These ducks are using a section of the iced over harbor on the Main River in Hassfurt as a “rest stop” of sorts. A little known fact about the duck is that it is a clean bird. Given the opportunity, a duck would prefer not to use the water it swims and eats in as a bathroom. Here, ducks are using a section of the ice for just that purpose. Look closely at the photograph and you will notice several “spots” used as open-air urinals.
