University of Minnesota Project: Study Wolf Habitat

Most people think of wolves as predators that only kill large mammals like moose and deer, but new UMN research published in Mammalian Biology shows that wolves are highly adaptable predators capable of finding unique food sources. In this case, documented in detail for the first time: freshwater fish.

Researchers from the Voyageurs Wolf Project, a collaboration between the University of Minnesota and Voyageurs National Park, made the initial observation and captured rare video footage of wolves hunting freshwater fish near the park.

Using GPS collars, the research team collects location data from wolves in over seven packs every 20 minutes. This enables them to determine pack territory and predation behaviors in and just to the south of the park (also known as the Greater Voyageurs Ecosystem) which is runs along the Minnesota-Ontario border. In April 2017, UMN Ph.D. candidate Tom Gable hiked to a creek to check on an area where one of the collared wolves had spent a lot of time.
