The Kakapo Parrot of New Zealand, Strigops habroptilus also called owl parrots are large, flightless, nocturnal, ground dwelling parrots that live in New Zealand. It is the world's only flightless parrot, the heaviest parrot, nocturnal, herbivorous, visibly sexually dimorphic in body size, has a low basal metabolic rate, no male parental care, and is the only parrot to have a polygynous lek breeding system. It is also possibly one of the world's longest-living birds
One of the rarest birds of all is New Zealand's Kakapo, which is a flightless bird. The species has been largely wiped out by introduced predatory mammals such as feral cats, stoats, and possum; being hunted as game and for its feathers; and they reproduce only every 3-5 years. For over 100 years New Zealand has made efforts to protect the species. In 1989 it instituted a new recovery program, and now can be seen a slow but steady increase in numbers.
