When the Taiwanese fanya duck (descended from the Brazilian Muscovy duck, Cairina moschata), which was domesticated only recently, sees migratory birds passing by on their way south or north, its urge to fly is stimulated, and it may briefly take to the air; however, its strength soon fails, and it cannot fly far.
雖然馴化不久的台灣番鴨見到候鳥南飛、北返，被激起的飛行慾望可能敦促著它騰空而去，但總是力有未逮，飛竄不遠。
