  • At 33 acres, Calf Island is the largest offshore island in Greenwich. It is located south of Byram Harbor, approximately 3,000 feet from the mainland, and is connected at low tide to Shell Island. The Island boasts a diverse coastal habitat including tidal wetlands, intertidal flats, rocky intertidal shore, sandy beach, mixed forest, and coastal shrubland. The island provides excellent wading bird foraging habitat and is located less than a mile from Great Captain’s Island, which contains one of the largest heron and egret rookeries in Long Island Sound. Calf Island also has several significant geological features that offer a glimpse into the region’s ancient past.
