Parker River National Wildlife Refuge was established in 1942 primarily to provide feeding, resting, and nesting habitat for migratory birds. Located along the Atlantic Flyway, the refuge is of vital stopover significance to waterfowl, shorebirds, and songbirds during pre- and postbreeding migratory periods. The refuge occupies in part, the southern three-fourths of Plum Island, an 8 mile long barrier
