This list of birds of Montana includes species documented in the U.S. stateofMontana and accepted by the Montana Bird Records Committee (MBRC). As of July 2021, there are 442 species included in the official list. Of them, 104 are on the review list (see below) and eight have been introduced to North America.[1] An additional 10 species are on a separate supplemental list.[2]
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).[3] 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 Montana as permanent residents, summer or winter visitors, or migrants. These tags are used to annotate some species:
Order: Anseriformes Family: 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. Forty-two species have been recorded in Montana.
Order: Galliformes Family: Odontophoridae

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. Twelve species have been recorded in Montana.
Order: Podicipediformes Family: 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 Montana.

Order: Caprimulgiformes Family: 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 Montana.
Order: Apodiformes Family: Apodidae

Many swifts have very long, swept-back wings which resemble a crescent or boomerang. Four species have been recorded in Montana.
Order: Apodiformes Family: 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. Eight species have been recorded in Montana.

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. Five species have been recorded in Montana.
Order: Gruiformes Family: Gruidae

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-five species have been recorded in Montana.
Order: Charadriiformes Family: Stercorariidae
Skuas and jaegers are in general medium to large birds, typically with gray or brown plumage, often with white markings on the wings.

Order: Suliformes Family: Phalacrocoracidae
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. Two species have been recorded in Montana.
