It doesn't feed when it wakes up, but it may fly around outside the cave on warm nights. These bats don’t migrate to caves and mines for winter and therefore have not been exposed to the deadly fungus. 1.

Communal night roosting behavior of Myotis lucifugus was studied in southeastern Ontario using low light level television equipment. More than 15 species of bats live in Washington, from the common little brown bat (Myotis lucifugus) to the rare Townsend’s big-eared bat (Corynorhinus townsendii). They can migrate hundreds of miles to get from summer habitats to their hibernacula, which is a roost occupied in the winter months. During July the population of bats arriving at the hibernacula consisted of adult males and nulliparous females, while in August and September subadults and post-partum females predominated.
