Located along the northeast coast of Massachusetts, Parker River National Wildlife Refuge provides feeding, resting and nesting habitat for a wide variety of migratory birds. The refuge includes more than 4,700 acres of diverse habitats – from sandy beaches and dunes to cranberry bogs, maritime forests and freshwater marshes. The most abundant habitat on the refuge is salt marsh, one of the most productive ecosystems in nature. It’s a great place to see your favorite birds as the fall migrations begin.
