title: [The spatial organization of winter bird communities in the East European and West Siberian plains].
abstract: The main trends in the territorial changes in winter bird communities and the environmental factors determining them were analyzed based on long-term counts in the East European and West Siberian plains. These trends are reduced to a decline in the winter avian complexes (in the number of species and individuals) in the north- and eastward directions and with a decrease in the degree of sheltering and feed reserves in the habitats associated with reduction in afforestation. The specific regional features of winter East European avian complexes are the larger number of species and individuals in the nemoral forest, forest-steppe, and steppe landscapes, and inland water bodies as compared with the West Siberian avian complexes, as well as an increased influence of the degree of development and agricultural transformation of landscapes.
