About Straitsmouth Island
Encompassing most of a rocky island 500 feet from the mainland in Rockport, the wildlife sanctuary is adjacent to the town-owned historic lighthouse and lies within a designated Important Bird Area (IBA).
The island is covered with a dense vegetation of shrubs, brambles, and poison ivy, which make access to and across the island difficult. Mass Audubon is working with the Town of Rockport and the Thacher Island Association to restore and maintain the lighthouse and lighthouse keeper residence, which are both historically significant structures.
