š¦Prorev Frank is a Western Barbastelle !
Barbastelles roost in splits or behind looseĀ barkĀ of trees all year, generally in matureĀ deciduousĀ forests, as well as rock crevices and within human buildings. In centralĀ Italy, tall deadĀ beechĀ in unmanaged woodland were found to be preferred as roost trees.Ā While barbastelles typically remain within a single roosting area, they move between individual roosts with great frequency !
Barbastelles migrate to underground roosting sites over the winter, although they may stay within arboreal roosts in the beginning of the season. Winter roosting sites include naturalĀ cavesĀ and human structures such asĀ basements,Ā minesĀ andĀ bunkers. Barbastelles are relatively resistant to cold conditions, and are typically found hibernating in cold sites and in exposed positions ! (Source)
