List of birds of the Chatham Islands


In this list of Birds of the Chatham Islands. In 1995, Chatham Islands County was dissolved and reconstituted by a specific Act of Parliament as the "Chatham Islands Territory", with powers similar to those of territorial authorities and some functions similar to those of a regional council. They form an archipelago in the Pacific Ocean about 650 kilometres east of mainland New Zealand.
This list's taxonomic treatment and nomenclature mainly follows the conventions of The Clements Checklist of Birds of the World, 2016 edition. Some supplemental referencing is that of the Avibase Bird Checklists of the World as of January 2017.

The species and subspecies marked extinct became extinct subsequent to humans' arrival in the Chatham Islands. 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 the Chatham Islands as permanent residents, summer or winter visitors, or migrants. The following codes are used to denote other categories of species:
The , published in 2010 by Te Papa Press, in association with the Ornithological Society of New Zealand, is an authoritative list of Chatham Island birds.

Penguins

Order: SphenisciformesFamily: Spheniscidae
Penguins are a group of aquatic, flightless birds living almost exclusively in the Southern Hemisphere, especially in Antarctica.
Order: ProcellariiformesFamily: Procellariidae
The procellariids are the main group of medium-sized "true petrels", characterised by united nostrils with medium nasal septum, and a long outer functional primary flight feather.
Order: ProcellariiformesFamily: Oceanitidae
The austral storm petrels are the smallest seabirds, relatives of the petrels, feeding on planktonic crustaceans and small fish picked from the surface, typically while hovering. Their flight is fluttering and sometimes bat-like.
Order: ProcellariiformesFamily: Hydrobatidae
