Adults, families and children 7 and up will hike the trails at twilight to listen for bat clicks and chirps with our electronic echo-locator and help identify and record species flying over the nature center pond. Participants will learn about what bats eat and where they live. They will also have the chance to examine a bat house and receive free bat house plans! Cost is $4 per person, please call 651-249-2170 to  prepay by July 23.
