This list of birds of New Hampshire includes species documented in the U.S. state of New Hampshire and accepted by New Hampshire Rare Bird Committee (NHRBC) and New Hampshire Audubon (NHA). As of February 2021, the list contained 425 species. Of them, 136 are on the review list (see below) and six have been introduced to North America. Three are extinct and three have been extirpated. To this list are added seven hypothetical species, defined below; they are also tagged (R). Three additional accidental species have been added from other sources.

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, the species listed below are considered to occur regularly in New Hampshire as permanent residents, summer or winter visitors, or migrants. The following codes are used to denote other categories of occurrence:

(I) Introduced - a species introduced to North America by the actions of humans (E) Extinct - a recent species that no longer exists (Ex) Extirpated - a species formerly present in New Hampshire which still exists elsewhere (R) Review list - birds that if seen require more comprehensive documentation than regularly seen species. These birds are considered irregular or rare in New Hampshire. (H) Hypothetical - "modern records which are likely accurate, but do not meet the current criteria for a first state record" per the NHRBC

Ducks, geese, and waterfowl Order: AnseriformesFamily: Anatidae

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.

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 New Hampshire.

Northern bobwhite, Colinus virginianus (Ex)

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. In all New Hampshire species, 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. Four species have been recorded in New Hampshire.

Wild turkey, Meleagris gallopavo Ruffed grouse, Bonasa umbellus Spruce grouse, Canachites canadensis Ring-necked pheasant, Phasianus colchicus (I)

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. Five species have been recorded in New Hampshire.

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

Common cuckoo, Cuculus canorus (accidental) 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 New Hampshire.

Common nighthawk, Chordeiles minor Chuck-will's-widow, Antrostomus carolinensis (R) Eastern whip-poor-will, Antrostomus vociferus

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 New Hampshire.

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 New Hampshire.

Ruby-throated hummingbird, Archilochus colubris Anna's hummingbird, Calypte anna (R) Rufous hummingbird, Selasphorus rufus (R) Calliope hummingbird, Selasphorus calliope (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 New Hampshire.

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 martinica (R) Yellow rail, Coturnicops noveboracensis (R) Black rail, Laterallus jamaicensis (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 New Hampshire.

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 New Hampshire.

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-four species have been recorded in New Hampshire.
