List of birds of Illinois
Only birds that are considered to have established, self-sustaining, wild populations in Illinois are included on this list. This means that birds that are considered probable escapees, although they may have been sighted flying free in Illinois, are not included on this list.
This list is presented in taxonomic order and follows The Check-list of North American Birds (7th ed., 1998), published by the American Ornithologists' Union. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family accounts.
The following codes are used to denote certain categories of species:
- (A) = Accidental; recorded in no more than 2 of the last 10 years and unlikely to occur regularly.
- (E) = Extinct; a recent member of the avifauna that no longer exists.
- (I) = Introduced; population established solely as result of direct or indirect human intervention; synonymous with non-native and non-indigenous.

American sparrows, Towhees, Juncos, and Longspurs
The Emberizidae are a large family of passerine birds. They are seed-eating birds with a distinctively shaped bill. In Europe, most species are named as buntings. In North America, most of the species in this family are known as Sparrows, but these birds are not closely related to the Old World sparrows which are in the family Passeridae. Many emberizid species have distinctive head patterns. There are 28 Illinois species.
