PLay outdoor games, snack on ice cream treats, and visit with other bird enthusiasts as we watch the evening skies for the migrating Chimney Swifts to swarm in for their evening rest as they make their way south. If you enjoy this natural history event, feel free to drop a few dollars in the jar for the Chimney Swift Tower Fund, an initiative of the Conservancy to build towers that mimic chimney's and provide shelter for the declining Swift population. Check out our prototype Tower between the bike path and the Labyrinth at the Brown Family Environmental Center.
