The kākāpō (/ˈkɑːkəpoʊ/ KAH-kə-poh; Māori: [kaːkaːpɔː]; from the Māori: kākāpō, lit. 'night parrot'), also known as owl parrot (Strigops habroptilus), is a species of large, flightless, nocturnal, ground-dwelling parrots of the super-family Strigopoidea, endemic to New Zealand. Up to 64 cm (25 in) in length, these flightless birds have finely blotched yellow-green plumage, a distinct facial disc, owl-style forward-facing eyes with surrounding discs of specially-textured feathers, a large grey beak, short legs, large blue feet, and relatively short wings and tail: a combination of traits making it unique among parrots. It is the world's only flightless parrot, the world's heaviest parrot, and also is nocturnal, herbivorous, visibly sexually dimorphic in body size, has a low basal metabolic rate, and does not have male parental care. It is the only parrot to have a polygynous lek breeding system. It is also possibly one of the world's longest-living birds, with a reported lifespan of up to 100 years.
