The population of birds of the Privasyuganye (in borders of the Tomsk region)

The population of birds of natural and anthropogenous landscapes of Privasyuganya in borders of Kargasoksky district of the Tomsk region is investigated. Quantitative and quality indicators of specific wealth and total abundance of birds on three key sites in the lower, average and top water-courses Vasyugan are defined. Ornitokompleks of Privasyuganya are presented by not less than 145 types. High total population density and specific richness of birds are characteristic for the selitebnykh, forest and the poluoblesennykh of habitats of Privasyuganya. Positive dependence of population density and a specific variety of birds on degree of heterogeneity of the habitat is tracked. The comparative analysis of the obtained data with landscapes analogs of Ob and its in-flows (Irtysh, Chulym) is made.
