ANTHROPOGENIC INFLUENCES IN THE PERIOD OF LEKKING BEHAVIOR OF WOOD-GROUSE <i>(TETRAO UROGALLUS L.)</i>
The article is based on the results of the author longstanding field research at different wood grouse lekking places in the southern part of the Yenisey Plain. During the wood grouse lekking behavior period anthropogenic factors which influence on the species number are studied. 11 lekking places are revealed and mapped. The research has shown that wood grouse spring hunting with the annual lekking birds shooting can be a reason for their number dramatic decrease. The given examples can be an explanation of such widespread phenomenon as extinction of lekking places as a result of intensive spring hunting on males.
