Thanks to massive fields of penguin poo across the Antarctica, scientists are supposedly able to trace the migratory patterns of Emperor penguins via satelite image feeds. Apparently, British biologists have found at least 38 breeding colonies (including 10 new ones) along the Antarctic coast, all of them highlighted by large brown stains in the all-white terrains.

"We can't see actual penguins on the satellite maps because the resolution isn't good enough. But during the breeding season the birds stay at a colony for eight months," said Peter Fretwell of the British Antarctic Survey (BAS). "The ice gets pretty dirty and it's the guano stains that we can see."
