In 2002, the National Audubon Society's Seabird Restoration Program, in cooperation with the Maine Department of Inland Fisheries and Wildlife and U.S. Fish and Wildlife Service Gulf of Maine Coastal Program initiated a tern restoration program on Outer Green Island in Casco Bay.  CBEP provided funding to assist with this program.  Outer Green Island is a 5.5 acre island located 5 miles east of Portland.  Historically, the island served as a tern colony until 1914.  Outer Green was selected becasue of its rich seabird nesting history and because of its remote location (hopefully reducing predator visits).

During the first season, in order to attract the target species, a resident field camp was established and 100 decoys and a solar powered CD sound system broadcasting tern colony calls were placed on the southeast corner of the island.  In just three years, the colony grew to over 650 pairs of Common Terns and 13 pairs of Roseate Terns (a federally-listed endangered species)!  In 2004, Audubon also initiated a Leach's Storm-Petrel attraction program on Outer Green Island; storm petrels nested on the island until approximately 1918, but no longer nest in Casco Bay.  The goal of this project is to re-establish a breeding site in Casco Bay.
