A short streamed discussion followed by an audio stream of bats hunting in the skies above western Massachusetts, using a heterodyne bat detector to bring their calls into the human audible range. During the discussion, bat researcher Erin Ruggiano will present about the bat species we expect to hear, as well as other bats in this region and systems to manage and protect them. With any luck, we will hear the Little Brown Bat (Myotis lucifugus), an endangered species that was recently heard at Mass Audubon Arcadia Wildlife.
