Families and Genera

The Strigopoidea is a small superfamily of New Zealand parrots.[1] It only has three genera: Nestor, the Kakapo Strigops and the fossil Nelepsittacus.[2]

The genus Nestor consists of the Kea, and the Kaka,[3][4] while the genus Strigops contains the iconic Kākāpō.[3] All living species are endemic to New Zealand. The modern common species names, Kea, Kākā and Kākāpō, are the same as the original Māori names.

The nearby island species, the Norfolk Kaka and the Chatham Kaka, became extinct in recent times.[4][5] The extinct species of the genus Nelepsittacus have been extinct for 16 million years. All living forms are threatened.[6][7][8] Human activity caused the two extinctions and the decline of the other three species. Settlers introduced invasive species, such as pigs and possums, which eat the eggs of ground nesting birds. Also hunting for food, killing as agricultural pests, habitat loss, and introduced wasps have added to the problem.

The family diverged from the other parrots around 82 million years ago when New Zealand broke off from Gondwana, and the ancestors of the genera Nestor and Strigops diverged from each other between 60 and 80 million years ago.[9][10]
