The genus Nestor is one of two genera of the family Nestoridae. Together with the Kakapo in the Strigopidae tribe, they form the small parrot superfamily Strigopoidea. The genus Nestor contains two extant parrot species from New Zealand and two extinct species from Norfolk Island, Australia and Chatham Island, New Zealand, respectively. All species are large stocky birds with short squarish tails.

Species

There are two surviving species and at least one well documented extinct species in the genus Nestor. Very little is known about the fourth, the Chatham kaka, which may have been conspecific with another kaka species.
