New Zealand is home to three species of parrots: Keas, Kakas, and Kakapos. Keas are the world's only alpine parrot, and are known for their intelligence and curiosity. Kakas are large, forest-dwelling parrots that are mostly found in the North Island of New Zealand. Kakapos are the world's only flightless parrot, and are critically endangered due to predation by introduced mammals. All three species are endemic to New Zealand, and are an important part of the country's biodiversity.
