The Canada jay has been proposed as the national bird of Canada.[1]

This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 61st Supplement, published by the American Ornithological Society (AOS).[3] 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.

Canadian birds most closely resemble those of Eurasia, which was connected to the continent as part of the supercontinent Laurasia until around 60 million years ago.[4] Many families which occur in Canada are also found throughout the Northern Hemisphere or worldwide. However, some families are unique to the New World; those represented in this list are the hummingbirds, the New World vultures, the New World quail, the tyrant flycatchers, the mimids, the wood-warblers, the cardinals, and the icterids.[5] Three species on the list (Ross's goose, whooping crane, and Harris's sparrow) breed only in Canada.[3] The extinct Labrador duck is also believed to have been a breeding endemic, though this is disputed.[6][7][8]

Unless otherwise noted, all species listed below are considered to occur regularly in Canada as permanent residents, summer or winter visitors, or migrants. These tags are used to annotate some species:

  • (A) Accidental - a species that rarely or accidentally occurs in Canada
  • (I) Introduced - a species introduced to Canada as a consequence, direct or indirect, of human actions
  • (E) Extinct - a recent species which no longer exists
  • (Ex) Extirpated - a species which not longer occurs in Canada but exists elsewhere

Population status symbols are those of the Red List published by the International Union for Conservation of Nature (IUCN).[9] The symbols apply to the species' worldwide status, not their status solely in Canada. The symbols and their meanings, in increasing order of peril, are:

LC = least concern NT = near threatened VU = vulnerable EN = endangered CR = critically endangered EW = extinct in the wild EX = extinct


Ducks, geese, and waterfowl
Trumpeter swan
Wood duck pair
Common eider

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.

New World quail
California quail

Order: Galliformes   Family: 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.

Pheasants, grouse, and allies
Wild turkey

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.

Flamingos

Order: Phoenicopteriformes   Family: Phoenicopteridae

Flamingos (genus Phoenicopterus monotypic in family Phoenicopteridae) are gregarious wading birds, usually 3 to 5 feet (0.9 to 1.5 m) tall, found in both the Western and Eastern Hemispheres. Flamingos filter-feed on shellfish and algae. Their oddly shaped beaks are specially adapted to separate mud and silt from the food they consume and, uniquely, are used upside-down.

Grebes
Clark's grebe

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.

Pigeons and doves

Order: Columbiformes   Family: Columbidae

Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere.

Cuckoos
Black-billed cuckoo

Order: Cuculiformes   Family: Cuculidae

The family Cuculidae includes cuckoos, roadrunners, and anis. These birds are of variable size with slender bodies, long tails, and strong legs.

Nightjars and allies

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 coloured to resemble bark or leaves.

Swifts

Order: Apodiformes   Family: 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.

Hummingbirds
Ruby-throated hummingbird

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.

Rails, gallinules, and coots
King rail

Order: Gruiformes   Family: Rallidae

Rallidae is a large family of small to medium-sized birds which includes the rails, crakes, coots, and gallinules. Typically, family members occupy dense vegetation in damp environments near lakes, swamps, and 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 flyers.

Limpkin
Limpkin

Order: Gruiformes   Family: Aramidae

The limpkin is an odd bird that looks like a large rail, but is skeletally closer to the cranes. It is found in marshes with some trees or scrub in the Caribbean, South America, and southern Florida.

Cranes

Order: Gruiformes   Family: Gruidae

Cranes are large, long-legged, and long-necked birds. Unlike the similar-looking, but unrelated, herons, cranes fly with their necks outstretched, not pulled back. Most have elaborate and noisy courting displays.

Stilts and avocets
American avocet

Order: Charadriiformes   Family: 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.

Oystercatchers

Order: Charadriiformes   Family: Haematopodidae

The oystercatchers are large, obvious and noisy plover-like birds, with strong bills used for smashing or prying open molluscs.

Plovers and lapwings
Killdeer

Order: Charadriiformes   Family: 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.

Sandpipers and allies
Greater yellowlegs
Red-necked phalarope

Order: Charadriiformes   Family: Scolopacidae

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 directly competing for food.

Skuas and jaegers

Order: Charadriiformes   Family: Stercorariidae

Skuas 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
Pigeon guillemot

Order: Charadriiformes   Family: 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.

