Birds

In this list of New Zealand birds, Māori names (where known) are given first, followed by English alternatives. In some cases (tui, kākā, weka, pūkeko, moa, kiwi, kea, kōkako, takahē) the Māori name is the common name. In other cases (fantail, albatross, black-backed gull, bellbird, morepork, dotterel, wax-eye, oystercatcher) the English name is most commonly used.This list's taxonomic treatment and nomenclature (common and scientific names) mainly follows the conventions of The Clements Checklist of Birds of the World, 2016 edition.[1] Some supplemental referencing is that of the Avibase Bird Checklists of the World[2] as of January 2017.The species and subspecies marked extinct became extinct subsequent to humans' arrival in New Zealand. About two thirds of the extinctions occurred after the arrival of Māori but before the arrival of Pākehā and the rest since Pākehā arrived.Unless otherwise noted, all species listed below are considered to occur regularly in New Zealand as permanent residents, summer or winter visitors, or migrants. The following codes are used to denote other categories of species:(B) Breeding - confirmed nesting records in New Zealand or a portion thereof. (I) Introduced - a species introduced to New Zealand by the actions of humans, either directly or indirectly (X) Extinct - a species that no longer exists (ex) Extirpated - a species no longer found in New Zealand or a portion thereof but existing elsewhere (P) - a regularly occurring in New Zealand or a portion thereof. The species occurs on an annual or mostly annual basis, but does not nest in New Zealand. (V) Vagrant - a species rarely occurring in New Zealand or a portion thereof.The Checklist of the birds of New Zealand, published in 2010 by Te Papa Press, in association with the Ornithological Society of New Zealand, is an authoritative list of New Zealand birds.http://nzbirdsonline.org.nz/sites/all/files/checklist/Checklist-of-Birds.pdf
