Tokelau is a dependent territory of New Zealand in Polynesia in the Pacific Ocean, comprising three coral atolls with a total land area of 10.1km2 (3.9sqmi).[1] There are 33 species of birds that have been recorded from Tokelau, of which one has been introduced by humans. Additionally, Anas ducks are also seasonal visitors to the islands.[2] 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.[2] Three species of birds found in Tokelau, the bristle-thighed curlew, bar-tailed godwit, and flesh-footed shearwater, are near-threatened.[3][4][5] One of the 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.[1]
The black noddy is one of the most common birds in Tokelau.
Tokelau has a moist tropical climate year-round, with an average temperature of 28°C (82°F) and a mean annual rainfall of over 3,000mm (120in). 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, with other tropical trees like Cordia subcordata, Pisonia grandis, Guettarda speciosa, and Pandanus also being present. 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.[6]
This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of the 2021 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: CharadriiformesFamily: 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.[12]

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.[15]
