Owen Island is a small, roughly circular ice-free island situated between Pottinger Point and Round Point ~500 m from the northern coast of King George Island. The IBA qualifies on the basis of the concentration of seabirds present (in particular Chinstrap Penguin (Pygoscelis antarctica)) and includes all of Owen Island.
The nearest permanent scientific station is Comandante Ferraz (Brazil) which operates year-round on the northern shoreline of Admiralty Bay, located ~17 km to south, and which accommodates a maximum of ~40 people in the summer (COMNAP, Antarctic Facilities, accessed 24/08/2010).
Approximately 21 551 breeding pairs of Chinstrap Penguin were present at Owen Island in 1980 (Jablonski 1984). Shuford & Spear (1988b) estimated more than 12 500 breeding pairs in January 1987. Information on other bird species in the area is not available.
Non-bird biodiversity: None known.
