Literature:

Kurta, A. 1995. Mammals of the Great Lakes Region. University of Michigan Press, Ann Arbor. 376 pp.

This species hibernates in caves or abandoned mines where the temperature is usually between 36 and 45°F.

After hibernation, a northern bat migrates to summer quarters located anywhere in the Great Lakes region; however, this bat is most abundant in summer in areas near hibernacula. Males roost alone while females gather in maternity colonies containing up to 60 adults. Some northern bats seek shelter in barns, behind house shutters, or under wooden shingles, but most shun man-made retreats. Using radiotracking techniques, one of my graduate students recently located 18 trees occupied by this species. His data indicate that northern bats have preference for cavities within silver maples, although they also roost in hollow green ash and occasionally underneath the loose bark of dead trees.

This species most often feeds within forests, below the canopy but above the shrub layer. It preys upon moths, beetles, bugs, caddisflies, stoneflies, and other insects.
