Not to be confused with the weapon, Wooden Bat.
When first encountered, Bats can be seen sleeping on the ceiling. However, if Gale gets too close or kills another nearby Bat, they'll wake up and fly towards Gale. Regardless of whether or not they hit Gale, the Bats will keep flying until they leave the screen. If a Bat flies off the screen, it won't count as a death and the Bat will respawn when Gale reenters the room it was in.
