Endangered Species

  • Roseate Tern (Federal and State-listed as Endangered)

    Roseate tern - USFWS.

    The Maine population of roseate terns experienced a significant decrease between 2003 and 2004, primarily due to mammalian predation on several of the larger tern colonies. The population has begun to recover, and in 2009 Maine supported 184 pairs of roseate terns. Unfortunately the terns only nest on five islands.

    Although the population has started to recover from recent predation issues, 96 percent of the roseates currently nest on two non-refuge islands, Eastern Egg Rock and Stratton Island.

  • Arctic Tern (Maine Threatened)

    Arctic Tern

    In 2009, the State of Maine supported 4,070 pairs of Arctic terns, nesting on 10 islands. Arctic terns travel an amazing distance during their annual migration. Each year the birds leave their nesting islands in Maine, fly across the Atlantic Ocean, travel south to Africa, and spend much of the winter feeding along the Antarctic coastline before heading north to start the breeding season in May and June. We estimate this to be an annual migration of over 28,000 miles.

    The oldest known Arctic tern is a 34 year-old Petit Manan Island bird!!

  • Atlantic Puffin (Maine Threatened)

    Atlantic puffin - USFWS.

    Maine represents the southern boundary of Atlantic puffin breeding in the United States. In 2009, approximately 985 pairs of Atlantic puffin bred on four islands in Maine.

    Maine Coastal Islands National Wildlife Refuge supports 90 percent of the Atlantic puffins breeding in the United States.

  • Razorbill (Maine Threatened)

    Razorbills - USFWS.

    Maine represents the southern boundary of razorbill breeding in the United States. In 2009, approximately 600 pairs of razorbills bred in Maine. Razorbills are currently breeding on six islands in Maine, four of which are part of Maine Coastal Islands National Wildlife Refuge.

    In 2006, the refuge and our conservation partners completed the first Gulf of Maine razorbill census. We documented over 2,100 razorbills.
