Scientists Tracking Penguin Guano From Space

Emperor PenguinsBritish scientists are using satellites to find and track emperor penguin colonies from space.  When examining satellite photos of the Antarctic, scientists noticed a number of large reddish-brown areas on the ice.  After determining the spots were emperor penguin guano, the researchers had a nice method of locating colonies and used it to locate 10 new colonies.  Satellites cannot be used to see the penguins themselves, due to a lack of contrast.  But, given that penguins form colonies for 8 months of the year on the surface of the Antarctic, there is a lot of guano for satellites to find.  For more information, see CNN.
