Cuculus canorus, Cuckoo, Gjøk. 33cm.
A fascinating summer visitor which is found in higher aboreal zones.
The polyandrous female lays up to 20 eggs, all in different nests, particularly in meadow pipits' nests. After hatching the young cookoo ejects the other eggs and young from the nest, and receives all the food its foster parents bring, until it is three times their size.
The adults are usually alike and eat any insects, even hairy caterpillars.
