Add links
From Wikipedia, the free encyclopedia

The American robin is the state bird of Wisconsin.

This list of birds of Wisconsin includes species documented in the U.S. state of Wisconsin and accepted by the Records Committee of the Wisconsin Society for Ornithology (WSORC). As of July 2022 there were 441 species and a species pair included in the official list.[1] Of them, 92 are classed as accidental, 34 are classed as casual, 53 are classed as rare, eight have been introduced to North America, and two are known to be extinct and another is thought to be. An additional 12 species are classed as hypothetical. An additional accidental species has been added from another source.

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).[2] 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 Wisconsin as permanent residents, summer or winter visitors, or migrants. These tags are used to annotate some species:

  • (A) Accidental - species with fewer than one record every five years per the WSO
  • (C) Casual - species with at least one record every one to five years per the WSO
  • (R) Rare - species found annually but with fewer than eight records per year according to the WSO
  • (I) Introduced - species established in North America solely as result of direct or indirect human action
  • (E) Extinct - recent species which no longer exist
  • (H) Hypothetical - species which have been reported but not confirmed

Ducks, geese, and waterfowl

[edit]
Canada goose

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-five species have been recorded in Wisconsin.

New World quail

[edit]

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. One species has been recorded in Wisconsin.

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. Many species are gamebirds or have been domesticated as a food source for humans. Eight species have been recorded in Wisconsin.

Grebes

[edit]

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. Five confirmed and one hypothetical species have been recorded in Wisconsin.

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. Eight species have been recorded in Wisconsin.

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. Eight species have been recorded in Wisconsin.

Cranes

[edit]

Order: Gruiformes   Family: 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". Two species have been recorded in Wisconsin.

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 confirmed and one hypothetical species have been recorded in Wisconsin.

Skuas and jaegers

[edit]

Order: Charadriiformes   Family: Stercorariidae

Loons are aquatic birds the size of a large duck, to which they are unrelated. Their plumage is largely gray 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. Three species have been recorded in Wisconsin.

Storks

[edit]

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. Two species have been recorded in Wisconsin.

Frigatebirds

New World vultures

[edit]

Order: Cathartiformes   Family: Cathartidae

The New World vultures are not closely related to Old World vultures, but superficially resemble them because of convergent evolution.
