DUCKS, GEESE, AND SWANS
COMPARED TO many groups of birds, ducks, geese, and swans are easy to recognize. Nearly all have a flattened beak, short legs, and webbed feet. Most are strong fliers. Ducks, geese, and swans spend much of their life on or near water. Collectively, they are often known as waterfowl.
