New Research On Wolf Diets

NPR reports

New research on wolf packs at Voyageurs National Park in northern Minnesota is challenging the conventional wisdom on wolves: Their diets are a lot more varied than scientists previously thought.

Among their major findings, so far:

  • Wolves are omnivores. They eat a lot of blueberries in July and August. By the time the fruit ripens in northern Minnesota, deer fawns — wolves’ primary prey in June — are old enough to escape them.
  • Wolves eat beavers — a lot of them. Beaver can constitute up to 42 percent of a pack’s diet from April until October, researchers have found. Preliminary data show that, on average, one wolf in Voyageurs kills about six to eight beavers per year. But that varies. Individual wolves might not eat any beavers at all. But they found one wolf that had eaten 28 beavers in one year.
  • Wolves hunt beaver differently than they do other prey. Instead of chasing them, they lie in ambush, and strike when the beaver venture onto land.
  • Wolves are good swimmers. One collared wolf swam 12 times across sections of Rainy Lake over a two-day period, covering 2.6 miles.
