I studied the antipredation behavior of the Red-backed Shrike (Lanius collurio) in one breeding season. In random sequence I placed imitation of Eurasian Jay (Garrulus glandarius) in three distances from the Shrike´s nest - 2, 4 and 10 meters. I compared dofferences in Shrikes reactions. I also tested influence of others factors of environment on mobbing intensity - age of breeds, size of clutch, sex, amount of surrounding shrubs and size of nest shru
