The cuckoo is a bird from the family of cuckoos. She is known for her characteristic cry, which resembles a whistle. Cuckoos are common all over the world, they can be found in forests, fields and gardens. They feed on insects, which they catch in flight. Cuckoos are also known for their nests, which they build in tree hollows or on the ground. However, cuckoos do not build nests themselves, but lay eggs in the nests of other birds, which hatch their eggs and feed the cuckoo chicks.
