Red Bat Trivia
Red bats reside in Illinois during the spring-summmer-fall and migrate south during the winter when their food supply, insects, is not available. There are twelve species of bats found in Illinois and red bats are one of the more common species. Bats have poor eyes and rely on echolocation, or supersonic sounds, to locate objects.
