A surprising number of popular names have attached them- 

 selves to this large, handsome swimmer that studiously avoids 

 populated regions and the sight of man; that no sportsman 

 would, or, indeed could, eat; that eludes pursuit by some very 

 remarkable diving and swimming feats, and therefore enjoys 

 popularity in names alone. Its preferences are for remote water- 

 ways at the north, where its family life is spent, only a few nests 

 being reported this side of the Canadian border; but when a hard 

 crust of ice locks up their fish, frogs, mollusks, and other aquatic 

 animal food, small companies of six or eight mergansers migrate