Gulls, terns, and skimmers

Ring-billed gull

Order: Charadriiformes   Family: Laridae

Laridae is a family of medium to large seabirds and includes gulls, terns, and skimmers. Gulls are typically grey or white, often with black markings on the head or wings. They have stout, longish bills, and webbed feet. Terns are a group of generally medium to large seabirds typically with grey or white plumage, often with black markings on the head. Most terns hunt fish by diving but some pick insects off the surface of fresh water. Terns are generally long-lived birds, with several species known to live in excess of 30 years. Skimmers are a small family of tropical tern-like birds. They have an elongated lower mandible which they use to feed by flying low over the water surface and skimming the water for small fish.

Tropicbirds

Order: Phaethontiformes   Family: Phaethontidae

Tropicbirds are slender white birds of tropical oceans with exceptionally long central tail feathers. Their long wings have black markings, as does the head.

Loons
Pacific loon

Order: Gaviiformes   Family: 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, because their legs are placed towards the rear of the body, are almost helpless on land.

Albatrosses

Order: Procellariiformes   Family: Diomedeidae

The albatrosses are amongst the largest of flying birds, and the great albatrosses from the genus Diomedea have the largest wingspans of any extant birds.

Southern storm-petrels
Wilson's storm-petrel

Order: Procellariiformes   Family: Oceanitidae

The storm-petrels are the smallest seabirds, relatives of the petrels, feeding on planktonic crustaceans and small fish picked from the surface, typically while hovering. The flight is fluttering and sometimes bat-like. Until 2018, this family's three species were included with the other storm-petrels in family Hydrobatidae.

Northern storm-petrels

Order: Procellariiformes   Family: Hydrobatidae

Though the members of this family are similar in many respects to the southern storm-petrels, including their general appearance and habits, there are enough genetic differences to warrant their placement in a separate family.

Shearwaters and petrels
Northern fulmar

Order: Procellariiformes   Family: Procellariidae

The procellariids are the main group of medium-sized "true petrels", characterized by united nostrils with medium septum and a long outer functional primary.

Storks

Order: Ciconiiformes   Family: Ciconiidae

Storks are large, heavy, long-legged, long-necked wading birds with long stout bills and wide wingspans. They lack the powder down that other wading birds such as herons, spoonbills and ibises use to clean off fish slime. Storks lack a pharynx and are mute.

Frigatebirds

Order: Suliformes   Family: Fregatidae

Frigatebirds are large seabirds usually found over tropical oceans. They are large, black, or black-and-white birds, with long wings and deeply forked tails. The males have coloured inflatable throat pouches. They do not swim or walk and cannot take off from a flat surface. Having the largest wingspan-to-body-weight ratio of any bird, they are essentially aerial, able to stay aloft for more than a week.

Boobies and gannets
Northern gannet

Order: Suliformes   Family: Sulidae

The sulids comprise the gannets and boobies. Both groups are medium-large coastal seabirds that plunge-dive for fish.

Anhingas

Order: Suliformes   Family: Anhingidae

Anhingas are cormorant-like water birds with very long necks and long, straight beaks. They are fish eaters which often swim with only their neck above water.

Cormorants and shags

Order: Suliformes   Family: Phalacrocoracidae

Cormorants are medium-to-large aquatic birds, usually with mainly dark plumage and areas of coloured skin on the face. The bill is long, thin, and sharply hooked. Their feet are four-toed and webbed.

Pelicans
Brown pelican

Order: Pelecaniformes   Family: Pelecanidae

Pelicans are very large water birds with a distinctive pouch under their beak. Like other birds in the order Pelecaniformes, they have four webbed toes.

Herons, egrets, and bitterns
Snowy egret

Order: Pelecaniformes   Family: Ardeidae

The family Ardeidae contains the herons, egrets, and bitterns. Herons and egrets are medium to large wading birds with long necks and legs. Bitterns tend to be shorter necked and more secretive. Members of Ardeidae fly with their necks retracted, unlike other long-necked birds such as storks, ibises, and spoonbills.

