Mammals

There are more than 50 mammal species found in the Upper Mississippi River corridor. One, the Indiana bat, is a federally-listed endangered species that spends the winter hibernating in caves in Indiana, Kentucky, and Missouri. In the spring and summer, Indiana bats leave their caves, sometimes flying hundreds of miles to roost and raise their young under the loose bark of dead and dying trees. Roost sites are located near rivers and streams where the bats can forage for the abundant insects that are their main food source. Indiana bats are known to roost in the bottomland forests of Mark Twain NWR Complex.
