List of birds of the Galápagos Islands
This list of birds recorded in the Galápagos Islands includes species documents from the Galápagos Islands of Ecuador, where 185 species have been documented as of February 2019. Of them, 31 are endemic, three nest only in the Galápagos, and virtually the entire population of a fourth nests there. Seventeen endemic subspecies are noted. In addition, 85 of the species are accidental, five were introduced to the islands, and five are domesticated. Unless otherwise noted, this list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific  names) are those of the South American Classification Committee (SACC) of the American Ornithological Society. The following tags are used to define several categories of occurrence. Untagged species are common non-endemic residents, migrants, or seasonal visitors. Ducks. Order: Anseriformes Family: Anatidae These are adapted to an aquatic life, possessing webbed feet, an oily covering on their feathers to shed water, and bills adapted to their feeding needs. Guineafowl. Order Galliformes Family Numididae Guineafowl are African gamebirds, mostly spotted, with bare skin on the head and neck to lose heat. Pheasants. Order Galliformes Family Phasianidae Phasianidae consists of the pheasants  and their allies. These are terrestrial species, variable in size but generally plump with broad relatively short wings. Many species are gamebirds or have been domesticated as a food source for humans. Flamingos. Order Phoenicopteriformes Family Phoenicopteridae Flamingos are water birds with a downcurved beak for sieving food. Grebes. Order Podicipediformes Family Podicipedidae Grebes are aquatic birds most closely related to flamingoes. They are well adapted to living in water but are clumsy on land, never straying far from water when they build their nests. Pigeons. Order Columbiformes Family Columbidae Pigeons and doves are medium to large mostly plump birds . Most are arboreal species descending to the ground to feed but some are terrestrial like the quail-doves of South America or the pheasant-pigeon of New Guinea. They are found worldwide except near the poles and in a wide variety of habitats including urban. The feral form of the rock pigeon has been introduced worldwide. Cuckoos. Order Cuculiformes Family Cuculidae Cuckoos are found almost worldwide. They are highly variable in size, shape, colour, and habits. Nightjars. Order Caprimulgiformes Family Caprimulgidae Nighthawks belong to the same family as nightjars but are found only in the Americas. They have mottled or  striped plumage for camouflage. Swifts. Order Apodiformes Family Apodidae Swifts are aerodynamic species which are found worldwide. Some species are migratory, others resident, and others still have both migratory and resident populations. Rails. Order Gruiformes Family Rallidae Rails are usually secretive birds. Many island species are flightless and many of those have gone extinct in the last five centuries. Gallinules are less secretive, and are usually found near or on water. Plovers. Order Charadriiformes Family Charadriidae Plovers are dull-coloured shorebirds without many distinguishing features. The bill is short and straight to catch worms on the surface. Lapwings are slightly  bigger and more colourful shorebirds. Their legs are longer than plover's but the bill is the same size with respect to the body. Oystercatchers. Order Charadriiformes Family Haematopodidae Oystercatchers are black or black and white shorebirds with long orange bills and with or without an eyering. The legs are pinkish. Avocets. Order Charadriiformes Family Recurvirostridae Stilts are spindly legged birds with black and white markings. Sandpipers. Order Charadriiformes Family Scolopacidae Sandpipers are long-legged mostly long-billed shorebirds. Some like woodcocks and snipes are forest species but most others are estuarine or wetland species. Skuas. Order Charadriiformes Family Stercorariidae  Stercorariidae are predatory birds typically separated into the bigger "Catharacta" skuas and the smaller "Stercorarius" jaegers. Gulls. Order Charadriiformes Family Laridae Gulls are seabirds although some are found on freshwater. They have hooked bills and some have hoods or caps on their heads. Terns were formerly placed in a family of their own, Sternidae, but now they are commonly placed along with gulls and skimmers in Laridae. Their bills are straighter than those of gulls. Tropicbirds. Order Phaethontiformes Family Phaethontidae Tropicbirds are seabirds once thought to be closely related to pelicans but are now known to belong to a clade  known as Metaves. Penguins. Order Sphenisciformes Family Spheniscidae Penguins are southern ocean birds with only this one species occurring north of the equator. They are small