The Kakapo is the heaviest, only flightless, and only nocturnal parrot in the world. It is related to the kaka and kea parrots found in New Zealand forests and mountains, but otherwise has no close relatives. Despite its size and inability to fly, the Kakapo has evolved to live a long life of over 60 years by hiding well but also having a strong smell that makes it easy for predators to find.
