Order PSITTACIFORMES: Cockatoos, Parrots and Parakeets New molecular data and analyses support a view that the two subfamilies Strigopinae and Nestorinae form a single clade basal to all other Recent members of the order Psittaciformes (e.g. de Kloet & de Kloet 2005, Astuti et al. 2006, Tokita et al. 2007, Wright et al. 2008). They therefore need to be put in a family of their own (rather than in Psittacidae, e.g. Checklist Committee 1990) placed ahead of Cacatuidae in the systematic list. The name Strigopidae G.R. Gray, 1848 has priority.

For general discussion of speciation in the genus see Taylor (1985), Boon, Daugherty et al. (2001), Kearvell et al. (2003) and Rawlence (2006). Identifications for fossil bones of Cyanoramphus are tentative because most bones (particularly isolated ones) cannot be reliably assigned to species due to overlap in size.

New Zealand. Now more common on the mainland than the red-crowned parakeet. North Island: mainly restricted to central forested areas and the Tararua Range; present on Manawatäwhi / Three Kings, Hen and Chickens, Hauturu / Little Barrier, Cuvier (Repanga) and Kapiti Islands. South Island: widespread in western Marlborough, Nelson, Westland, inland North Canterbury, western Otago, the Catlins and Fiordland; Chetwode Islands. Present on Stewart Island / Rakiura and outliers (Big and Little Solander, Bench, Ulva, Jacky Lee (Pukeokaoka), Codfish (Whenuahou) and Taukihepa / Big South Cape Islands). Auckland Islands. Cyanoramphus auriceps previously included the subspecies C. a. malherbi (South Island) and C. a. forbesi (Chathams), but these are now listed as full species. Members of C. auriceps formerly present on the Auckland Islands have recently been shown by molecular methods (Rawlence 2006) to be a distinct clade contained within the mainland form, but with some evidence of hybridisation with C. malherbi before 1942–43. There is now extensive hybridisation between C. auriceps and C. n. novaezelandiae on the Auckland Islands (Adams and Enderby) and the former taxon may no longer exist as a discrete genetic entity in these locations; it is retained here as C. auriceps pending publication of further information.
