Abstract: The ringing data of autumn nocturnal migratory birds from 2018 to 2022 at the Nanjian Fenghuang Mountain Bird Banding Station were analyzed. The results are as follows: （1） A total of 8 459 migratory birds of 188 species belonging to 38 families and 11 orders were captured in 5 years. The dominant species were Ficedula albicilla, Ardeola bacchus and Calliope calliope.（ 2） The bird diversity index is 3.931 9, the uniformity index is 0.750 9, the dominance index is 0.038 1, the F index is 17.317 0, the G index is 4.252 5,
and the G-F index is 0.754 4. The diversity of migratory birds is relatively high at the family, genus levels. （3） The highest similarity
index of migratory birds in different years is 0.780 9 and the lowest is 0.710 5.（ 4） There are 15 species of wild birds under national key protection, 4 species of birds listed in Appendix Ⅱ of The Convention on International Trade in Endangered Species of Wild Fauna and Flora, and 14 species of birds listed in The Red List of China's Vertebrates.（ 5） In different areas of Yunnan such as Nanjian Fenghuang Mountain, migratory birds are mainly Passeriformes, which is different from the migratory birds in Pingfengjie of Hunan Province, Jiuwan Mountain and Damao Mountain in Guangxi Province, which are mainly Ciconiiformes waterfowl. （6） The diversity of migratory birds in Nanjian Fenghuang Mountain was higher than that in Dazhong Mountain of Nanhua, Longqingguan of Weishan and Jinshan Yakou of Xinping in neighboring areas. The bird diversity index, uniformity index with the dominance index are significantly negatively correlated, while the G-F index is not highly correlated with the dominance index.
