Martha’s Vineyard is home to several bat species, and on Tuesday, Oct. 4, from 5:30 to 6:30 pm, the Edgartown library will host an evening all about the flying critters. While bats are often portrayed as scary or dangerous, they’re vital to the Island ecosystem. A documentary will be shown illustrating the studies BiodiversityWorks has done on the local bat population, and wildlife biologist Liz Olson will provide an update.
