3 Wings vary in many ways and affect the behavior of the birds Wings vary in many ways and affect the behavior of the birds. These include: Color, size in relation to body size, shape and wing beat.Canvasback (diver) Pintail (puddle duck)

5 Diving Ducks have speculum/coverts that are white, gray or black. Canvasback Scaup Common merganser Common goldeneyeBufflehead Ringneck
6 Puddle Ducks have speculum/coverts that have color: Green, blue, purple, metallic, some white, purple, tan and brown.Blue-wing teal Green-wing teal Shoveler Wood duckMallard Gadwal Wigeon Cinnamon Teal
7 Leg placement can affect how the waterfowl feed Leg placement can affect how the waterfowl feed. All waterfowl can dive but only the divers do it consistently to get food.The bufflehead picture is of two birds. See the swirl? One just dove under.The Shovelers are dabbling.The geese, swans and mallards are feeding on land.
8 Leg Placement affects how the duck can walk on land and swim. Divers: Legs are further back making it harder to walk on land but better for swimming.LoonPuddle ducks: Legs are central, can walk on land easily.Penguin (not a waterfowl)
9 Diving ducks sit lower in the water than the Puddle duck. Puddle Diver Loon, Grebe
10 Divers run on the water to take off where as puddle ducks can take off straight up. This is because of their wing/body size. So divers are found in more open water and puddle ducks can be found in weedy marshes and on land.
