What is the Cuckoo?

The cuckoo is a bird in the family Cuculidae. There are many different species of cuckoo, and they vary greatly in size and color.

Cuckoos are birds of flight who migrate to warmer climates during the winter. Some cuckoos travel several thousand miles during their migration each year.

Cuckoos are insectivores, but some species will also eat small animals such as frogs and other birds. Many also enjoy eating fruits and berries.

How Did the Cuckoo Get Its Name?

The cuckoo’s name comes from the distinctive song it sings during breeding season: “coo-coo, coo-coo.” Male cuckoos sing this song to attract females, and females sing a bubbly-sounding response during courtship rituals.

The cuckoo’s birdsong is musical and flute-like; it sounds very similar to the calls of some doves, specifically mourning doves and collared doves. The cuckoo’s song is distinguished by the fact that it has only two syllables, with the emphasis on the first syllable.
