Georgia DNR is looking for your help to monitor summer bat roosts across the state. This project involves counting bats exiting roosts at sunset. Think you can help? Keep reading!
NEW this season. We have removed our counting season windows. Feel free to count your bat roost as many times as you like each season! We’re trying to learn more about our bats activity periods so more counts will help.
Bats may use a variety of structures for roosting, both man-made and natural. Here are some examples:
- Bat House (find out more about installing your own bat house)
- Bat Condo
- Other Buildings
How do you count bats? First you need to figure out where bats are coming out. If it’s a bat house or bat condo, that’s easy. But other structures may have multiple areas for bats to exit. Look for signs like staining and guano (bat poop) to figure out where the bats are coming in and out.
Come early! Set up and be ready for counting at least 30 minutes before sunset. Bats usually come out before it’s completely dark.
To count bats, you should position yourself near the roost with the night sky as a background whenever possible. DO NOT shine lights at the roost to count bats. This may prevent bats from exiting. It’s also a good idea to be quiet during bat emergence.
Not all bats will leave the roost every night. You may still hear some squeaking from inside the roost, but you can stop counting when the exit slows down and bats are only coming out occasionally. You may also notice some bats coming back in. That’s a good time to stop. Most emergences will not last more than 30 minutes to an hour.

Rock Climber Bat Roost Observations
Are you a rock climber that has encountered a bat while climbing in Georgia? Report your sighting to GADNR! This data will help our biologists understand more about our Georgia bat species ranges, habitat preferences, and roosting conditions. Information provided will help to further inform future research and understanding of native Georgia bats.
