The following characteristics of the trophic objects of alpine newt (Triturus alpestris Laur.) have been analyzed: taxon of the trapped prey; the amount of particular taxon from the general amount of prey; frequency of taxon of the preys in stomach contents; size of the prey; origin of trapped prey from aquatic or terrestrial environment; variation of maximum, minimum and medium number of trophic elements per one newt. It was affirmed that foraging behavior of alpine newt is flexible and changes depending on environmental condition and preys presence.
