A possible defensive function for calls given by bats (Myotis lucifugus) arousing from torpor

Abstract

Presentation of stimuli in a Y maze showed that Peromyscus maniculatus which inhabit hibernacula used by bats may use auditory stimuli to locate bats which have fallen from their hibernation perches. However, the intense calls (95 dB sound pressure level, linear at 10 cm) given by bats (mainly Myotis lucifugus) as they arouse from torpor may serve a defensive function by repelling the mice.
