Seal Island National Wildlife Refuge is a 1-mile long (1.6 km) island off the coast of Maine, United States near Matinicus Island that is part of the Maine Coastal Islands National Wildlife Refuge. During any given summer season, over 100 species of birds are observed by researchers on the island. It is home to colonies of many types of seabirds, including Atlantic puffins, double-crested cormorants, razorbills, Leach's storm petrels, eiders, and black guillemots. Seal Island is the last refuge for the dwindling great cormorant population in the Gulf of Maine, with 35 pairs in 2018. A policy of eliminating predatory gulls preceded the recolonization of the island by a large mixed band of Arctic terns and common terns.
