The white Peking ducks of which one to two million are reared every year in Taiwan as egg layers are also descended from the mallard. Thanks to long selection using modern breeding techniques, the Pekings spend their days busily laying eggs, producing some 340 per year. Can't we imagine that looking at the 10 or so eggs in its own clutch, the mallard feels a reflected glory at having such prolific descendants?
台灣每年養一、二百萬隻孵蛋用的白色菜鴨也是綠頭鴨後代，經過現代生殖技術的長期選育，菜鴨日日忙著孵蛋，一年產上三百四十個，看看自己巢裡十枚左右的蛋，綠頭鴨想來也該「與有榮焉」，竟然有如此出息的子嗣？
