WILD GEESE, DUCKS, AND SWANS © National Geographic Society LORDLY BEARING STAMPS THE CANVASBACK A KING AMONG WATERFOWL Hardy and strong, splendid flyers and divers, "cans" often stay in the north until the lakes are covered with ice (right pair and " single" flying). From breeding grounds in the far north and west many head for Chesapeake Bay regions, where they feed on "wild celery." Often flights of thousands parade across the sky. Close relatives are the redheads (pair in left foreground and group flying) and the ring-necked ducks (beyond), most widely and aptly called "ring-bills."