to large in size and mostly black and white in colour. Albatrosses. Order Procellariiformes Family Diomedeidae Albatrosses are large tubenoses with wingspans of more than a meter. Most are southern ocean species but some are found in the northern Pacific Ocean. Southern storm-petrels. Order: Procellariiformes Family: Oceanitidae Storm-petrels are small marine birds that are mostly black and white. Until 2018, this family's species were included with the other storm-petrels in  family Hydrobatidae. Northern storm-petrels. Order: Procellariiformes Family: 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. Shearwaters. Order Procellariiformes Family Procellariidae Petrels and shearwaters are known collectively as tubenoses for the tubes on their beaks which they use for excreting salt. Frigatebirds. Order Suliformes Family Fregatidae Frigatebirds are black (with some white markings) seabirds. The males have a red throat patch to attract females. Boobies. Order Suliformes Family Sulidae Boobies are seabirds  which were once lumped along with darters, cormorants, and frigatebirds in Pelecaniformes. Their feet are variously coloured, black with striped toes in gannets, and grey, red, blue, yellow, black, or ochre in boobies. Cormorants. Order Suliformes Family Phalacrocoracidae Cormorants are seabirds which normally stand upright. Most of them have markings on their face and wings. Only the Galápagos species is flightless. Pelicans. Order Pelecaniformes Family Pelecanidae Pelicans are large seabirds, variable in colour but alike in shape. All have a gular pouch to catch fish. Herons. Order Pelecaniformes Family Ardeidae Herons are long-necked long-legged water birds. The majority  feed on fish and other pond-life. Osprey. Order Accipitriformes Family Pandionidae Pandionidae is a monotypic family of fish-eating birds of prey. Its single species possesses a very large and powerful hooked beak, strong legs, strong talons, and keen eyesight. Hawks. Order Accipitriformes Family Accipitridae Hawks are close relatives of eagles and kites although none of these have been recorded in the Galápagos. Barn owls. Order Strigiformes Family Tytonidae Barn owls are owls with a heart-shaped face. Owls. Order Strigiformes Family Strigidae Typical or "true" owls are small to large solitary nocturnal birds of prey. They have large  forward-facing eyes and ears, a hawk-like beak, and a conspicuous circle of feathers around each eye called a facial disk. Kingfishers. Order Coraciiformes Family Alcedinidae Kingfishers are medium-sized birds with large heads, long, pointed bills, short legs, and stubby tails. Falcons. Order Falconiformes Family Falconidae Falcons are streamlined aerodynamic birds of prey which were traditionally thought to be closely related to the Accipitriformes. Recent genetic studies place them closer to parrots. New World and African parrots. Order Psittaciformes Family Psittacidae Parrots are colourful tropical species with a curved bill and zygodactyl feet. Tyrant flycatchers. Order Passeriformes Family  Tyrannidae Tyrant flycatchers are a group of American passerines which are not related to the Old World flycatchers of the family Muscicapidae. Vireos. Order Passeriformes Family Vireonidae Vireos are small greenish or yellowish birds. Swallows. Order Passeriformes Family Hirundinidae Swallows and martins are passerines not closely related to swifts although they have superficial resemblance. They have short pointed wings. Waxwings. Order Passeriformes Family Bombycillidae Waxwings are medium-sized, plump birds. All three species in the family are migratory and occasionally turn up in unexpected places. Mockingbirds. Order Passeriformes Family Mimidae Mockingbirds are an American group of passerine birds. In the  Galápagos they are famous (along with Darwin's finches) for confirming Charles Darwin's theory of evolution. Blackbirds. Order Passeriformes Family Icteridae The icterids are a group of small to medium-sized, often colourful passerine birds restricted to the New World. Wood-warblers. Order Passeriformes Family Parulidae The wood-warblers are a group of small, often colorful, passerine birds restricted to the New World. Most are arboreal, but some are more terrestrial. Most members of this family are insectivores. Cardinals. Order Passeriformes Family Cardinalidae Cardinals are a group of finch-like birds; most are colourful with seed-eating beaks. Tanagers . Order Passeriformes Family Thraupidae The tanagers are a large group of small to medium-sized passerine birds restricted to the New World, mainly in the tropics. Most of the 19 species in the family which have been recorded in the Galápagos are "Darwin's finches". Famous for inspiring Darwin in his theory of evolution, the finches have astonishingly different beaks.
