Satellites discover 1.5 million more penguins in Antarctica

Tipped off by evidence of bird poop in satellite images, researchers have now confirmed there are more than 750,000 breeding pairs of Adélie penguins (Pygoscelis adeliae) in the Danger Islands just off northeastern Antarctica, BBC reports. In western Antarctica, Adélie populations are rapidly declining because sea ice is disappearing. But so far, the Danger Islands are unaffected by warming temperatures and should be designated a marine protected area as a safe haven for these and other penguins, the researchers write in Scientific Reports.
