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.[1] They form an archipelago in the Pacific Ocean about 650 kilometres (400 mi) east of mainland New Zealand. This list's taxonomic treatment and nomenclature (common and scientific names) mainly follows the conventions of The Clements Checklist of Birds of the World, 2022 edition.[2] Some supplemental referencing is that of the Avibase Bird Checklists of the World [3] as of October 2022.
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 (European New Zealanders) 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 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 Chatham Island birds.
Order: Anseriformes Family: Anatidae
The family Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These are adapted for an aquatic existence, with webbed feet, bills that are flattened to a greater or lesser extent, and feathers that are excellent at shedding water due to special oils.
Order: Galliformes Family: Odontophoridae
Odontophoridae are not native to the Chatham Islands, but feral populations of one species survives.
Order: Columbiformes Family: Columbidae
Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere.
Order: Cuculiformes Family: Cuculidae
The family Cuculidae includes cuckoos, roadrunners and anis. These birds are of variable size with slender bodies, long tails and strong legs. The Old World cuckoos are brood parasites.
Order: Caprimulgiformes Family: Apodidae
Swifts are small birds which spend the majority of their lives flying. These birds have very short legs and never settle voluntarily on the ground, perching instead only on vertical surfaces. Many swifts have long swept-back wings which resemble a crescent or boomerang.
Order: Gruiformes Family: Rallidae
Rallidae is a large family of small to medium-sized birds which includes the rails, crakes, coots and gallinules. Typically they inhabit dense vegetation in damp environments near lakes, swamps or rivers. In general they are shy and secretive birds, making them difficult to observe. Most species have strong legs and long toes which are well adapted to soft uneven surfaces. They tend to have short, rounded wings and to be weak fliers.
Order: Charadriiformes Family: Recurvirostridae
Recurvirostridae is a family of large wading birds, which includes the avocets and stilts. The avocets have long legs and long up-curved bills. The stilts have extremely long legs and long, thin straight bills.
Order: Charadriiformes Family: Haematopodidae
The oystercatchers are large and noisy plover-like birds, with strong bills used for smashing or prising open molluscs.
Order: Charadriiformes Family: Charadriidae
The family Charadriidae includes the plovers, dotterels and lapwings. They are small to medium-sized birds with compact bodies, short, thick necks and long, usually pointed, wings. They are found in open country worldwide, mostly in habitats near water.
Order: Charadriiformes Family: Scolopacidae
Order: Charadriiformes Family: Stercorariidae
The family Stercorariidae are, in general, medium to large birds, typically with grey or brown plumage, often with white markings on the wings. They nest on the ground in temperate and arctic regions and are long-distance migrants.
Order: Charadriiformes Family: Laridae
Laridae is a family of medium to large seabirds, the gulls, terns, and skimmers. Gulls are typically grey or white, often with black markings on the head or wings. They have stout, longish bills and webbed feet. Terns are a group of generally medium to large seabirds typically with grey or white plumage, often with black markings on the head. Most terns hunt fish by diving but some pick insects off the surface of fresh water. Terns are generally long-lived birds, with several species known to live in excess of 30 years. Skimmers are a small family of tropical tern-like birds. They have an elongated lower mandible which they use to feed by flying low over the water surface and skimming the water for small fish.
Order: Sphenisciformes Family: Spheniscidae
Penguins are a group of aquatic, flightless birds living almost exclusively in the Southern Hemisphere, especially in Antarctica.
Order: Procellariiformes Family: Diomedeidae
The albatrosses are a family of large seabird found across the Southern and North Pacific Oceans. The largest are among the largest flying birds in the world.
Order: Procellariiformes Family: Oceanitidae
The southern 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: Procellariiformes Family: Hydrobatidae
Though the members of this family are similar in many respects to the southern storm-petrels, including their general appearance and habits, there are enough genetic differences to warrant their placement in a separate family.
Order: Procellariiformes Family: 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: Suliformes Family: Fregatidae
Frigatebirds are large seabirds usually found over tropical oceans. They are large, black-and-white, or completely black, with long wings and deeply forked tails. The males have colored inflatable throat pouches. They do not swim or walk and cannot take off from a flat surface. Having the largest wingspan-to-body-weight ratio of any bird, they are essentially aerial, able to stay aloft for more than a week.
Order: Suliformes Family: Sulidae
The sulids comprise the gannets and boobies. Both groups are medium-large coastal seabirds that plunge-dive for fish.
Order: Suliformes Family: Phalacrocoracidae
Cormorants are medium-to-large aquatic birds, usually with mainly dark plumage and areas of coloured skin on the face. The bill is long, thin and sharply hooked. Their feet are four-toed and webbed, a distinguishing feature among the order Pelecaniformes.
