From Wikipedia, the free encyclopedia

The great horned owl is the provincial bird of Alberta

Alberta is a landlocked province within Canada, bordered by British Columbia to the west, Saskatchewan to the east, the North-West Territories to the north, and the U.S. state of Montana to the south.[1] The northern part of the province is largely boreal forest, leading into the Great Plains in the south-east. The south-west portion of the province is generally temperate coniferous forest, bordered by the Rocky Mountains.[2] These different ecosystems, along with the border formed by the Rocky Mountains, contribute to the diversity of birds in the province. Notably, several "eastern" and "western" pairs can be seen in Alberta, such as the eastern bluebird and western bluebird.[3] The Central Flyway passes through Alberta, along with a portion of the Prairie Pothole Region, contributing to the variety of bird species which breed in, or migrate through, the province.[4][5]

Unless otherwise noted, the information provided is from the Official List of the Birds of Alberta, produced by the Alberta Bird Record Committee, which contains 438 species as of April 2023.[6] Of these, 125 are accidentals, eight were introduced to Alberta, one species is extinct, and another is possibly extinct. 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).[7] 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 describe some categories of occurrence.

  • (A) Accidental - a species that rarely or accidentally occurs in Alberta
  • (B) Breeding - a species that currently breeds or has bred in Alberta
  • (E) Extinct - a recent species that no longer exists
  • (Ex) Extirpated - a species that no longer occurs in Alberta, but populations still exist elsewhere
  • (I) Introduced - a species that has been introduced to Alberta by the actions of humans, either directly or indirectly

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.[8]: 13–17 

Pheasants, grouse, and allies

[edit]

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.[8]: 24–27  Many species are gamebirds or have been domesticated as a food source for humans.[9]

Grebes

[edit]

Order: Podicipediformes   Family: Podicipedidae

Horned grebe

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.[8]: 30 

Pigeons and doves

[edit]

Order: Columbiformes   Family: Columbidae

Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere. They have strong flight muscles, allowing them to take off almost vertically and fly for long distances.[8]: 32 

Cuckoos

[edit]

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.[8]: 57–58 

Nightjars and allies

[edit]

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.[8]: 40 

Swifts

[edit]

Order: Apodiformes   Family: Apodidae

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.[8]: 48 

Hummingbirds

[edit]

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.[8]: 52 

Rails, gallinules, and coots

[edit]

Order: Gruiformes   Family: Rallidae

Rallidae is a large family of small to medium-sized birds which includes the rails, crakes, coots, and gallinules. Many species 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.[8]: 61–63 

Cranes

[edit]

Order: Gruiformes   Family: Gruidae

Whooping crane

Cranes are large, long-legged birds who fly with their distinctive long necks outstretched. Most have elaborate and noisy courting displays or "dances". The breeding grounds for the only wild population of whooping cranes is in Wood Buffalo National Park in northern Alberta.[8]: 67–69 

Stilts and avocets

[edit]

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.[8]: 110 

Plovers and lapwings

[edit]

Order: Charadriiformes   Family: Charadriidae

Killdeer

The family Charadriidae includes 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.[8]: 105 

Sandpipers and allies

[edit]

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 direct competition for food.[8]: 116–117 

Skuas and jaegers

[edit]

Order: Charadriiformes   Family: Stercorariidae

Skuas and jaegers are medium to large seabirds with strongly hooked talons, hooked beaks, and webbed feet. They are pelagic birds and feed on a variety of animals—such as fish, bird eggs, and lemmings—by hunting, scavenging, or kleptoparasitizing them.[15][16][17]

Auks, murres, and puffins

[edit]

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.[8]: 123–125 

Gulls, terns, and skimmers

[edit]

Order: Charadriiformes   Family: Laridae

Laridae is a family of seabirds consisting of gulls, terns, and skimmers. Gulls are typically grey or white, often with black markings on the head or wings. Terns are generally smaller than gulls with more pointed wings and bills, many also having forked tails which help with aerial manoeuvrability. Both species can be found inland near lakes and rivers, however gulls have adapted well to human presence and can often be found in urban centers.[8]: 127–129  Skimmers have not been recorded in Alberta.[6]

Loons

[edit]

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 are almost hopeless on land, because their legs are placed towards the rear of the body.[8]: 73–74 

Cormorants and shags

[edit]

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.[8]: 102–103 

Pelicans

[edit]

Order: Pelecaniformes   Family: Pelecanidae

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.[8]: 94–97 

Ibises and spoonbills

[edit]

Order: Pelecaniformes   Family: Threskiornithidae

The family Threskiornithidae includes the ibises and spoonbills. They have long, broad wings. Their bodies tend 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.[8]: 97–98 

New World vultures

[edit]

Order: Accipitriformes   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.[8]: 131–133 

Osprey

[edit]

Order: Accipitriformes   Family: Pandionidae

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.[8]: 164–165 

Falcons and caracaras

[edit]

Order: Falconiformes   Family: Falconidae

Vireos are a group of small to medium-sized passerine birds mostly restricted to the New World, though few other members of the family are found in Asia. They are typically greenish in colour and resemble wood warblers apart from their heavier bills.[8]: 255–256 

Shrikes

[edit]

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.[8]: 270

Treecreepers

[edit]

Order: Passeriformes   Family: Certhiidae

Treecreepers are small woodland birds, brown above and white below. They have thin pointed down-curved bills, which they use to extricate insects from bark. They have stiff tail feathers, like woodpeckers, which they use to support themselves on vertical trees.[8]: 373–374 

Gnatcatchers

[edit]

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.[8]: 377–378 

Wrens

[edit]

Order: Passeriformes   Family: Troglodytidae

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.[8]: 380–381 

Starlings

[edit]

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.[8]: 381–383 

Dippers

[edit]

Order: Passeriformes   Family: Cinclidae

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.[8]: 391–393 

Old World flycatchers

[edit]

Order: Passeriformes   Family: Muscicapidae

Old World flycatchers are a large family of small passerine birds. These are mainly small arboreal insectivores, many of which, as the name implies, take their prey on the wing.[8]: 387 

Accentors

[edit]

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.[8]: 289–291
