(Newser) – Emperor penguin droppings are so concentrated that the reddish-brown guano has been spotted from space, reports the Times of London. That's a good thing because it's helping scientists pinpoint colonies of the giant birds in Antarctica and help experts track climate change affects. “The ice gets pretty dirty and it's the guano stains that we can see,” said the lead researcher, who examined satellite images of the droppings. Colonies have already began to shift due to melting.
