Pea Island National Wildlife Refuge was established in 1938 to provide nesting, resting, and wintering habitat for migratory birds, including the greater snow geese and other migratory waterfowl, shorebirds, wading birds, raptors, and neotropical migrants; to provide habitat and protection for endangered and threatened species, such as loggerhead sea turtles; and to provide opportunities for public enjoyment of wildlife and wildlands resources. The 5,000-acre refuge is located on the north end of Hatteras Island, a coastal barrier island and part of a chain of islands known as the Outer Banks, and includes beach, dunes, brackish ponds, and marshes. The bird list for Pea Island National Wildlife Refuge boasts more than 365 species.
