A total 67 samples with 3,211 prey items were analysed. common dormouse (Muscardinus avellanarius) comprised 2.0% by numbers and 1.4% biomass consumed. difference between 2.3-fold 2.6-fold, accordingly. It is obvious that this species not a primary prey, but 15 mammals 30 bird represented exceeding M. avellanarius. Thus, we do consider avellanarius among rarest items.
