Аннотация: Abstract—Four years of ornithological observations were conducted on the eastern slope of the Tibet–Qinghai Plateau in September–October 2011–2012 and 2017–2018. The species composition of common birdsin nine isolated forest islands were studied, and the proportions of species from various faunistic groups weredetermined. A comparison of the bird complexes from different locations revealed regional specificity in eachof them, this being related to the landscape and altitudinal characteristics, area, and ecological parameters ofthe localities. The local aviafauna can be determined as Palaearctic with a high percentage of endemic andsubendemic species. Oriental species constituted a significant proportion only on the southern macroslope ofthe Qinling Range, which apparently represents the northern periphery of a wide transitional zone betweenthe Palearctic and Oriental regions. A specific seasonal aspect of the species composition is attained due tofall bird migrations from the northern regions of the Palearctic. Among the special features of the region isthe wide penetration of forest birds into open spaces along intrazonal habitats and the intrusion of speciesfrom open areas into the borders of forest biotopes during the migration period. There is also an ecologicalgroup associated mainly with ecotones.
