The big brown bat is one of several hibernating bat species. Greater horseshoe male bats often hibernate in clusters, but females and all lesser horseshoes tend to be more solitary. During hibernation they often wake up and move in their search for suitable temperatures. So, hibernating bats should be left alone. Greater and Lesser Horseshoe bats, along with a few other types use the caves to hibernate in the winter. This uses up their stored food and they may even die.

They do awake periodically to relocate, find water, or urinate. The combined weight of the animals often causes the branches to break. During hibernation, bats lower their body temperature and metabolism for an extended period of time, using the body fat theyve accumulated to sustain them until spring. In spring, bats emerge from hibernation and migrate to. When a bat hibernates, its body temperature drops until it comes close to the temperature outside. Bats look for a cave or other hibernating site with an optimum temperature varying from 41 to 58 degrees. This is caused by their roosting behaviour of forming dense clusters of up to 30 bats hanging from one small branch.
