Small water birds, such as coots, are aquatic birds that are typically smaller than other waterfowl. Coots are members of the rail family and are found in wetlands, ponds, and lakes throughout the world. They have dark feathers, short legs, and lobed toes which help them to swim and walk on soft mud. Coots feed on aquatic plants, insects, and small fish. They are also known for their loud calls and territorial behavior.
