Materials of year-round censuses of birds carried out in four ash dumps and adjacent territories are analyzed. Using classifications of ordered objects in different habitats, four to six seasonal aspects of bird population have been distinguished. The change of composition of dominant species, indicators of density and species richness of bird community in ash dumps and adjacent territories demonstrates a considerable significance of technogenous influence on ornithocomplexes in various seasonal periods. The observed differences are determined by the change in the character of use of these bird habitats and depend on the disturbance of natural regimes and their replacement by man made ones.
