Bird population of the Borisovka River Basin (Northeastern sector of the Borisovskoye Plateau, Southern Primorye)

This study characterizes the breeding avifauna of the northeastern Borisovskoye (Shufanskoye) Plateau, a previously understudied ornithological region. The research holds particular significance as most of the plateau lies within the Land of the Leopard National Park or its buffer zone. Preliminary surveys were conducted intermittently from 2003 to 2019, with intensive studies performed in June 2023 (Listvennichnaya River) and May 2024 (Abrikosovka River) within the Borisovka River tributary system. We recorded 70 bird species, predominantly breeders, including some interesting species. The paper also provides the first documented Primorye nest descriptions for Troglodytes troglodytes (Winter Wren) and Petrophila gularis (White-throated Rockthrush).