Ibises and spoonbills

Order: Pelecaniformes   Family: Threskiornithidae

Members of this family have long, broad wings, are strong fliers and, rather surprisingly, given their size and weight, very capable soarers. The body tends to be elongated, the neck more so, with rather long legs. The bill is also long, decurved in the case of the ibises, straight and distinctively flattened in the spoonbills.

New World vultures
Turkey vulture

Order: Cathartiformes   Family: Cathartidae

The New World vultures are not closely related to Old World vultures, but superficially resemble them because of convergent evolution. Like the Old World vultures, they are scavengers. However, unlike Old World vultures, which find carcasses by sight, New World vultures have a good sense of smell with which they locate carcasses.

Osprey

Order: Accipitriformes   Family: Pandionidae

Pandionidae is a family of fish-eating birds of prey possessing a very large, powerful hooked beak for tearing flesh from their prey, strong legs, powerful talons, and keen eyesight. The family is monotypic.

Hawks, eagles, and kites
Northern goshawk

Order: Accipitriformes   Family: Accipitridae

Order: Coraciiformes   Family: Alcedinidae

Kingfishers are medium-sized birds with large heads, long, pointed bills, short legs, and stubby tails.

Woodpeckers
Red-naped sapsucker

Order: Piciformes   Family: Picidae

Woodpeckers are small to medium-sized birds with chisel-like beaks, short legs, stiff tails, and long tongues used for capturing insects. Some species have feet with two toes pointing forward and two backward, while several species have only three toes. Many woodpeckers have the habit of tapping noisily on tree trunks with their beaks.

Falcons and caracaras
American kestrel

Order: Falconiformes   Family: Falconidae

Falconidae is a family of diurnal birds of prey, notably the falcons and caracaras. They differ from hawks, eagles, and kites in that they kill with their beaks instead of their talons.

Tyrant flycatchers
Eastern kingbird

Order: Passeriformes   Family: Tyrannidae

Tyrant flycatchers are Passerine birds which occur throughout North and South America. They superficially resemble the Old World flycatchers, but are more robust and have stronger bills. They do not have the sophisticated vocal capabilities of the songbirds. Most, but not all, are rather plain. As the name implies, most are insectivorous.

Shrikes
Northern shrike

Order: Passeriformes   Family: Laniidae

Shrikes are passerine birds known for their habit of catching other birds and small animals and impaling the uneaten portions of their bodies on thorns. A shrike's beak is hooked, like that of a typical bird of prey.

Vireos, shrike-babblers, and erpornis

Order: Passeriformes   Family: Vireonidae

The vireos are a group of small to medium-sized passerine birds. They are typically greenish in colour and resemble wood warblers, apart from their heavier bills.

Crows, jays, and magpies
Canada jay

Order: Passeriformes   Family: Corvidae

The family Corvidae includes crows, ravens, jays, choughs, magpies, treepies, nutcrackers, and ground jays. Corvids are above average in size among the Passeriformes, and some of the larger species show high levels of intelligence.

Swallows

Order: Passeriformes   Family: Hirundinidae

The family Hirundinidae is adapted to aerial feeding. They have a slender streamlined body, long pointed wings, and a short bill with a wide gape. The feet are adapted to perching rather than walking, and the front toes are partially joined at the base.

Tits, chickadees, and titmice

Order: Passeriformes   Family: Paridae

The Paridae are mainly small stocky woodland species with short stout bills. Some have crests. They are adaptable birds, with a mixed diet including seeds and insects.

Nuthatches

Order: Passeriformes   Family: Sittidae

Nuthatches are small woodland birds. They have the unusual ability to climb down trees head first, unlike other birds, which can only go upwards. Nuthatches have large heads, short tails, and powerful bills and feet.

Treecreepers

Order: Passeriformes   Family: Certhiidae

Treecreepers are small woodland birds, brown above and white below. They have thin, down-pointed, curved bills, which they use to extricate insects from bark. They have stiff tail feathers, like woodpeckers, which they use to support themselves vertically on trees.

Wrens

Order: Passeriformes   Family: Troglodytidae

Wrens are small and inconspicuous birds, except for their loud songs. They have short wings and thin down-turned bills. Several species often hold their tails upright. All are insectivorous.

