Ivory Gull

A gleaming white bird of the frozen north, spending most of its life along shifting edges of pack ice in the Arctic Ocean. Its pristine appearance is belied by its feeding habits: the Ivory Gull often is a scavenger, eating carrion and even the droppings of other animals, and aggressively fighting over food. Seems to swim less often than most gulls. Only a very rare stray south of the Canadian border.
