The common cuckoo is the only cuckoo that says its name.

A cuckoo is not like every other bird.

Nearly every other bird lay eggs and keeps them in their own nest.

A cuckoo lays its eggs in another birds nest. When the young cuckoo is born featherless and blind, it heaves all the other eggs and chicks onto its back and out of the nest.

The North American cuckoo doesn't live in other birds nests.
