What is a difference between ducks and grebe?

Ducks and grebes are both waterfowl, but they belong to different families and have distinct characteristics. Ducks, part of the family Anatidae, typically have broader bodies and are more adapted to dabbling or diving for food on the water's surface. In contrast, grebes, belonging to the family Podicipedidae, are more specialized for diving and swimming underwater, with elongated bodies and lobed toes that aid in propulsion. Additionally, grebes often have more elaborate courtship displays and unique nesting behaviors compared to ducks.
