They even use snow-bound caves well above 7,500 feet elevation. You will see them sitting singly or in pairs on flat surfaces of walls or ceilings. These are handsome little animals, and might winter on open surfaces, or in holes and crevices, with only their faces exposed. Their faces are relatively plain. Most bats you see in Arizona caves belong to this genus.
Some species are difficult to distinguish in the field, even to experts.
Disturbance of wintering bats by cave explorers has undoubtedly contributed to the declines and local extinctions of many bat populations around the world. Some roosts should probably be closed to all entry in the colder months.
