Ragged Island (Harpswell, Maine)
Ragged Island provides habitat for a large and diverse population of nesting seabirds, including the: eider duck, black guillemot, greater black-backed gull, herring gull and osprey. In 2008 the U.S. Fish and Wildlife Service’s National Coastal Wetlands Conservation Grant program awarded a $323,000 Coastal Wetland grant to secure the protection of the 76.6-acre (310,000 m2) natural area used by seabirds for nesting on Ragged Island.
