Duck diving. Unidentified duck (family Anatidae) diving underwater to catch a worm. A diving duck forms a pocket with its breast and flank feathers that surrounds the wing,preventing it from getting wet. Dry wing feathers are essential for staying afloat at the surface. Paddling with its feet held towards the back of its body allows the duck to move downwards in the water | |
