Waterfowl is the category of birds that live and thrive in water. Birds like swans, geese, and ducks belong to this family, and all of them are characterized by webbed feet. These birds can be found in both seawater and freshwater environments.
Most waterfowl feed on fish, small mollusks, worms, aquatic plants, grasses, and small amphibians. Many waterfowl dive deep under the water to hunt for food. Those that plunged deep are heavier than most other waterfowl. Waterfowl tend to thrive in a wide variety of areas and climates. Luckily the waterfowl population in North America is steadily on the rise.
