Lynx, Felis lynx, predation on Red Foxes, Vulpes vulpes, Caribou, Rangifer tarandus, and Dall Sheep, Ovis dalli, in Alaska

Abstract

Observations of Canada Lynx (Felis lynx) predation on Red Foxes (Vulpes vulpes) and medium-sized ungulates during winter are reviewed. Characteristics of 13 successful attacks on Red Foxes and 16 cases of predation on Caribou (Rangifer tarandus) and Dall Sheep (Ovis dalli) suggest that Lynx are capable of killing even adults of these species, with foxes being killed most easily. The occurrence of Lynx predation on these relatively large prey appears to be greatest when Snowshoe Hares (Lepus americanus) are scarce.
