Even in the Kuantu Nature Park, where farming has stopped on the farmland already purchased, the birds take no heed of the "political" boundaries drawn by humans, and fly into the surrounding farmers 'fields to look for food. So the city government has had to take on the role of duckherd, laying out rice grain for these wild ducks to feed on.
就連關渡自然公園裡，已收購的農地廢耕後，鳥兒對人類設定的「政治」疆界一概不予理會，飛到外圍農田吃喝起來，市政府不得不扮起養鴨人家，撒下稻穀，餵起野鴨。
