List of Birds of Iowa

List Of Birds Of Iowa

This is a list of all birds ever seen in Iowa, based on the list published by the Iowa Ornithologists' Union. The following markings are used:

• (C) = Casual: seen more than ninety times in the past ten years but more than ten times.
• (A) = Accidental: seen fewer than four times in the past ten years.
• (E) = Extinct; a recent member of the avifauna that no longer exists.
• (I) = Introduced: The species was introduced, either directly or indirectly, to North America through the actions of humans.

Birds listed as either casual or accidental should not be expected to be found anywhere in Iowa with regularity. Except for the casual and accidental birds, only birds that are considered to have established, self-sustaining, wild populations in Iowa or, in the case of extinct species, have had such populations in Iowa in the past are included on this list. This means that birds that are considered probable escapees, although they may have been sighted flying free in Iowa, are not included on this list. All birds on this list are found commonly in Iowa, 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. Introduced, casual, accidental, and extinct species are included in the total species counts for North America and Iowa.
