The list of birds of Alaska includes every wild bird species recorded in the U.S. state of Alaska, based on the list published by the Alaska Checklist Committee. As of January 2022, there were 534 species on the official list.[1] Of them, 55 are considered rare, 149 are casual, and 79 are accidental, all as defined below. Another 18 and a species pair are considered unsubstantiated. One species is endemic to the state. One species has been added as a result of a split enacted in June 2021.[2] Additional accidental species have been added from other sources.
Only birds that are considered to have established, self-sustaining, wild populations in Alaska are included on this list. This means that birds that are considered probable escapees, although they may have been sighted flying free in Alaska, are not included. Species which the Checklist Committee considers to depend entirely on human feeding, such as rock pigeon, are also not included.
This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 62nd Supplement, published by the American Ornithological Society (AOS).[2] Common and scientific names are also those of the Check-list, except that the common names of families are from the Clements taxonomy because the AOS list does not include them.
The following codes and definitions (except En) are used by the Alaska Checklist Committee to annotate some species:
(R) = Rare - "Annual or possibly annual in small numbers; most such species occur at the perimeter of Alaska, in season; a few are scarce residents"
(C) = Casual - "Not annual; these species are beyond the periphery of annual range, but recur in Alaska at irregular intervals, usually in seasonal and regional patterns"
(A) = Accidental - "One or two Alaska records, or none in the last 30 years"
(U) = Unsubstantiated - "attributed to Alaska without specimen or photo substantiation"
(En) = Endemic - A species found only in Alaska (except as a vagrant elsewhere)
The family Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, bills which are flattened to a greater or lesser extent, and feathers that are excellent at shedding water due to special oils.
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.
Grebes are small to medium-large freshwater diving birds. They have lobed toes and are excellent swimmers and divers. However, they have their feet placed far back on the body, making them quite ungainly on land.
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.
Goatsuckers (nightjars) are medium-sized nocturnal birds that usually nest on the ground. They have long wings, short legs, and very short bills. Most have small feet, of little use for walking, and long pointed wings. Their soft plumage is cryptically colored to resemble bark or leaves.
The swifts are small birds which spend the majority of their lives flying. These birds have very short legs and never settle voluntarily on the ground, perching instead only on vertical surfaces. Many swifts have very long, swept-back wings which resemble a crescent or boomerang.
Rallidae is a large family of small to medium-sized birds which includes the rails, crakes, coots, and gallinules. The most typical family members occupy 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 tend to be weak fliers.
Cranes are large, long-legged, and long-necked birds. Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Most have elaborate and noisy courting displays or "dances".
Recurvirostridae is a family of large wading birds which includes the avocets and stilts. The avocets have long legs and long up-curved bills. The stilts have extremely long legs and long, thin, straight bills.
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.
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. Different lengths of legs and bills enable multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.
Pratincoles have short legs, very long pointed wings, and long forked tails. Their most unusual feature for birds classed as waders is that they typically hunt their insect prey on the wing like swallows, although they can also feed on the ground. Their short bills are an adaptation to aerial feeding.
Jaegers and skuas are in general medium to large birds, typically with gray or brown plumage, often with white markings on the wings. They have longish bills with hooked tips and webbed feet with sharp claws. They look like large dark gulls, but have a fleshy cere above the upper mandible. They are strong, acrobatic fliers.
The family Alcidae includes auks, murres, and puffins. These are short-winged birds that live on the open sea and normally only come ashore for breeding.
Laridae is a family of medium to large seabirds and includes gulls, terns, kittiwakes, and skimmers. They are typically gray or white, often with black markings on the head or wings. They have stout, longish bills and webbed feet.
Loons are aquatic birds the size of a large duck, to which they are unrelated. Their plumage is largely gray or black, and they have spear-shaped bills. Loons swim well and fly adequately, but are almost hopeless on land, because their legs are placed towards the rear of the body.
The albatrosses are amongst the largest of flying birds, and the great albatrosses from the genus Diomedea have the largest wingspans of any extant birds.
