Are the bats found in Western Illinois, principally those located along the Mississippi (Clinton / Quads Cities area) on the endangered list, and if so is it an offense to kill them.

What species of bats habitat here?


Since I studied bats for two years at Western Illinois University as a graduate student, I may be able to address your question.

Yes, there are many bats in Western Illinois. Yes, they are protected by State and Federal laws. The MAIN species of bats are: the red bat and silvered-haired bat which live in forest regions and can be found under the leaves of trees during the day. The Big and Little Brown bats are the common bats found flying around houses and lamps at night and these stay in crevices or caves or similar habitats at night, even houses with outside attic entrances. I have found them on the side of trees and on the side of any structure on occasion. There are a number of other bats that can be found in Western Illinois, but they are not really common. I have found Gray bats, Eastern Pipistrels and Hoary Bats. These may be locally common.

I'm not familiar with the endanger list for bats but you can contact the Illinois History Survey in Urbana for more information.
