Cuckoo Bird: Nest Life

Play a cuckoo chick: hatch, beg, grow huge, and fledge in 12 real birds' nests. Collect skins, ace nature quizzes, and discover why there are no bad birds.

Meet the cuckoo: nature's boldest little freeloader.

In Cuckoo, you play a newly hatched cuckoo chick dropped into a stranger's nest. Hatch from your egg, make room for yourself, beg your unwitting foster parents into feeding you, grow into a comically oversized chick, then fledge and fly off to find your next host nest. One quick loop, then again — each in a different bird's nest, with new challenges every time.

It's based on one of the most astonishing true stories in the natural world. Every mechanic in the game is real cuckoo behavior, just slightly cartoonish.

THERE ARE NO BAD BIRDS Cuckoo celebrates nature exactly as it is. The cuckoo isn't a villain — it's a marvel of evolution doing precisely what it was born to do. No blood, no cruelty, just wonder.

Free to play. No accounts, no nonsense. Just you, a tiny trespasser, and a whole world of nests to discover.
