River Otter (Lontra canadensis) Killed by Wolves (Canis lupus) during Winter in Northern Minnesota

Thomas D. Gable, Steve K. Windels, Ian C. Rautio


Few accounts exist of Gray Wolves (Canis lupus) killing small sympatric mammalian predators. In January 2017, we observed a River Otter (Lontra canadensis) that had been killed by wolves on the ice in Voyageurs National Park, Minnesota. This is one of only a few documented instances of wolves killing otters.
