The hibernating bats coil their large ears like rams' horns and voer their body with their wing and tail membranes to conserve body heat. This bat is a nimble late-night flyer that apparently feeds largely on moths. The pallid bat is a relatively large, light colored, big eared bat that inhabits Arizona's lower and mid elevation habitats during the summer. Winter records for pallid bats in Arziona are few. The pallid bat occurs throughout the desert southwest, northward along the western coast to British Columbia.
Pallid bats are very social with strong group cohesion.
They show affinity to specific roosting sites which include caves, tunnels, attics of houses, crevices and a variety of other locations. Apparently a great deal of thier food is taken by landing on the ground and stalking flightless prey. Consequently, this bat is sometimes caught in snap traps set for small mammals. Pallid bats are very vocal and have relatively slow flight patterns. One or two young are born into a nursery colony usually in June.
