Lone Wolf, Canis lupus, Displaced from a Kill by an Adult Black Bear, Ursus americanus, in Northeastern Alberta

Mark Fremmerlid, A. David M. Latham

Abstract


Wolf (Canis lupus) packs are generally competitively dominant over Black Bears (Ursus americanus); however, less is known about lone Wolf-Black Bear interactions. We report an observation of a lone Wolf and an adult Black Bear at a kill made by the Wolf in northeastern Alberta. In this instance, the bear chased the Wolf from the kill site. Our observation supports the hypothesis that Wolf-Black Bear interactions may fit the pattern of asymmetrical interference competition when the interaction involves a lone Wolf rather than a pack.
