Townsend’s Big-eared Bats live in the monument year-round. The females form maternity colonies in the summer to raise their young. In the winter the bats hibernate to conserve energy and rely on fat reserves built up from their summer diet of insects. While roosting or hibernating these bats use their large ears for thermoregulation, curling or uncurling their ears to conserve or release heat.
