In daylight Puffins, Razorbills, Guillemots and Gulls are active, whereas by night Manx Shearwater and Storm Petrels can be seen. Sea mammals such as Harbour Porpoise and Risso’s Dolphins frequent the sea around the island, with Atlantic Grey Seals occasionally reaching the shorelines in South Haven and Crab Bay.
