Abstract

Observations were made of the foraging activities and consumption rates of three radio-collared coyotes (Canis latrans) during the winter of 1976-1977 in the Chequamegon National Forest of northern Wisconsin. Carrion, mostly white-tailed deer (Odocoileus virginianus), comprised 43% and 69% of the winter diet of a juvenile male and juvenile female coyote, respectively. An adult male coyote killed 88 % of his winter diet. Snowshoe hare (Lepus americanus) comprised nearly 83 % of his diet prior to 15 February. After 15 February, 84% of his diet consisted of deer which he killed. Snow conditions and an increase in coyote sociality may have influenced coyote predation of deer. The three coyotes consumed 10-12% of their body weight per day during most of the winter.
