Abstract

The diet of the American mink near the lakes and mountain rivers of the Southern Urals was studied. The structure and dynamics of the minks’ feeding near the lakes and mountain rivers differed significantly. On mountain rivers the minks’ diet depended on the abundance of small mammals on the river bank. The abundance of small mammals in each season was determined by the peculiarities of the hydrological regime.
