This is a list of the bird species recorded on Inaccessible Island. The avifauna of Inaccessible Island include a total of 51 species.

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, 2022 edition. 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 Inaccessible Island.

The following tags have been used to highlight several categories. The commonly occurring native species do not fall into any of these categories.


 * (A) Accidental - a species that rarely or accidentally occurs on Inaccessible Island.
 * (E) Endemic - a species endemic to Inaccessible Island.

Rails, gallinules, and coots
Order: GruiformesFamily: 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.


 * Inaccessible Island rail, Atlantisia rogersi (E)
 * Purple gallinule, Porphyrio martinica (A)

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.


 * White-rumped sandpiper, Calidris fuscicollis (A)

Skuas and jaegers
Order: CharadriiformesFamily: 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.


 * Chilean skua, Stercorarius chilensis (A)
 * Brown skua, Stercorarius antarcticus
 * Parasitic jaeger, Stercorarius parasiticus (A)
 * Long-tailed jaeger, Stercorarius longicaudus (A)

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.


 * Kelp gull, Larus dominicanus (A)
 * Brown noddy, Anous stolidus
 * Arctic tern, Sterna paradisaea (A)
 * Antarctic tern, Sterna vittata

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.


 * Red-tailed tropicbird, Phaethon rubricauda (A)

Penguins
Order: SphenisciformesFamily: Spheniscidae

The penguins are a group of flightless aquatic birds living almost exclusively in the Southern Hemisphere. Most penguins feed on krill, fish, squid, and other forms of marine life caught while swimming underwater.


 * Macaroni penguin, Eudyptes chrysolophus (A)
 * Moseley's rockhopper penguin, Eudyptes moseleyi

Albatrosses
Order: ProcellariiformesFamily: Diomedeidae

The albatrosses are among the largest of flying birds, and the great albatrosses from the genus Diomedea have the largest wingspans of any extant birds.


 * Yellow-nosed albatross, Thalassarche chlororhynchos
 * Gray-headed albatross, Thalassarche chrysostoma
 * White-capped albatross, Thalassarche cauta
 * Black-browed albatross, Thalassarche melanophris
 * Sooty albatross, Phoebetria fusca
 * Light-mantled albatross, Phoebetria palpebrata
 * Wandering albatross, Diomedea exulans

Southern storm-petrels
Order: ProcellariiformesFamily: Oceanitidae

The southern storm-petrels are relatives of the petrels and are the smallest seabirds. They feed on planktonic crustaceans and small fish picked from the surface, typically while hovering. The flight is fluttering and sometimes bat-like.


 * Wilson's storm-petrel, Oceanites oceanicus
 * Gray-backed storm-petrel, Garrodia nereis (A)
 * White-faced storm-petrel, Pelagodroma marina
 * White-bellied storm-petrel, Fregetta grallaria
 * Black-bellied storm-petrel, Fregetta tropica

Northern storm-petrels
Order: ProcellariiformesFamily: 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.


 * Leach's storm-petrel, Hydrobates leucorhous

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.

Swallows
Order: PasseriformesFamily: Hirundinidae

Thrushes and allies
Order: PasseriformesFamily: Turdidae

The thrushes are a group of passerine birds that occur mainly in the Old World. They are plump, soft plumaged, small to medium-sized insectivores or sometimes omnivores, often feeding on the ground. Many have attractive songs.


 * Tristan thrush, Turdus eremita

Tanagers
Order: PasseriformesFamily: Thraupidae

The tanagers are a large group of small to medium-sized passerine birds restricted to the New World, mainly in the tropics. Many species are brightly colored. As a family they are omnivorous, but individual species specialize in eating fruits, seeds, insects, or other types of food. Most have short, rounded wings.
