in the autumn.
Cuckoos are famous for laying their eggs in the nests of other birds such as dunnocks, reed warblers and meadow pipits. They play no part in raising their chicks.

How to identify: Cuckoos are sometimes mistaken for Sparrowhawks when flying. However, if seen well, a Cuckoo is unmistakeable.
Where: A widespread summer visitor.
Fantastic fact: Adult cuckoos feed almost entirely on big hairy caterpillars!
