Abstract: Due to the population decline of over half raptor species caused by human activities, the decline of raptors has become a
symbol of the global biodiversity crisis, and there is an urgent need to strengthen protection. From September to November 2023, a
fixed-point survey method was used for the first time in the Zhemoshan Area of Dali, Yunnan to investigate and count the species
diversity of raptors during daytime migration and transit, and to study the migration patterns of raptors. During the investigation, a total of 26 species of diurnal raptors belonging to 2 orders and 3 families were recorded, with a total of 3 674 individuals, including 1 413
individuals of uncertain species. In terms of species composition, Pernis ptilorhynchus, Buteo japonicus, Accipiter virgatus, Falco
tinnunculus, and Accipiter nisus are the top five species with the highest number of recorded individuals, accounting for 82.8% of the
total identifiable species. The number of individuals crossing the border in a single day reached its maximum on October 13th,
amounting to 519. Due to some human interference in the current Zhemoshan migration route during autumn, it is urgent for the
government to take management measures to protect it.

Key words: raptor migration, Zhemoshan, Pernis ptilorhynchus, Buteo japonicus
