The long-tailed Gentoo Penguin (Pygoscelis papua) at Port Lockroy on Goudier Island of the Palmer Archipelago off the northwestern coast of the Antarctic Peninsula.
The Gentoo, of the genus Pygoscelis, is most closely related to the Adélie penguin (P. adeliae) and the chinstrap penguin (P. antarcticus). It is the third largest species of penguin after the two giant species, the Emperor Penguin and the King Penguin. Gentoos reach a height of 20 to 35 inches and weigh 11 to 19 lbs.
During World War II, the British military Operation Tabarin established the Port Lockroy Station A to counteract claims by Nazi Germany and their Argentine sympathizers. which continued to operate as a British research station until January 16, 1962. In 1996, the station was renovated and is now a museum and post office operated by the United Kingdom Antarctic Heritage Trust.
