Pond Island National Wildlife Refuge is a 10-acre island in the mouth of the Kennebec River adjacent to Popham Beach. The treeless character and grass, forb, and shrub cover provides excellent habitat for nesting seabirds. In 1996, the Service, MDIFW, and the National Audubon Society initiated a tern restoration program on Pond Island. In 1999, Pond Island produced its first tern chick in over 60 years, when 10 pairs of common terns successfully nested on the island. Since 1999 Pond Island has supported Common, Arctic and the endangered roseate terns. Common eiders also nest on the island and a variety of shorebirds, songbirds, and raptors stopover during fall migration. The Service works with National Audubon Society to restore seabird populations and protect wildlife habitat on Pond Island. Each year Audubon and Refuge biologists collect information on seabird populations, food habits, productivity, and work to control predators such as great horned owls, great back-backed and herring gulls.
Pond Island is closed to public access during the seabird nesting season: April 1 to August 31.
