Abstract

We identified the stomach contents of fishers (Martes pennanti) collected during winter between 1989 and 1993 from throughout British Columbia. Eighteen types of mammalian and avian prey were found in 256 stomachs. The most commonly occurring species of prey were snowshoe hares (Lepus americanus), red squirrels (Tamiasciurus hudsonicus), and southern red-backed voles (Clethrionomys gapperi). The diets of fishers varied between sexes; female fishers consumed small prey more frequently than did males. This difference in diets is likely related to the extreme sexual dimorphism of fishers and perhaps differences in habitats where males and females forage. The composition and breadth of the winter diets have implications for understanding habitat relationships of fishers.
