St. Andrew's Bay, South Georgia
King penguins return to South Georgia's beaches each spring, navigating through a beach full of elephant seals to reach their colony and their hungry chicks. Adult penguins possess a sleek, tightly packed coat of feathers that allows them to thrive in freezing subantarctic waters, but loses efficacy over many months. Now, these penguins must undergo a "catastrophic moult", a process in which they shed and replace all four layers of their plumage. For the next month, they will remain land-bound and be unable to feed, but once complete they will be ready to return to the sea, to feed.
