Phylogenetic analysis surports that anseranas should be placed in monotypic family anseranatidae, and the whistling ducks and the white - backed duck should be separated from subfamily anserinae and placed them into family dendrocygnidae. the family anatidae could be classified into two subfamilies, anserinae and anatinae. the results approve that the swans should be put into the tribe cygnini of subfamily anserinae as suggested by livezey ( 1996, 1997b ) and the shelducks should be placed in the tribe tadornini of subfamily anatinae, therefore, our results do not support sibley and ahlquist ' s ( 1990 ) establishment of the subfamily cygninae and placing the shelducks in the tribe anserini
