We have bats here but they are those little brown guys. We have an attic access in the shop. One night the wind was high and actually moved the plywood that the previous owner used to cover the access. I went out with a flashlight to get firewood (a few years before we put in electricity) and this little bat comes zooming down, drawn to the light from the flashlight and I spent a good 5 minutes just tracking the flashlight around with it following the light. I finally turned off the light and it zipped back up into the attic and I got the plywood covering back in place.
May not have bats in the belfry but we definitely have them in the attic.
