The genus
Nelepsittacus consists of four extinct parrot species and is closely related to the genus
Nestor. All recovered from early Miocene
Saint Bathans Fauna from the Lower Bannockburn Formation in Otago in New Zealand, three of the four species have been named. Features in their skeletons, namely the
coracoid,
humerus,
tibiotarsus, and
tarsometatarsus, that they share only with the
Nestor parrots link them to that genus.
