The Mallard Duck is a common waterfowl found in many parts of the world. Males are easily recognized by their vibrant green heads, while females are mottled brown. They typically inhabit freshwater lakes, rivers, and ponds, often seen dabbling for food on the water's surface. Mallards are omnivorous, feeding on a variety of plants, insects, and small fish. They are known for their distinctive quacking sound, especially the females. These ducks are also migratory, traveling long distances between breeding and wintering grounds, making them adaptable to different environments.
