1.5 million penguins found on Danger Islands

March 8, 2018

Over the last several decades, scientists have noticed a steady decline in one of Antarctica’s most treasured inhabitants — the Adélie penguin. These penguins reside exclusively along the Antarctic coast, along with the emperor penguin. However, a recent study published on March 2 in the journal Scientific Reports states that a supercolony of over 1.5 million Adélie penguins has been found in a group of islands off the tip of the Antarctic Peninsula
