Parker River National Wildlife Refuge is a wildlife sanctuary encompassing the majority of Plum Island in northeastern Essex County, Massachusetts, 5 miles southeast of Newburyport. It was established in 1942 primarily to provide feeding, resting, and nesting habitats for migratory birds. Located along the Atlantic Flyway, the refuge is of vital stopover significance to waterfowl, shorebirds, and songbirds during migratory periods.
