|On Norfolk Island, Australia|
The Norfolk parakeet (Cyanoramphus cookii), also called Tasman parakeet, Norfolk Island green parrot or Norfolk Island red-crowned parakeet, is a species of parrot in the family Psittaculidae. It is endemic to Norfolk Island (located between Australia, New Zealand and New Caledonia in the Tasman Sea). The species was once considered a subspecies of the red-fronted parakeet of New Zealand. The name Tasman parakeet is used by Christidis and Boles on the argument that this species and the Lord Howe red-crowned parakeet (Cyanoramphus novaezelandiae subflavescens) are probably a single species for which they use biogeographical arguments. Tasman is used for other species with the same distribution and they propose that name for that reason. However, the latter subspecies was not included in the genus-wide phylogenetic reconstruction using DNA sequences, and the lumping of the species should be considered tentative.
This species of parakeet was down to only 4 breeding females and 28–33 males in 1994, but its population has since rebounded to 200–300 birds. It is only found in Norfolk Island National Park and the surrounding area.
