Uruguay Island is part of the Argentine Island group in the Wilhelm Archipelago, ~6 km from the Graham Coast of the Antarctic Peninsula. The island is ~1 km from north to south and ~500 m across. The IBA qualifies on the basis of the Imperial Shag (Phalacrocorax [atriceps] bransfieldensis) colony present and includes all of Uruguay Island.
Information on the environment of Uruguay Island is not available. The nearest scientific station is Vernadsky (UKR), located on Galindez Island ~1 km to the southwest. Vernadsky Station operates year-round and accommodates ~24 people in the summer (COMNAP, Antarctic Facilities, accessed 19/08/2010).
Approximately 134 pairs of Imperial Shag were breeding on Uruguay Island in 1986 (unpublished data S. Poncet pers. comm. 2005).
