TUESDAY

Bats Plight 7 to 8:30 p.m., Falmouth

Bats are an important part of the ecosystem in Maine, and Maine Audubon will help explain why. With Halloween around the corner, it is a great time to learn about our local bats and why we should be scared for them. Join biologist Susan Gallo as she shares her latest report and discusses the challenges facing cave-hibernating bats that could lead to their extinction by 2026. Come learn what is being done to help them and how you can lend a hand. Cost is $5.

UPCOMING

Blue Heron Stories 7 p.m., Nov. 19, in Wells

York County Audubon is hosting a lecture about Maine’s largest colonial wading bird and its close relatives. The great blue heron is often touted as one of the most widespread and adaptable birds in North America. Here in Maine they are widespread, but data has suggested a decline in their breeding population along the coast. Concerns over a population decline prompted the Maine Department of Inland Fisheries and Wildlife to conduct a comprehensive survey of breeding colonies in 2009, and to begin a statewide adopt-a-colony program called the Heron Observation Network. The evening program is free and open to the public. To learn more, go to www.york countyaudubon.org.