The storm-petrels are the smallest seabirds, relatives of the petrels, feeding on planktonic crustaceans and small fish picked from the surface, typically while hovering. The flight is fluttering and sometimes bat-like.
The procellariids are the main group of medium-sized "true petrels", characterized by united nostrils with medium septum and a long outer functional primary.
Frigatebirds are large seabirds usually found over tropical oceans. They are large, black, or black-and-white, with long wings and deeply forked tails. The males have colored 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.
Cormorants are medium-to-large aquatic birds, usually with mainly dark plumage and areas of colored skin on the face. The bill is long, thin, and sharply hooked. Their feet are four-toed and webbed.
Pelicans are very large water birds with a distinctive pouch under their beak. Like other birds in the order Pelecaniformes, they have four webbed toes.
The family Ardeidae contains the herons, egrets, and bitterns. Herons and egrets are medium to large wading birds with long necks and legs. Bitterns tend to be shorter necked and more secretive. Members of Ardeidae fly with their necks retracted, unlike other long-necked birds such as storks, ibises, and spoonbills.
The family Threskiornithidae includes the ibises and spoonbills. They have long, broad wings. Their bodies are elongated, the neck more so, with long legs. The bill is also long, curved downward in the ibises, straight and markedly flattened in the spoonbills.
The New World vultures are not closely related to Old World vultures, but superficially resemble them because of convergent evolution. Like the Old World vultures, they are scavengers, however, unlike Old World vultures, which find carcasses by sight, New World vultures have a good sense of smell with which they locate carcasses.
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.
Accipitridae is a family of birds of prey, which includes hawks, eagles, kites, harriers, and Old World vultures. These birds have very large powerful hooked beaks for tearing flesh from their prey, strong legs, powerful talons, and keen eyesight.
Typical 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.
This black, white and pink bird is quite unmistakable, especially in its erratic flight, which is like that of a giant butterfly. It is the only member of its family. The song is a trisyllabic oop-oop-oop, which gives rise to its English and scientific names.
Woodpeckers are small to medium-sized birds with chisel-like beaks, short legs, stiff tails, and long tongues used for capturing insects. Some species have feet with two toes pointing forward and two backward, while several species have only three toes. Many woodpeckers have the habit of tapping noisily on tree trunks with their beaks.
Falconidae is a family of diurnal birds of prey, notably the falcons and caracaras. They differ from hawks, eagles, and kites in that they kill with their beaks instead of their talons.
Tyrant flycatchers are Passerine birds which occur throughout North and South America. They superficially resemble the Old World flycatchers, but are more robust and have stronger bills. They do not have the sophisticated vocal capabilities of the songbirds. Most, but not all, are rather plain. As the name implies, most are insectivorous.
The vireos are a group of small to medium-sized passerine birds. They are typically greenish in color and resemble wood warblers apart from their heavier bills.
Shrikes are passerine birds known for their habit of catching other birds and small animals and impaling the uneaten portions of their bodies on thorns. A shrike's beak is hooked, like that of a typical bird of prey.
The family Corvidae includes crows, ravens, jays, choughs, magpies, treepies, nutcrackers, and ground jays. Corvids are above average in size among the Passeriformes, and some of the larger species show high levels of intelligence.
The Paridae are mainly small stocky woodland species with short stout bills. Some have crests. They are adaptable birds, with a mixed diet including seeds and insects.
Larks are small terrestrial birds with often extravagant songs and display flights. Most larks are fairly dull in appearance. Their food is insects and seeds.
The members of this family are usually rather large for "warblers". Most are rather plain olivaceous brown above with much yellow to beige below. They are usually found in open woodland, reedbeds, or tall grass. The family occurs mostly in southern to western Eurasia and surroundings, but also ranges far into the Pacific, with some species in Africa.
Locustellidae are a family of small insectivorous songbirds found mainly in Eurasia, Africa, and the Australian region. They are smallish birds with tails that are usually long and pointed, and tend to be drab brownish or buffy all over.
