Beaked ducks are similar in size to mallard ducks. The mouth is black and the tail is yellow, so it is called spotted duck, which is coral red and easy to distinguish from other wild ducks. The body feathers are mostly grayish brown with obvious white eyebrows. The rearview mirror has metallic blue-green luster and purple luster. The male and female hair colors are similar, and the male has hooked hair at the end, so he is not good at singing. The female will make a quack, slightly smaller than the male. Spotted-billed duck has delicious taste, high nutritional value and short laying cycle. Laying eggs from March to June every year, the wholesale price of each duckling 10~ 12.5 yuan and each commercial duck is 50~ 125.
