The Massachusetts Audubon Society's Boston Nature Center in Mattapan offers a home to more than 150 species of birds. And a winter afternoon offers up evidence of a few of them: Three-toed footprints of wild turkeys dot snowy paths like small dinosaur tracks; and in the leafless trees, robins and white-throated sparrows chirp as they flit from branch to branch.

The Mattapan sanctuary has been around since the late 1990s, but Mass Audubon itself is more than 100 years old and now owns nearly 40,000 acres of land throughout the state.
