Possession Islands

The Possession Islands (71°56′S 171°10′E) are a group of small islands and rocks extending over an area of about 7 nautical miles (13 km; 8.1 mi), lying in the western part of the Ross Sea, lying 5 nautical miles (9.3 km; 5.8 mi) south-east of Cape McCormick, in Victoria Land, Antarctica. The Possession Islands were named by Captain James Clark Ross, Royal Navy, in commemoration of the planting of the British flag here on January 12, 1841. Important Bird Area A 276 ha (680 acres) site comprising the whole of Possession Island has been designated an Important Bird Area (IBA) by BirdLife International because it supports about 111,000 breeding pairs of Adélie penguins, based on ground counts made from 1981 to 2012. A significant south polar skua colony is also present on the island. Features Named features, from south to north, are: Heftye Island 71°59′S 171°06′E.
