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. Bufflehead dive underwater to catch aquatic invertebrates. Diving duck, any duck that obtains its food by diving to the bottom in deep water rather than by dabbling in shallows (see dabbling duck).

They… Because they have to move efficiently underwater, divers also have compact wings that lay tightly against their body. In many places of former importance to these birds (e.g., medium-size lakes in Minnesota and Wisconsin, the Illinois River, Chesapeake Bay, coastal North Carolina) their preferred submersed aquatic plants have been lost to increased turbidity (caused by soil erosion, rough fish, industrial pollution, etc. Dabbling ducks belong to the Anatinae subfamily. It's no accident that canvasbacks, the heaviest of the pochards, are the fastest flyers among the ducks. Hence, these ducks can balance themselves properly when they are upside-down in the water.
