Tokelau is a dependent territory of New Zealand in Polynesia in the Pacific Ocean, comprising three coral atolls with a total land area of 10.1 km (3.9 sq mi). There are 33 species of birds that have been recorded from Tokelau, of which one, the red junglefowl, has been introduced by humans. Anas ducks are also seasonal visitors to the islands. The most common species in Tokelau are the black noddy, brown noddy, and white tern, which each have populations of thousands of pairs on each of the atolls. Three species of birds found in Tokelau, the bristle-thighed curlew, bar-tailed godwit, and flesh-footed shearwater, are near-threatened. One species, the Australian masked-owl, is locally extinct. Before the arrival of humans, Tokelau may also have been inhabited by Halcyon kingfishers, Gallirallus and Porzana rails, Acrocephalus warblers, Aplonis starlings, Prosobonia sandpipers, and fruit doves.

Tokelau has a moist tropical climate year-round, with an average temperature of 28 °C (82 °F) and a mean annual rainfall of over 3,000 mm (120 in). The atolls consist of coral rubble of different sizes, with poor quality soil overlying coral rock. Plant diversity is low, with forest on the inner side of the atolls comprising mainly coconut palm, along with other tropical trees like Cordia subcordata, Pisonia grandis, Guettarda speciosa, and Pandanus. Undergrowth mainly consists of bird's-nest fern (Asplenium nidus). Vegetation nearer the beach is more diverse, with very little soil and plants like Scaevola taccada and Morinda citrifolia.

This list's taxonomic treatment (designation and sequence of orders, families, and species) and nomenclature (common and scientific names) follow the conventions of the 2022 edition of The Clements Checklist of Birds of the World. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account. Introduced and accidental species are included in the total counts for Tokelau.

The following tags have been used to highlight several categories. Not all species fall into one of these categories. Those that do not are commonly occurring native species.

• (A) Accidental – a species that rarely or accidentally occurs in Tokelau
• (I) Introduced – a species introduced to Tokelau as a consequence, direct or indirect, of human actions
• (Ex) Extirpated – a species that no longer occurs here although populations may exist elsewhere

Order: Galliformes   Family: Phasianidae

The Phasianidae are a family of terrestrial birds that consist of quails, partridges, snowcocks, francolins, spurfowls, tragopans, monals, pheasants, peafowls, and jungle fowls. In general, they are plump (although they vary in size) and have broad, relatively short wings.

• Red junglefowl, Gallus gallus (I)

Order: Columbiformes   Family: Columbidae

Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere.

• Pacific imperial-pigeon, Ducula pacifica

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. Many of the species are brood parasites.

• Long-tailed koel, Eudynamys taitensis

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.

• Pacific golden-plover, Pluvialis fulva

Order: Charadriiformes   Family: Scolopacidae

Scolopacidae is a large diverse family of small to medium-sized shorebirds including the sandpipers, curlews, godwits, shanks, tattlers, woodcocks, snipes, dowitchers, and phalaropes. The majority of these species eat small invertebrates picked out of the mud or soil. Some species have highly specialised bills adapted to specific feeding strategies.

• Bristle-thighed curlew, Numenius tahitiensis
• Whimbrel, Numenius phaeopus (A)
• Bar-tailed godwit, Limosa lapponica
• Ruddy turnstone, Arenaria interpres
• Sanderling, Calidris alba
• Wandering tattler, Tringa incana

Order: Charadriiformes   Family: Laridae

Laridae is a family of seabirds consisting of gulls, terns, and skimmers. Gulls are typically grey or white, often with black markings on the head or wings. Terns are generally smaller than gulls with more pointed wings and bills, many also having forked tails which help with aerial manoeuvrability. Both species can be found inland near lakes and rivers, however gulls have adapted well to human presence and can often be found in urban centers.

• Brown noddy, Anous stolidus
• Black noddy, Anous minutus
• Blue-gray noddy, Anous cerulea (A)
• White tern, Gygis alba
• Sooty tern, Onychoprion fuscatus
• Gray-backed tern, Onychoprion lunatus
• Black-naped tern, Sterna sumatrana
• Great crested tern, Thalasseus bergii

Order: Phaethontiformes   Family: Phaethontidae

Tropicbirds are slender white birds of tropical oceans, with exceptionally long central tail feathers. Their heads and long wings have black markings.

Order: Procellariiformes   Family: Procellariidae

The procellariids are a group of medium-sized petrels, characterised by united nostrils with medium nasal septa and a long outer functional primary flight feather.

• Southern giant-petrel, Macronectes giganteus (A)

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 coloured inflatable throat pouches. They do not swim or walk and cannot take off from a flat surface. They are essentially aerial, able to stay aloft for days at a time.

• Lesser frigatebird, Fregata ariel
• Great frigatebird, Fregata minor

Order: Suliformes   Family: Sulidae
