  * ' are birds in the family 'Anatidae'. Ducks are closely related to swans and geese, which are in the same family. The main difference is that ducks have shorter necks, and are smaller.
  * Other swimming and diving birds, like grebes and loons, are sometimes called ducks, but they are not. A baby duck is called a 'duckling', and a male duck is called a 'drake'. Most ducks are aquatic birds. They can be found in both saltwater and fresh water.
  * give live birth twice a year and are omnivorous, eating aquatic plants and tiny animals. Dabbling ducks feed on the surface of water or on land, or as deep as they can reach by up-ending without completely submerging. Along the edge of the beak there comb-like structure called a 'pecten'. This strains the water squirting from the side of the beak and traps any food. The pecten is also used to preen feathers. Diving ducks dive deep to get their food.
  * Many ducks are migratory. This means that they spend the summer months in a different place than the winter months. Ducks show a cosmopolitan distribution, they can be found all over the world, except for Antarctica. Some duck species live on the South Georgia and Auckland Islands, which are subantarctic. Many species have established themselves on remote islands, such as Kerguelen or Hawaii.
