Mexico and Costa Rica. Its breeding grounds extend from North Dakota 

 to the Arctic ocean. 



Like the Mallard and Baldpate it comes into the shallow waters at 

 dusk to feed on aquatic weeds, insects and crustaceans. Its note is seldom 

 heard by day but while coming into the feeding grounds at night with the 

 widgeons, l)lack ducks and mallards, the hoarse muffled quack of the duck 

 and the mellow whistle of the drake are heard mingled with w^histling of the 

 Widgeon and the loud calls of the Black duck. In the springtime the 

 drakes often give vitterance to low soft notes which seem to flow from deep 

 down in the throat, especially while perfonning curious courting antics in 

 the presence of the ducks.
