Abstrakt: The results of bird counts averaged over the first half of summer (May 16 to July 15) from 1880 to 2019 have been analyzed to identify the spatial-typological structure and organization of the ornithocomplexes of Northern Eurasia (with interruptions, and mainly since 1960). A total of 354 researchers participated in the collection of material (over 110 years). Data processing is carried out using multivariate statistics methods, including cluster analysis and linear qualitative approximation of communication matrices. The main territorial trends in bird assemblages and environmental factors correlating with them are identified, and the relationship between the spatial variability of ornithocomplexes and the heterogeneity of habitats is assessed. The fractality of the spatial differentiation of the bird assemblageis shown. [ABSTRACT FROM AUTHOR]
