Wanna be Robin? Bat Count Help Needed News | May 29, 2025 | 0 | by Morgan McCarthy The Wisconsin Department of Natural Resources is asking state residents to participate in the “Great Wisconsin Bat Count” again this year. The effort is meant to help wildlife experts gauge the state’s bat population. Volunteers are asked to count bats on one night between June 6th and 8th and another night between July 18th and 20th. The two counts help estimate the number of bat pups that have gotten mature enough to start flying. More details on the effort are posted on the Wisconsin Bat Program website.
