This is a list of the bird species recorded in Nauru. The avifauna of Nauru includes a total of 27 species, of which 1 is endemic.
This list's taxonomic treatment (designation and sequence of orders, families, and species) and nomenclature (common and scientific names) follow the conventions of Clements's 5th edition. The family accounts at the beginning of each heading reflects this taxonomy, as do the species counts found in each family account.
The following tags have been used to highlight certain relevant categories. Not all species fall into one of these categories. Those that do not are commonly occurring, native species.

Order: Procellariiformes Family: Procellariidae
The procellariids are the main group of medium-sized 'true petrels', characterised by united nostrils with a medium septum, and a long outer functional primary. There are 75 species worldwide and 1 species which occurs in Nauru.
Order: Pelecaniformes Family: Phaethontidae
Tropicbirds are slender white birds of tropical oceans, with exceptionally long central tail feathers. Their heads and long wings have black markings. There are 3 species worldwide and 2 species which occur in Nauru.
Order: Pelecaniformes Family: Sulidae
The sulids comprise the gannets and boobies. Both groups comprise medium-to-large coastal sea-birds that plunge-dive for fish. There are 9 species worldwide and 1 species which occurs in Nauru.
Order: Pelecaniformes Family: Fregatidae
Frigatebirds are large sea-birds usually found over tropical oceans. They are large, black and white or completely black, with long wings and deeply-forked tails. The males have inflatable coloured 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. There are 5 species worldwide and 1 species which occurs in Nauru.
Order: Ciconiiformes Family: Ardeidae
The family Ardeidae contains the bitterns, herons and egrets. Herons and egrets are medium to large sized wading birds with long necks and legs. Bitterns tend to be shorter necked and more wary. Unlike other long-necked birds such as storks, ibises and spoonbills, members of Ardeidae fly with their necks retracted. There are 61 species worldwide and 1 species which occurs in Nauru.
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, although there are some exceptions. There are 66 species worldwide and 4 species which occur in Nauru.
Order: Charadriiformes Family: Scolopacidae
The Scolopacidae are 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 species eat small invertebrates picked out of the mud or soil. Variation in length of legs and bills enable different species to feed in the same habitat, particularly on the coast, without direct competition for food. There are 89 species worldwide and 7 species which occur in Nauru.
Order: Charadriiformes Family: Sternidae
Terns are a group of generally general medium to large sea-birds 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 now known to live in excess of 25 to 30 years. There are 44 species worldwide and 5 species which occur in Nauru.
Order: Columbiformes Family: Columbidae
Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere. There are 308 species worldwide and 1 species which occurs in Nauru.
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. Unlike the cuckoo species of the Old World, North American cuckoos are not brood parasites. There are 138 species worldwide and 1 species which occurs in Nauru.
Order: Coraciiformes Family: Alcedinidae
Kingfishers are medium-sized birds with large heads, long pointed bills, short legs, and stubby tails. There are 93 species worldwide and 2 species which occur in Nauru.
Order: Passeriformes Family: Sylviidae
The family Sylviidae is a group of small insectivorous passerine birds. The Sylviidae mainly occur as breeding species, as the common name implies, in Europe, Asia and, to a lesser extent Africa. Most are of generally undistinguished appearance, but many have distinctive songs. There are 291 species worldwide and 1 species which occurs in Nauru.
