<br />near entrances to mines and caves used for hibernating: caves with high humidity and cool temperatures preferred
<br />with numerous crevices. This species usually roost on the more open surfaces where they are more susceptible to
<br />disturbance, Tree cavities may occasionally be used for daytime roosting, Disturbance by humans especially in
<br />hibemacula and maternity roosts can be a threat to survival of these animals (Barbour and Davis 1969).
