Canadian grizzlies vs. polar bears

Discovery News reports that Canadian grizzly bears are encroaching on polar bear territory.

A Canadian Field Nationalist study shows that the grizzlies are moving into territory in northern Manitoba traditionally thought as polar bear territory. The study claims that this grizzly encroachment could inflict damage on the polar bear population.

Before 1996, there was no evidence that grizzly bears encroached on polar bear territory. From that year on, however, there have been at least 12 sightings, negating the prior theory that the barren landscape north of the Hudson Bay was impassable, in terms of resources, for migrating grizzly bears. But the flexible bears, which can eat everything from meat to berries, have crossed the gap and likely won't look back much, since the polar bear region is known for its abundant caribou, moose, fish and berries.
