Duck - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-29) |
 | | Ducks are mostly aquatic birds, mostly smaller than their relatives the swans and geese, and may be found in both fresh water and sea water. |
 | | Most domestic ducks were bred from the wild Mallard, Anas platyrhynchos, but many breeds have become much larger than their wild ancestor, with a "hull length" (from base of neck to base of tail) of 30 cm (12 inches) or more and routinely able to swallow an adult British Common Frog, Rana temporaria, whole. |
 | | Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules, and coots. |
