Penguin Disovery
There are now 20% more known colonies of emperor penguins around Antarctica, thanks to satellite images that revealed more of the imperiled birds to scientists. Emperors are the only penguin species that breed on sea ice instead of on land, making them highly vulnerable to climate change. “Whilst this is good news, the colonies are small and so only take the overall population count up to … just over half a million penguins,” said lead researcher Peter Fretwell at the British Antarctic Survey. He made the discovery by examining images from Europe’s Sentinel-2 spacecraft. Fretwell says there still may be one or two other very small colonies yet to be discovered.
