List of birds of Nauru

This is a list of the bird species recorded in Nauru. The avifauna of Nauru include a total of twenty-seven species, of which one 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 "The Clements Checklist of Birds of the World", 6th edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account.
The following tag has been used to highlight endemic species. The commonly occurring native species are untagged.
Pheasants, grouse, and allies.
Order: GalliformesFamily: Phasianidae
The Phasianidae are a family of terrestrial birds which consists of quails, partridges, snowcocks, francolins, spurfowls, tragopans, monals, pheasants, peafowls, grouse, ptarmigan, and junglefowls. In general, they are plump (although they vary in size) and have broad, relatively short wings.
Shearwaters and petrels.
Order: ProcellariiformesFamily: Procellariidae
The procellariids are the main group of medium-sized "true petrels", characterised by united nostrils with medium septum and a long outer functional primary.
Tropicbirds.
Order: PelecaniformesFamily: Phaethontidae
Tropicbirds are slender white birds of tropical oceans, with exceptionally long central tail feathers. Their heads and long wings have black markings.
Boobies and gannets.
Order: SuliformesFamily: Sulidae
The sulids comprise the gannets and boobies. Both groups are medium to large coastal seabirds that plunge-dive for fish.
Frigatebirds.
Order: SuliformesFamily: 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 coloured 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.
Herons, egrets, and bitterns.
Order: PelecaniformesFamily: 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.
Plovers and lapwings.
Order: CharadriiformesFamily: 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.
Sandpipers and allies.
Order: CharadriiformesFamily: 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. Variation in length of legs and bills enables multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.
Gulls, terns, and skimmers.
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. Terns are generally long-lived birds, with several species known to live in excess of 30 years.
Pigeons and doves.
Order: ColumbiformesFamily: Columbidae
Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere.
Cuckoos and anis.
Order: CuculiformesFamily: 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.
Kingfishers.
Order: CoraciiformesFamily: Alcedinidae
Kingfishers are medium-sized birds with large heads, long pointed bills, short legs and stubby tails.
Acrocephalid warblers.
Order: PasseriformesFamily: Acrocephalidae
The family Acrocephalidae is a group of small insectivorous passerine birds. Most are of generally undistinguished appearance, but many have distinctive songs.
