Ducks at a Distance - A Waterfowl Identification Guide
Diving Ducks
Diving ducks frequent the larger, deeper lakes and rivers, and coastal bays and inlets. The colored wing patches of these birds lack the brilliance of the speculums of puddle ducks. Since many of them have short tails, their huge, paddle feet may be used as rudders in flight, and are often visible on flying birds. When launching into flight, most of this group patter along the water before becoming airborne.
They feed by diving, often to considerable depths. To escape danger, they can travel great distances underwater, emerging only enough to show their head before submerging again. Their diets of fish, shellfish, mollusks, and aquatic plants make them second choice, as a group, for sportsmen. Canvasbacks and redheads fattened on eel grass or wild celery are notable exceptions.
Since their wings are smaller in proportion to the size and weight of their bodies, they have a more rapid wingbeat than puddle ducks.
