Duck Teaches Little Duckling A Lesson

Relationship with humans
• Domestication
Ducks have many economic uses, being farmed for their meat, eggs, feathers, (particularly their down). They are also kept and bred by aviculturists and often displayed in zoos. All domestic ducks are descended from the wild Mallard Anas platyrhynchos, except the Muscovy Duck . Many domestic 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; the wild mallard's "hull length" is about 6 inches.
FAO reports that China is the top duck market in 2004 followed by Vietnam and other South East Asian countries.
