The article presents the results of automobile censuses of wintering birds of prey (Falconiformes) in the conditions of the Khanka-Razdolnaya Plain (south of Primorsky Krai) in the winter of 2023/2024. It reports the results of the analysis of changes in the number and species ratio of wintering birds of prey in comparison with previous similar studies. It also discusses possible causes of these changes. In total, 577 individuals of birds of prey belonging to ten species were encountered during the winter months of 2023/2024, with an average occurrence of 24.4 individuals per 100 km of the route. Mouse-eating birds of prey account for the main part (up to 90%) of the community of wintering predatory birds in the south of Primorsky Krai. The most numerous species, as in previous years, was the Rough-legged Buzzard Buteo lagopus, with a 50.4% share of all wintering birds of prey.
