Parker River National Wildlife Refuge was established in 1942 to provide feeding, resting, and nesting habitat for migratory birds. The refuge occupies 4,662 acres on the southern two-thirds of Plum Island, a barrier island on the Northeast coast of Massachusetts, and is administered by the US Fish and Wildlife Service, a federal agency. Parker River is one of over 540 Refuges in the National Wildlife Refuge System, a national network of lands dedicated to "wildlife first."
National Wildlife Refuge
Thacher Island National Wildlife Refuge is home to herring and great black-backed gulls. The refuge serves as a stopover site for songbirds and other migrants to rest and feed during seasonal migration. Off-shore habitats are used by seals, waterfowl, loons, grebes, cormorants and alcids.
There are two lighthouses are only hundreds of feet apart on Thatcher Island, which makes it unique to New England. The only other twin light house is Twin Lights of the Navesink in New Jersey.
