Duck

Ducks are small to medium-sized water birds belonging to the family Anatidae (which also includes swans and geese). They typically have flat bills, short necks, and compact bodies covered in oily feathers for waterproofing. Ducks are found worldwide, inhabiting various aquatic environments such as lakes, rivers, ponds, and coastlines. They are omnivores, with diets including aquatic plants, seeds, insects, crustaceans, and small fish. Ducks are adept swimmers and can also walk on land. Many duck species are recognized by their characteristic quacking sounds.
