Penguin poop can be seen from space

No, seriously. The combination of background colouring from satellite images and the penguin's formidable gastrointestinal prowess allows the Emperor penguin (and others too) to be tracked by satellites orbiting the Earth. Background colouring comes handy when all that you're looking over is white sheets of ice over which penguin poop marks can easily be discer
ned- in fact, new penguin colonies have been discovered using this method. Peter Fretwell, who led one of the studies, and colleagues totted 595,000 penguins, which is almost double the previous estimates of 270,000-350,000 emperors. The count is thought to be the first comprehensive census of a species taken from space, and there's virtually no environmental impact occurring due to research too.

Now to the pooping part: A study (see source 1) focused on Adélie and Chinstrap penguins shows that these birds can poop at four times the pressure that humans can. They sit at the edge of nests and poop forty centimetres backwards. That's really impressive given the height of the penguins is roughly 60 centimetres.
