Gray Bat Night-Roosting Under Bridges‪.‬

ABSTRACT--Many bat species use bridges as roosts for temporary resting places and thermal refuge between foraging bouts. We surveyed 37 bridges over waterways in northwest Georgia during the summer of 2000 and 2001 for night-roosting bats. We observed 20-30 gray bats (Myotis grisescens) night-roosting at two I-beam type bridges. Because of the long distances gray bats forage from their day roosts, these bridges may serve as important resting places. A more complete survey of bridges in northwest Georgia would be beneficial in determining the extent bridges are used as night roosts by bats. **********
