Winter Habitat Selection and Feeding-Habits of Polecats (Mustela-Putorius) in the Bialowieza National-Park, Poland. Jedrzejewski, W., Jedrzejewska, B., & Brzezinski, M. Zeitschrift Fur Saugetierkunde-International Journal of Mammalian Biology, 58(2):75-83, 1993. abstract bibtex Polecats (Mustela putorius), that inhabited the pristine mature forests, were studied by means of snowtracking on 11.2 km2 during 5 winters (1985/86-88/89 and 1990/91). They preferred wet habitats: riverside ash-alder forests and bog alderwoods. Drier forests (oak-linden-hornbeam and spruce-pine stands) were used by polecats less frequently than would have been expected from their occurrence in the study area. The intensity of polecats' use of habitats changed with winter weather. On relatively warm days (0 to -5-degrees-C ) polecat tracks were recorded twice as often in wet forests as in the dry ones. At temperatures from -6 to -10-degrees-C, this ratio approached 1:1, and below -10-degrees-C, when most of the running and stagnant waters were frozen, polecat tracks were found in drier forests twice as frequently as in wet forests. The diet of polecats was studied by an analysis of 222 scats collected during 5 winters (1986/87-1990/91). Anurans (mainly Rana temporaria) comprised 70 to 98% of the biomass consumed by polecats and were found in 60 to 95% of scats. Forest rodents (Apodemus flavicollis and Clethrionomys glareolus) constituted from 1 to 29% of the biomass eaten by polecats. The consumption of rodents grew with decreasing winter temperature and increasing numbers of rodents. Snowtracking of individual polecats showed that in wet forests, the polecats moved in close proximity to water courses and searched for anurans, whereas in the drier forests, they hunted rodents, mainly by digging.
