Ducks are waterfowl known for their distinctive waddling walk and quacking sounds. They have broad bodies, short necks, and webbed feet, which make them excellent swimmers. Ducks can be found in various habitats, including ponds, lakes, and rivers. They often feed on plants, insects, and small fish, using their bills to filter food from the water. These birds are social creatures and often live in groups called flocks. Many species of ducks migrate seasonally, traveling long distances to find warmer climates during winter. Ducks are also popular in farms and backyards, where they are raised for their eggs and meat.
