The colony inhabits France's subantarctic Île aux Cochons or Pig Island. Observations from the 1980s showed that it was once home to 2 million king penguins, making it the planet's largest colony of the species, and also the second largest colony of all penguins.
Following a £10 million ($13.5 million) eradication scheme and nearly a decade of work, South Georgia was officially declared rodent-free on Tuesday, the first time since humans arrived on the island more than 200 years ago.
The British territory is one of the world's last great wildlife areas. There you'll find 98 percent of the world's Antarctic fur seals, half the world's elephant seals and four species of penguins—including King Penguins with around 450,000 breeding pairs. The birdlife includes albatrosses, prions, skua, terns, sheathbills and petrels.

The arduous journey that king penguins must make in order to hunt fish to bring back to their young could become even longer as the climate warms, research suggests.
Greenpeace's ship Arctic Sunrise is on its way to Antarctica, where the crew on board will be the first humans ever to visit the seafloor in the Weddell Sea.
The three-month expedition will aim to further the case for a massive ocean sanctuary.
The first thing you notice about Marty is how much effort is takes her to swim. With a paralyzed left flipper, each breath seems a heroic effort—yet she perseveres. Marty is one of 15 (mostly) little blue penguins residing at the International Antarctic Centre in Christchurch, New Zealand. As her feeders kindly but firmly point out, this part of the International Antarctic Centre is not a zoo, but rather a "second chance facility" for penguins.
The animals—also known as "hoiho" in Māori—are known as the world's rarest penguins and are only found in New Zealand.

Rosa Rojas has some unusual neighbors. Sometimes, when she looks past her front yard to the sea, she spots a blue whale passing by.
Rojas owns a cluster of guest cabins in Punta de Choros, a quiet, 450-person settlement seven hours north of Santiago. If not for the sea, Punta de Choros wouldn't exist. The scrubby, moon-gray desert surrounding the town doesn't offer much to sustain human life. But the ocean here is as generous as the land is dry. Shellfish beds churn out valuable clams and abalone. Whales and penguins lure in tourists.
Thousands of Adélie penguin chicks in Terre Adélie, Antarctica died of starvation at the start of 2017 due to unusually thick sea ice that forced their parents to travel an extra 100 kilometers (62 miles) to find food, according to French scientists.
The colony of over 18,000 pairs of Adélie penguins suffered a "catastrophic breeding failure" that left with only two chicks surviving at the beginning of the year.
