- Аннотация: There are three related systems of population: undeveloped land, built-up areas and wetland communities.The first of them form a community floodplain: meadow-steppe, field and floodplain meadow types. The second- the population of birds, lowland marsh, lake and river: Irtysh and Tobolsk types, the third - synanthropicornithocomplexes. Major trends of territorial changes in abundance and distribution of birds in the forest andsteppe in the first half of summer determine of afforestation plowing, humidification, wetlands, water contentand flow of water bodies, as well as built-on area, ruderal and anthropogenic habitats increased food capacity ofcities and towns. Increase in built-up and the appearance of landfills increases the density of the population ofbirds. Territorial heterogeneity of bird population research in forest and steppe in the second half of summer(from July 16 to August 31) is determined by forestation, building, water area, wetlands, human food resources,plowing, ruderal and largest city. Seasonal differences between the structure of bird related to the post-breedingdispersion of species and late birds migrations. Afforestation water cut and wetlands remain valid. Differencesin the impact of zoning and heat supply landscape is not significant. This emphasizes the dominant influenceof agricultural and residential load on forest-steppe and steppe landscapes, reducing landscape-geographicalboundaries between the steppe and forest-steppe. Thus, in I and II part of the summer the main territorial changesof birds population in steppe of Western Siberia and Northern Kazakhstan are similar and related to human foodresources, afforestation, moisture and water habitats.
