Hoping to stop the commercial slaughter of birds for women's ornamental hats, two cousins formed the Massachusetts Audubon Society in 1896. Harriet Hemenway, with the help of Minna Hall, started the organization dedicated to "Protecting the nature of Massachusetts." Mass Audubon is independent of the National Audubon Society, which was founded in 1905.
Today, Mass Audubon protects more than 35,000 acres, including a number of sanctuaries on Cape Cod, the Islands, and the South Coast.
