Widespread in the eastern U.S. Our most common tree bat species. Eastern Red Bat generally roosts in trees by day, but during cold weather may crawl beneath the leaf litter. Bats in the northern part of their range migrate south for the winter. (Migrants have been detected even over the ocean on pelagic trips.) Overwintering individuals are often active on mild mornings and evenings. Their solitary nature and use of trees rather than caves probably make this species less affected by White Nose Syndrome than other species.
Evening Bat and Eastern Red Bat call structures and characteristic frequencies overlap. However, characteristic frequencies of Eastern Red Bat call pulses typically vary within a call sequence, while those of evening bats are usually more consistent (B. Neece, pers. comm.). Calls also similar Tri-colored Bat and nearly identical to the locally much rarer Seminole Bat.
Insectivorous.
