This treeless island marks the outermost boundary of Penobscot Bay. The site has had the longest conservation presence of any island in the state with National Audubon providing stewardship since the 1960s.
This site is truly special for many Alcids, with Atlantic Puffins, Razorbills and Black Guillemots all nesting here in large numbers. In recent years, Common Murres and even a Manx Shearwater, have been prospecting here. This site is especially important for Arctic Tern, Laughing Gull, and Leach?s Storm-petrel. In total, eight species of seabirds nest here.
Despite seabird conservation interns living on the island and posted closure during the nesting season (see below), the public still attempts to land on the island every year. Such landings can have disastrous consequences on tern productivity. The threat of an oil spill here is ever present.
The island is owned by the U. S. Fish and Wildlife Service, Maine Coastal Islands National Wildlife Refuge. The island is closed to the public during the Seabird nesting season (April 1 to August 31).
