Dabblers are ducks that skim food from the surface or feed in the shallows by tipping forward to submerge their heads and necks. Diving ducks, or divers, are ducks that propel themselves underwater with large feet attached to short legs situated far back on the body. Ruddy Ducks, along with American Wigeons and Canvasbacks, are divers. Green-winged Teals, Mallards, and Northern Shovelers are examples of dabblers.