Order: Pelecaniformes Family: Ardeidae
The family Ardeidae contains the bitterns, herons, and egrets. Herons and egrets are medium to large wading birds with long necks and legs. Bitterns tend to be shorter necked and more wary. Members of Ardeidae fly with their necks retracted, unlike other long-necked birds such as storks, ibises and spoonbills.
Order: Pelecaniformes Family: Threskiornithidae
Threskiornithidae is a family of large terrestrial and wading birds which includes the ibises and spoonbills. They have long, broad wings with 11 primary and about 20 secondary feathers. They are strong fliers and despite their size and weight, very capable soarers.
Order: Accipitriformes Family: Accipitridae
Accipitridae is a family of birds of prey, which includes hawks, eagles, kites, harriers and Old World vultures. These birds have powerful hooked beaks for tearing flesh from their prey, strong legs, powerful talons and keen eyesight.
Order: Strigiformes Family: Strigidae
The typical owls are small to large solitary nocturnal birds of prey. They have large forward-facing eyes and ears, a hawk-like beak, and a conspicuous circle of feathers around each eye called a facial disk.
Order: Coraciiformes Family: Alcedinidae
Kingfishers are medium-sized birds with large heads, long pointed bills, short legs, and stubby tails.
Order: Falconiformes Family: Falconidae
Falconidae is a family of diurnal birds of prey. They differ from hawks, eagles, and kites in that they kill with their beaks instead of their talons.
Order: Psittaciformes Family: Strigopidae
The New Zealand parrot superfamily, Strigopoidea,[4] consists of at least three genera of parrots – Nestor, Strigops, the fossil Nelepsittacus,[5][6] and probably the fossil Heracles.[7] The genus Nestor consists of the kea, kaka, Norfolk Island kaka and Chatham Island kaka,[8][9] while the genus Strigops contains the iconic kakapo.[8] All extant species are endemic to New Zealand. The species of the genus Nelepsittacus were endemics of the main islands, while the two extinct species of the genus Nestor were found at the nearby oceanic islands such as Chatham Island of New Zealand, and Norfolk Island and adjacent Phillip Island.
Order: Psittaciformes Family: Psittaculidae
Characteristic features of parrots include a strong curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly coloured, and some are multi-coloured. In size they range from 8 cm (3.1 in) to 1 m (3.3 ft) in length. Old World parrots are found from Africa east across south and southeast Asia and Oceania to Australia and New Zealand.
Order: Passeriformes Family: Meliphagidae
The honeyeaters are a large and diverse family of small to medium-sized birds most common in Australia and New Guinea. They are nectar feeders and closely resemble other nectar-feeding passerines.
Order: Passeriformes Family: Acanthizidae

Order: Passeriformes Family: Petroicidae
Most species of Petroicidae have a stocky build with a large rounded head, a short straight bill and rounded wingtips. They occupy a wide range of wooded habitats, from subalpine to tropical rainforest, and mangrove swamp to semi-arid scrubland. All are primarily insectivores, although a few supplement their diet with seeds.
Order: Passeriformes Family: Alaudidae
Larks are small terrestrial birds with often extravagant songs and display flights. Most larks are fairly dull in appearance. Their food is insects and seeds.
Order: Passeriformes Family: Locustellidae
Locustellidae are a family of small insectivorous songbirds found mainly in Eurasia, Africa, and the Australian region. They are smallish birds with tails that are usually long and pointed, and tend to be drab brownish or buffy all over.
Order: Passeriformes Family: Hirundinidae
The family Hirundinidae is adapted to aerial feeding. They have a slender streamlined body, long pointed wings, and a short bill with a wide gape. The feet are adapted to perching rather than walking, and the front toes are partially joined at the base.
Order: Passeriformes Family: Zosteropidae
The white-eyes are small birds of rather drab appearance, the plumage above being typically greenish-olive, but some species have a white or bright yellow throat, breast, or lower parts, and several have buff flanks. As the name suggests, many species have a white ring around each eye.
Order: Passeriformes Family: Sturnidae

Order: Passeriformes Family: Fringillidae
Finches are seed-eating passerine birds, that are small to moderately large and have a strong beak, usually conical and in some species very large. All have twelve tail feathers and nine primaries. These birds have a bouncing flight with alternating bouts of flapping and gliding on closed wings, and most sing well.
Order: Passeriformes Family: Emberizidae
The emberizids are a large family of passerine birds. They are seed-eating birds with distinctively shaped bills. Many emberizid species have distinctive head patterns.
