# List of birds of Maine

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

## Pheasants, grouse, and allies

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. 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.

## Hummingbirds

Order: Apodiformes Family: Trochilidae
