The investigation results showed that there were 26 species of the waterfowl of Anatidae, belonging to 7 orders, of which 1 species belong to gradeⅠ key state-protected species and 3 species (Cygnus columbianus, Anser albifrons and Branta ruficollis) belong to gradeⅡ key state-protected species.

结果表明：共调查记录到雁鸭类7属26种，其中国家重点保护动物4种，包括国家Ⅰ级重点保护动物1种［中华秋沙鸭］和国家Ⅱ级重点保护动物3种［小天鹅(Cygnus columbia-nus)、白额雁和红胸黑雁］。

The results demonstrated that MC1R gene of bird was relatively conserved. The results of phylogenetic analysis showed that consanguinity relations between mule duck, anas platyrhynchos and branta bernicla, anser caerulescens, anser canagica were close.The status of them were confirmed on zoologyl by means of molecular method.

可见禽类的MC1R 基因编码区序列具有高度的保守性；系统进化分析表明，半番鸭、北京鸭与雪雁、黑雁、皇雁亲缘关系相近，从分子角度验证了它们在动物学分类上的地位。

The results were the basic information to further study SNPs of MC1R gene associated with plumage color on mule duck. By using the program of Blast on GenBank, the results indicated that duck had homology with 98.4% homology with branta bernicla at nucleotide level of MC1R gene, and 92.8％～98.2% homology with other birds.

为进一步研究半番鸭羽色MC1R基因单核苷酸多态性奠定了基础；通过BLAST进行相似性搜索，结果表明，鸭与黑雁MC1R基因的核苷酸序列同源性最高为98.4％，与其他家禽的同源性也保持在92.8％～98.2%之间。
