Sea Lion Island is valued for its incredible wildlife diversity which reflects the Island’s high quality native habitats and its lack of rats and other introduced predators. Its rodent-free status assures the survival of numerous small bird species including the endemic Cobb’s wren and tussac bird. Approximately 40 breeding birds are found here, including seabirds such as the southern rockhopper, Magellanic and gentoo penguins, southern giant petrels and Falkland skua.
