This handsome migrator has a taste for wild celery and a distinctive sloping profile the envy of other, less slopeful ducks. He summers and sluts around as far north as Alaska, where he really can see Russia on a clear day. In the winter, he rehabs from his bacchanalian interlude in the Betty Ford of bird habitats: U.S. coastal blue states and in the Mexican sun. Hang in there, Canvasback, we love your style.
