Satellites discover more emperor penguins
Satellite images of guano tipped off scientists to 11 emperor-penguin (Aptenodytes forsteri) colonies that have never been seen from space before. The images raise the number of known emperor penguins by an estimated 5–10%. “It's good news because there are now more penguins than we thought,” says remote-sensing specialist Peter Fretwell. “But this story comes with a strong caveat because the newly discovered sites are not in what we call the refugia — areas with stable sea-ice, such as in the Weddell Sea and the Ross Sea. They are all in more northerly, vulnerable locations that will likely lose their sea-ice.”
