Family: Vespertilionidae, Vespertilionid Bats view all from this family



Description Unique with big ears and small lappets that project forward from the base of each ear, extending over the snout. This small bat looks large, owing to huge ears and long, lax, yellowish-gray to blackish-brown fur. Forearm 41-49mm.

Warning Bats are susceptible to rabies, a serious viral disease that results in death if untreated. Rabid bats rarely attack humans or other animals, but bats found lying on the ground may be rabid. Never touch or pick up any bat. Stay away from any animal that seems to be acting strangely and report it to animal-control officers. If you are bitten by a possibly rabid animal, you must immediately consult a doctor for a series of injections; there is no cure once symptoms emerge.

Discussion In the open, they emit loud clicks at about 1-second intervals, sounds that are audible to humans. It is known from a variety of both arid and wooded habitats in southwestern North America.
