Waterfowl are a type of bird that live in or near water. They include the GOOSE, DUCK, SWAN, LOON, GEESE, COOT, SMEW, EIDER, and MERGANSER. The GOOSE is a large bird with a long neck and webbed feet. Ducks are smaller than GEESE and have a wide variety of colors and patterns. Swans are large white birds with long necks and black beaks. Loons are aquatic birds with pointed bills and webbed feet. GEESE are similar to ducks but larger and more aggressive. Coots are small, dark-colored waterbirds with lobed toes. Smews are small diving ducks with white and black feathers. Eiders are sea ducks with thick, insulating feathers. Mergansers are fish-eating ducks with long, thin bills.
