The bank vole Clethrionomys glareolus (Schreb.) is the most common prey animal. Also frog are rathter frequently consumed. The calculated consumption is 349.8 kcal per adult individual per year, or 25 rodents, 6 frogs and few animals from other systematic groups. As the density of vipers in the study area was one individual per hectar, the impact of this predator on rodent population seems to be insignificant.
