* Nestor ( genus ), a genus of parrots in ornithology

The genus Nestor contains four species: the New Zealand Kaka ( Nestor meridionalis ), the Kea ( N. notabilis ), the extinct Norfolk Kaka ( N. productus ) and the extinct Chatham Kaka ( N.

The common ancestor of the Kakapo and the genus Nestor became isolated from the remaining parrot species when New Zealand broke off from Gondwana, around 82 million years ago.

Around 70 million years ago, the kakapo diverged from the genus Nestor.

Recent phylogenetic studies have confirmed the unique position of this genus as well as the closeness to the Kākā and the Kea, both belonging to the New Zealand parrot genus Nestor.

The genus Nestor is one of two genera of the family Nestoridae.

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 four species in the genus Nestor are thought to stem from a ' proto-Kākā ', dwelling in the forests of New Zealand 5 million years ago.

There are two surviving species and at least one well documented extinct species in the genus Nestor.
