The genus Nestor is one of the two extant genera of the parrot family Strigopidae. Together with the kākāpō, and the extinct parrots in the genus Nelepsittacus, they form the parrot superfamily Strigopoidea. The Nestor's genus 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. A defining characteristic of the genus is the tongue, which is tipped with a hair-like fringe. The superficial resemblance of this tongue to that of lorikeets has led some taxonomists to consider the two groups closely related, but DNA evidence shows they are not.
The night parrot is a small parrot endemic to the continent of Australia. It has also been known as porcupine parrot, nocturnal ground parakeet, midnight cockatoo, solitaire, spinifex parrot and night parakeet. It is one of the most elusive and mysterious birds in the world, with no confirmed sightings of the bird between 1912 and 1979, leading to speculation that it was extinct. Sightings since 1979 have been extremely rare and the bird's population size is unknown, though based on the paucity of records it is thought to number between 50 and 249 mature individuals, and it is classified by the IUCN as a critically endangered species.
Caique refers to a group of four species of parrots in the genus Pionites endemic to the Amazon Basin in South America.
The ground parrot is a parrot endemic to Australia. It is one of only four ground-dwelling parrots in the world, the others being the closely related night parrot, the Antipodes parakeet, and the flightless kākāpō from New Zealand.
Eos is a genus of parrots belonging to the lories and lorikeets tribe of the family Psittaculidae. There are six species which are all endemic to islands of eastern Indonesia, most within very restricted ranges. They have predominantly red plumage with blue, purple or black markings. Males and females are similar in appearance.
Pyrilia is a genus of parrots in the family Psittacidae. It was recently split from the now-monotypic Pionopsitta, and then briefly moved to Gypopsitta. But as Pyrilia was published a few months before Gypopsitta, the latter is a junior synonym.
