Life is tough for penguins in Antarctica. The tuxedoed waddlers are suffering from general pollution, climate change-driven habitat loss, resource competition from invasive species, dwindling food resources due to expanding fisheries, and weakened immune systems, possibly from all this stress (little wonder). But not all penguin populations are hurting. Gentoo communities are actually growing, and they may have their bathroom habits to thank. Time-lapse images of a Gentoo colony on Cuverville Island reveal that when the birds move into densely snow covered areas, their guano spurs melting of snow and ice. It’s likely the albedo effect at work: the guano’s dark, heat-absorbing color may trap more Antarctic sunlight than the surrounding white landscape, which reflects light.
