North Island kākā. New Zealand is geographically isolated, and originally lacked any mammalian predators, hence parrots evolved to fill habitats from the ground dwelling kākāpō to the alpine dwelling kea as well as a variety of forest species.
Earlier ornithologists felt that the kākāpō might be related to the ground parrots and night parrot of Australia due to their similar colouration, but this is contradicted by molecular studies; [25] rather, the cryptic colour seems to be adaptation to terrestrial habits that evolved twice convergently.
The New Zealand parrot family, Strigopidae, [1] consists of at least three genera of parrots – Nestor, Strigops, the fossil Nelepsittacus, [2] [3] and probably the fossil Heracles. [4] The genus Nestor consists of the kea , kākā , Norfolk kākā and Chatham kākā , [ 5 ] [ 6 ] while the genus Strigops contains the iconic kākāpō . [ 5 ]
The kākāpō, also known as owl parrot (Strigops habroptilus), is a species of large, flightless, nocturnal, ground-dwelling parrot of the super-family Strigopoidea, endemic to New Zealand. [ 12 ] Species
The New Zealand kākā (Nestor meridionalis) is a large species of parrot of the family Strigopidae found in New Zealand's native forests across the three main Islands of New Zealand. The species is often known by the abbreviated name kākā , although it shares this name with the recently extinct Norfolk kākā and Chatham kākā .

New Zealand had more species of flightless birds (including the kiwi, several species of penguins, the takahē, the weka, the moa, and several other extinct species) than any other such location. One reason is that until the arrival of humans roughly a thousand years ago, there were no large mammalian land predators in New Zealand; the main ...
