Where is the largest colony of penguins?

   The island of South Georgia and the South Sandwich Islands are governed together as a territory of the United Kingdom. Located southeast of the Falkland Islands and 1,000 miles north of Antarctica, these islands are virtually unspoiled, with no roads or airports. The only access is by sea, and government permission is necessary for all visits.
   Glaciers cover more than half the area, but according to the International Penguin Conservation Work Group, mil­lions of penguins live here: 5,006,000 pairs of chinstrap penguin (Pygoscelis antarctica); 500,000 pairs of king penguin (Aptenodytes patagonicas); 2,500,000 pairs of macaroni penguin (Eudyptes chrysolophus); and 120,000 pairs of gentoo penguin (Pygoscelis papua). This remote outpost is also a breeding oasis for more than 22 million Southern fur seals (95 percent of the world's population), 250,000 albatrosses, and half the world's population of elephant seals.
