Many others are endangered, such as the gray bat and the Indiana bat.

This Indiana bat is endangered mainly due to human disturbance within the caves.

Indiana bats live an average of 5 to 9 years, but some have reached 12 years of age.

Since about 1975, the population of Indiana bats has declined by about 50%.

There are at least 29 tree species that Indiana bats use during the summer.

During the breeding season, Indiana bats undergo a phenomenon known as swarming.

One Indiana bat was captured 20 years after being banded as an adult.

Habitat requirements for the Indiana bat are not completely understood.

Studies on the foraging needs for Indiana bats are inconclusive.

Indiana bats show an affinity for very large trees that receive lots of sunlight.
