Site description The Duroch Islands lie several hundred metres offshore from Cape Legoupil, northwestern Trinity Peninsula, northern Antarctic Peninsula. The island group includes Wisconsin Islands in the northeast and extends to Estay Rock in the southwest, and excludes Demas Rocks (Hattersley-Smith, 1991).
The nearest permanent scientific facility is Bernardo O’Higgins Station (Chile), which has capacity for ~44 people and operates year-round ~200 m to the south at Cape Legoupil (COMNAP, Antarctic Facilities, accessed 20/08/2010).
Key Biodiversity Around 14,000 pairs of several penguin species breed in a number of groups on the Duroch Islands, with approximately 3500 pairs Gentoo (P. papua), 800 pairs Adélie (P. adeliae), and 9400 pairs Chinstrap (P. antarctica) penguins recorded in 1990 (Poncet & Poncet, pers. comm.).
Non-bird biodiversity: None known.
