Site description Cockburn Island is a small, oval-shaped, ice-free island lying rising to around 450 m and 5 km northwest of Seymour Island, to the east of James Ross Island. The IBA comprises all of Cockburn Island.

Information on the environment of Cockburn Island is not available. The nearest permanent scientific station is Marambio (Argentina) located 10 km to the east, more information on which can be found under IBA Ant031.

Key Biodiversity Approximately 800 pairs of Imperial Shag (Phalacrocorax atriceps) were recorded breeding on Cockburn Island in 2006 (Lynch et al. 2008). A large colony of Adélie Penguin (Pygoscelis adeliae) and Snow Petrel (Pagodroma nivea) nests were reported on the island in 1901, although it is not known whether these species continue to breed in the area.

Non-bird biodiversity: None known.
