Join a Mass Audubon guide in exploring birding hotspots at Mass Audubon’s Brewster’s Woods Wildlife Sanctuary in Concord. We’ll walk in the footsteps of William Brewster, sharing passages from his journal’s and searching for a variety of migrants on their annual passage through New England. Birders of all levels are welcome. Please wear comfortable walking shoes and bring binoculars. Sponsored by the Concord Museum, Aug. 27 @ 8-9:30 am