Gnatcatchers

Order: Passeriformes   Family: Polioptilidae

These dainty birds resemble Old World warblers in their structure and habits, moving restlessly through the foliage seeking insects. The gnatcatchers are mainly soft bluish grey in colour and have the typical insectivore's long, sharp bill. Many species have distinctive black head patterns (especially males) and long, regularly cocked, black-and-white tails.

Dippers

Order: Passeriformes   Family: Cinclidae

Dippers are named for their bobbing or dipping movements. They are unique among passerines for their ability to dive and swim underwater.

Kinglets

Order: Passeriformes   Family: Regulidae

The kinglets are a small family of birds which resemble the titmice. They are very small, insectivorous birds in the genus Regulus. The adults have coloured crowns, giving rise to their name.

Leaf warblers

Order: Passeriformes   Family: Phylloscopidae

Leaf warblers are a family of small insectivorous birds found mostly in Eurasia and ranging into Wallacea and Africa. The Arctic warbler breeds east into Alaska. The species are of various sizes, often green-plumaged above and yellow below, or more subdued with greyish-green to greyish-brown colours.

Old World flycatchers

Order: Passeriformes   Family: Muscicapidae

This a large family of small passerine birds restricted to the Old World. Species below only occurs in Canada as vagrants. The appearance of these birds is highly varied, but they mostly have weak songs and harsh calls.

Thrushes and allies
Western bluebird

Order: Passeriformes   Family: Turdidae

The thrushes are a group of passerine birds that occur mainly but not exclusively in the Old World. They are plump, soft plumaged, small to medium-sized insectivores or sometimes omnivores, often feeding on the ground. Many have attractive songs.

Mockingbirds and thrashers

Order: Passeriformes   Family: Mimidae

The mimids are a family of passerine birds which includes thrashers, mockingbirds, tremblers, and the New World catbirds. These birds are notable for their vocalization, especially their remarkable ability to mimic a wide variety of birds and other sounds heard outdoors. The species tend towards dull greys and browns in their appearance.

Starlings
Immature female European starling

Order: Passeriformes   Family: Sturnidae

Starlings and mynas are small to medium-sized Old World passerine birds with strong feet. Their flight is strong and direct and most are very gregarious. Their preferred habitat is fairly open country, and they eat insects and fruit. The plumage of several species is dark with a metallic sheen.

Waxwings

Order: Passeriformes   Family: Bombycillidae

The waxwings are a group of birds with soft silky plumage and unique red tips to some of the wing feathers. In the Bohemian and cedar waxwings, these tips look like sealing wax and give the group its name. These are arboreal birds of northern forests. They live on insects in the summer and berries in winter.

Silky-flycatchers

Order: Passeriformes   Family: Ptiliogonatidae

The silky flycatchers are a small family of passerine birds which occur mainly in Central America. They are related to waxwings and most species have small crests.

Accentors

Order: Passeriformes   Family: Prunellidae

Accentors are small, fairly drab species superficially similar, but unrelated to, sparrows. However, accentors have thin sharp bills, reflecting their diet of insects in summer, augmented with seeds and berries in winter.

Old World sparrows

Order: Passeriformes   Family: Passeridae

Old World sparrows are small passerine birds. In general, sparrows tend to be small plump brownish or greyish birds with short tails and short powerful beaks. Sparrows are seed eaters, but they also consume small insects.

Old World buntings

Order: Passeriformes   Family: Emberizidae

Emberizidae is a family of passerine birds containing a single genus. Until 2017, the New World sparrows (Passerellidae) were also considered part of this family.

New World sparrows
Savannah sparrow

Order: Passeriformes   Family: Passerellidae

Until 2017, these species were considered part of the family Emberizidae. Most of the species are known as sparrows, but these birds are not closely related to the Old World sparrows which are in the family Passeridae. Many of these have distinctive head patterns.

Yellow-breasted chat

Order: Passeriformes   Family: Icteriidae

This species was historically placed in the wood-warblers (Parulidae) but nonetheless most authorities were unsure if it belonged there. It was placed in its own family in 2017.

Troupials and allies
Hooded oriole

Order: Passeriformes   Family: Icteridae

The icterids are a group of small to medium-sized, often colourful passerine birds restricted to the New World and include the grackles, New World blackbirds, and New World orioles. Most species have black as a predominant plumage colour, often enlivened by yellow, orange, or red.

New World warblers
Canada warbler
