Both the White-Headed and the Wu-T'ou Weng are members of the same family and they have been divided into two different species. The White- Headed Weng has a white head. The plumage in front of its eyes, behind its ears and on its chin is black, while there are speckles resembling a white birth mark below its ear.
烏頭翁與白頭翁在鳥輩中同為燕雀目鵯科，過去一直被分為二個不同種。
