Penguin Poop Spotted from Space Reveals Hidden Colonies

Associated Press

   BERLIN - British scientists say there are more emperor penguin colonies
   in Antarctica than previously thought based on evidence of bird
   droppings spotted from space.
   A study published Wednesday by scientists at the British Antarctic
   Survey counted 61 emperor penguin colonies dotted around the
   southernmost continent, 11 more than the number previously confirmed.
   Scientists used images from Europe's Sentinel-2 satellite mission to
   look for smudges on the ice that indicated large amounts of guano, or
   penguin poop.
