Comment: This bat is thought to be common in caves of central and southern California, but few actual records are avail¬ 
able. This species is probably a permanent resident in most of its range (Barbour and Davis, 1969). It roosts in small 
colonies in rock crevices and buildings, and occasionally in caves, mines, and tree cavities.
