Tail Island (63°40′S 57°37′W) is a circular island 1.25 nautical miles (2.3 km) in diameter and 130 m high, lying midway between Egg Island and Eagle Island in the northeast part of Prince Gustav Channel. Islands in this area were first seen by a party under J. Gunnar Andersson of the Swedish Antarctic Expedition, 1901-04. Tail Island was charted by the Falkland Islands Dependencies Survey (FIDS) in 1945, and so named by them because of its relative position to Eagle and Beak islands.
