The nature-based conservation organization Mass Audubon hosts activities ranging from bird-watching and lectures to overnight trips and day hikes. The family-friendly Nature in the City Festival (Magazine Beach, Cambridge, April 12) offers music, food, and a scavenger hunt. Participants can join a group looking for migratory birds along the Charles River, learn about the habits of urban wildlife, and find ways to help mitigate the effects of climate change locally. Upcycled fashion items offered by Ninawa Zero Waste, with food by Samosa Man. Starting at 3 p.m., the local multi-ethnic jazz fusion band Saklamara performs.
Other spring Mass Audubon programs include: Wednesday Morning Birding (through May) and a workshop on Bumble Bees of Massachusetts (June 7), at the Boston Nature Center and Wildlife Sanctuary in Mattapan; and Bioblitz—a fun race to find and identify as many species of plants and animals as possible within a defined space and time (May 18), at Brewster’s Woods Wildlife Sanctuary, in Concord.
