This list of birds of Maine is a comprehensive listing of all the bird species recorded in the U.S. state of Maine. This list is published by the Maine Bird Records Committee (MBRC) and is dated December 2022.

This list contains 470 documented species, of which 141 are rare or accidental, five have been introduced and are established, and three are extinct. Two species were introduced but did not become established, two are regularly released, and ten are hypothetical as defined below. These 14 are not included in the 470 documented species. Additional rare species have been added from another source.

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). 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.

Unless otherwise noted, all species listed below are considered to occur regularly in Maine as permanent residents, summer or winter visitors, or migrants. The following tags are used to designate some species:

(R) Rare or accidental - birds that if seen require more comprehensive documentation than regularly seen species. These birds are considered rare or accidental in Maine. (I) Introduced - a species introduced to North America by the actions of humans, either directly or indirectly (E) Extinct - a recent species that no longer exists (H) Hypothetical - species whose records "lack physical documentation, whether by specimen, photograph, or recording, or involve descriptions that are only partially adequate" per the MBRC (FI) Failed introduced - species that "bred for some years in Maine but never became established" per the MBRC (NE) Not established - species "routinely released or escaped ... not established or known to be natural vagrants" per the MBRC

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. Forty-seven species have been recorded in Maine.

New World quail Order: GalliformesFamily: Odontophoridae

The New World quails are small, plump terrestrial birds only distantly related to the quails of the Old World, but named for their similar appearance and habits. One species has been recorded in Maine.

Northern bobwhite, Colinus virginianus (NE)

Pheasants, grouse, and allies Order: GalliformesFamily: 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. Turkeys have a distinctive fleshy wattle that hangs from the underside of the beak and a fleshy protuberance that hangs from the top of its beak called a snood. As with many galliform species, the female (the hen) is smaller than the male (the tom) and much less colorful. With wingspans of 1.5–1.8 meters (almost 6 feet), the turkeys are the largest birds in the open forests in which they live and are rarely mistaken for any other species. Grouse inhabit temperate and subarctic regions of the Northern Hemisphere. They are game and are sometimes hunted for food. Males are polygamous and have elaborate courtship displays. These heavily built birds have legs feathered to the toes. Most species are year-round residents and do not migrate. Eight species have been recorded in Maine.

Wild turkey, Meleagris gallopavo (extirpated, reintroduced) Ruffed grouse, Bonasa umbellus Spruce grouse, Canachites canadensis Willow ptarmigan, Lagopus lagopus (R) Greater prairie-chicken, Tympanuchus cupido (H) Gray partridge, Perdix perdix (FI) Ring-necked pheasant, Phasianus colchicus (I) Chukar, Alectoris chukar (NE)

Grebes Order: PodicipediformesFamily: Podicipedidae

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. Six species have been recorded in Maine.

Pied-billed grebe, Podilymbus podiceps Horned grebe, Podiceps auritus Red-necked grebe, Podiceps grisegena Eared grebe, Podiceps nigricollis (R) Western grebe, Aechmorphorus occidentalis (R) Clark's grebe, Aechmorphorus clarkii (R)

Yellow-billed cuckoo, Coccyzus americanus Black-billed cuckoo, Coccyzus erythropthalmus

Nightjars and allies Order: CaprimulgiformesFamily: Caprimulgidae

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. Three species have been recorded in Maine.

Swifts Order: ApodiformesFamily: Apodidae

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 long swept-back wings which resemble a crescent or boomerang. One species has been recorded in Maine.

Chimney swift, Chaetura pelagica

Hummingbirds

Order: ApodiformesFamily: Trochilidae

Hummingbirds are small birds capable of hovering in mid-air due to the rapid flapping of their wings. They are the only birds that can fly backwards. Four species have been recorded in Maine.

Mexican violetear, Colibri thalassinus (R) Ruby-throated hummingbird, Archilochus colubris Calliope hummingbird, Selasphorus calliope (R) Rufous hummingbird, Selasphorus rufus (R) Broad-tailed hummingbird, Selasphorus platycercus (R)

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. 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 to be weak fliers. Nine species have been recorded in Maine.

Clapper rail, Rallus crepitans (R) King rail, Rallus elegans (R) Virginia rail, Rallus limicola Sora, Porzana carolina Common gallinule, Gallinula galeata American coot, Fulica americana Purple gallinule, Porphyrio martinicus Yellow rail, Coturnicops noveboracensis (R) Corn crake, Crex crex (R)

Cranes Order: GruiformesFamily: Gruidae

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". One species has been recorded in Maine.

Sandhill crane, Antigone canadensis

Stilts and avocets Order: CharadriiformesFamily: Recurvirostridae

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. Two species have been recorded in Maine.

Black-necked stilt, Himantopus mexicanus (R) American avocet, Recurvirostra americana

Oystercatchers Order: CharadriiformesFamily: Haematopodidae

American oystercatcher, Haematopus palliatus

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. Eleven species have been recorded in Maine.

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. Thirty-eight species have been recorded in Maine.
