Most likely you've observed bats flying in warm weather over a body of water, a field, or even a road. Have you ever been curious about where those bats spend the day? Female bats of some species form maternity colonies in manmade or natural structures to raise their pups, and use bat boxes, old houses or barns, tree cavities, or even old mines. Now you can help bat biologists with SC Department of Natural Resources find and count bats emerging from their daytime roost!

What is it?

SC Bat Watch is a citizen science project in South Carolina that monitors bat roost sites.

This project involves counting bats emerging from a maternity roost twice (or more, if you want to!) during the summer.

The lack of basic information about many bat species is often due to how challenging they are to study. Sadly, we do know many bat species in North America have been drastically declining due to White Nose Syndrome (WNS), a devastating fungal disease.

Of the 14 species of bats found in SC, eleven are considered species of greatest conservation need. A few of these species have been known to utilize bat boxes and man-made structures for their maternity colonies (ex: Little Brown Bats).

By helping monitor roosting bats, you will be collecting valuable information on both common and at risk-species.

Who and When?

Anyone can participate! If you know of a maternity colony of bats you can count at least twice during the summer, you can participate. Since most bat colonies are on private land, we rely on land owners and volunteers to report colonies and conduct emergence counts. Emergence counts should be conducted when the temperature is above 60°F.

SC Bat Watch project offers 2 levels of involvement: If you choose to be a Bat Tracker, conduct 1 count within each timeframe below. Bat Enthusiasts count at least 2 times within each timeframe.

The first range of dates = pre-volancy; pups are not yet flying. The second range = post-volancy; pups are flying and will be included in the emergence count.

Level May 15 – June 15 July 1 – July 31
Bat Tracker! 1 count 1 count
Bat Enthusiast!! 2 counts 2 counts


Read the Bat Watch instructions, data sheets, and bat ID guide. You have the option of entering your count data in the field or at home using: 1) Survey123 App, 2) web browser, 3) email or 4) mail. See Data Submission section at the bottom for more info.

Important: Bats are a vital part of our natural ecosystem, servicing as a natural pest controller and pollinator. Look and learn about these wonderful animals from a distance -- Never touch a bat! In the United States, cases of human rabies is extremely rare, with only 1 to 3 cases reported annually (CDC, 2017). In the last 10 years, South Carolina contributed less than 2% of all national rabid cases in animals. Within this same time frame, bats were reported to be the 4th most likely source of rabies within our state (8% total cases) after racoons, skunks and foxes. If you find a fresh (not decomposed) dead bat, please contact Jennifer Kindel (864-419-0739, immediately. If you are concerned about potential rabies exposure, please contact the SC Department of Health and Environmental Control.

Do you know of an existing bat colony?

Great! To use that colony to participate in Bat Watch, print out the data sheets and get ready for your count. If you can't commit to more than one count per year, simply report your bat box/roost online at SCDNR.

No - Consider putting up a bat box to provide a home for bats in your neighborhood. Bat Conservation International (BCI) offers plans for building your own bat box, links to businesses that offer bat boxes that have met the standards of BCI's Bat Approved Certification Program, as well as helpful tips for where to place your bat box. Also, consider checking with your local state park – they may already have a bat box and might be willing to let you conduct an emergence count.

Ready to practice?

Jon Gillespie has kindly provided a video of Brazilian free-tailed bats emerging from boxes at Sunrift Adventures below. How many bats can you count? In the field, each person would be assigned one box, so count one box at a time. Beware, the middle one is a challenge! The total tally is located at the very bottom of this page to check your numbers. Pro tip: bring a tally counter or use a free tally counter app to help you keep track.
