Abstract

A total of 18 invasive bird species has been introduced into or have expanded their range to include Iowa. These include ten non-North American species, one North American species that has been displaced and now is established in Iowa, and seven native species that have been released to reestablish Iowa populations. Twelve of those are regularly occurring species in Iowa, and they comprise 3.0% (12 of 404) of the species known from Iowa and 5% (10 of 199) of Iowa's nesting avifauna. These percentages are similar to those found in neighboring states. Several more species are likely to become established in the near future. Two invasive species, European Starling (Sturnus vulgaris) and House Sparrow (Passer domesticus), are among the most numerous species found in Iowa and have negative effects on other species. Most of the other invasive bird species seem to have little effect on other bird species. Two species, Mute Swan (Cygnus olor) and Eurasian Collared-Dove (Streptopelia decaocto), are close to becoming established in Iowa. Both have the potential to be harmful to other bird species.
