This is a list of bird species confirmed in the Canadian territory of Northwest Territories. Unless otherwise noted, the list is that of Bird Checklists of the World as of March 2021. Of the 296 species on the list, 61 are accidental and four were introduced to North America. One species is extinct and another probably is.
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 Canadian English spellings are used and the common names of families are from the Clements taxonomy because the AOS list does not include them.
The following tags are used to categorise some species:
(A) Accidental - a species that rarely or accidentally occurs in Northwest Territories (I) Introduced - a species introduced to Northwest Territories as a consequence, direct or indirect, of human actions
Ducks, geese, and waterfowl Order: AnseriformesFamily: Anatidae
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.

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.
Pied-billed grebe, Podilymbus podiceps Horned grebe, Podiceps auritus Red-necked grebe, Podiceps grisegena Eared grebe, Podiceps nigricollis
Pigeons and doves Order: ColumbiformesFamily: Columbidae
Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere. They feed on seeds, fruit and plants. Unlike most other birds, the doves and pigeons produce "crop milk," which is secreted by a sloughing of fluid-filled cells from the lining of the crop. Both sexes produce this highly nutritious substance to feed to the young.

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 coloured to resemble bark or leaves.
Common nighthawk, Chordeiles minor
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.

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.
Sora, Porzana carolina American coot, Fulica americana Yellow rail, Coturnicops noveboracensis
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".
Sandhill crane, Antigone canadensis Whooping crane, Grus americana
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.

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.

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.

Skuas and jaegers are in general medium to large birds, typically with grey 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.

Auks, murres, and puffins Order: CharadriiformesFamily: Alcidae
Alcids are superficially similar to penguins due to their black-and-white colours, their upright posture, and some of their habits, however they are only distantly related to the penguins and are able to fly. Auks live on the open sea, only deliberately coming ashore to nest.

Loons Order: GaviiformesFamily: Gaviidae
Loons are aquatic birds, the size of a large duck, to which they are unrelated. Their plumage is largely grey 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.