The family Hirundinidae is a group of passerines characterized by their adaptation to aerial feeding. These adaptations include a slender streamlined body, long pointed wings, and short bills with a wide gape. The feet are adapted to perching rather than walking, and the front toes are partially joined at the base.
Leaf warblers are a family of small insectivorous birds found mostly in Eurasia and ranging into Wallacea and Africa. The Arctic warbler breeds east into Alaska. The species are of various sizes, often green-plumaged above and yellow below, or more subdued with grayish-green to grayish-brown colors.
The family Sylviidae is a group of small insectivorous passerine birds. They 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.
The kinglets are a small family of birds which resemble the titmice. They are very small insectivorous birds. The adults have colored crowns, giving rise to their names.
The waxwings are a group of birds with soft silky plumage and unique red tips to some of the wing feathers. In the Bohemian and cedar waxwings, these tips look like sealing wax and give the group its name. These are arboreal birds of northern forests. They live on insects in summer and berries in winter.
Nuthatches are small woodland birds. They have the unusual ability to climb down trees head first, unlike other birds which can only go upwards. Nuthatches have big heads, short tails, and powerful bills and feet.
Treecreepers are small woodland birds, brown above and white below. They have thin pointed down-curved bills, which they use to extricate insects from bark. They have stiff tail feathers, like woodpeckers, which they use to support themselves on vertical trees.
Wrens are small and inconspicuous birds, except for their loud songs. They have short wings and thin down-turned bills. Several species often hold their tails upright.
The mimids are a family of passerine birds which includes thrashers, mockingbirds, tremblers, and the New World catbirds. These birds are notable for their vocalization, especially their remarkable ability to mimic a wide variety of birds and other sounds heard outdoors. The species tend towards dull grays and browns in their appearance.
Starlings are small to medium-sized passerine birds. They are medium-sized passerines with strong feet. Their flight is strong and direct and they are very gregarious. Their preferred habitat is fairly open country, and they eat insects and fruit. Plumage is typically dark with a metallic sheen.
The thrushes are a group of passerine birds that occur mainly but not exclusively 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.
This a large family of small passerine birds restricted to the Old World. Most of the species below only occur in North America as vagrants. The appearance of these birds is highly varied, but they mostly have weak songs and harsh calls.
The accentors are small, fairly drab birds with thin sharp bills superficially similar, but unrelated to, sparrows. They are endemic to the Palearctic and only appear in North America as a vagrant.
Old World sparrows are small passerine birds. In general, sparrows tend to be small plump brownish or grayish birds with short tails and short powerful beaks. Sparrows are seed eaters, but they also consume small insects.
House sparrow, Passer domesticus (C) (Introduced to North America)
Motacillidae is a family of small passerine birds with medium to long tails. They include the wagtails, longclaws, and pipits. They are slender ground-feeding insectivores of open country.
Finches are seed-eating passerine birds, that are small to moderately large and have a strong beak, usually conical and in some species very large. All have twelve tail feathers and nine primaries. These birds have a bouncing flight with alternating bouts of flapping and gliding on closed wings, and most sing well.
The Calcariidae are a group of passerine birds that had been traditionally grouped with the New World sparrows, but differ in a number of respects and are usually found in open grassy areas.
Emberizidae is a family of passerine birds containing a single genus. Until 2017, the New World sparrows (Passerellidae) were also considered part of this family.
Until 2017, these species were considered part of the family Emberizidae. Most of the species are known as sparrows, but these birds are not closely related to the Old World sparrows which are in the family Passeridae. Many of these have distinctive head patterns.
The icterids are a group of small to medium-sized, often colorful passerine birds restricted to the New World and include the grackles, New World blackbirds, and New World orioles. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red.
The wood-warblers are a group of small often colorful passerine birds restricted to the New World. Most are arboreal, but some like the ovenbird and the two waterthrushes are more terrestrial. Most members of this family are insectivores.
The cardinals are a family of robust seed-eating birds with strong bills. They are typically associated with open woodland. The sexes usually have distinct plumages.
