For grizzly bears and wolves in Yellowstone, competing for food has unexpected results

Sharing a meal with a greedy tablemate makes for fraught relations, especially when there are claws and fangs involved.

For wolves and grizzly bears in Yellowstone National Park, competition over a dead elk dinner has some unexpected results. When a bear steals a meal from a wolf pack, the wolves kill less often.

"What we did was break down the wolf foraging sequence," University of Montana researcher Matthew Metz told the Missoulian. "We studied their searching time and their handling time - the amount of time they spend eating and digesting their kills."
