The clicks are normally slow and constant, but these clicks speed up dramatically when the bats approach an object.

While the bats do form a communal roost, individuals do not huddle together to conserve energy and warmth. They occupy two roosts, using the daytime roost to rest, while only spending a few hours in the night roost before going out to forage. They have a long-night foraging period, lasting several hours. The bats use high-frequency and low-intensity echolocation calls to locate prey. The low wing loading and low aspect
