An environmental group says a bear that should be hibernating is eating spilled grain instead.

Jim Pissot is with Defenders of Wildlife.

He has taken pictures of a large grizzly bear roaming the area in Banff National Park near Lake Louise.

The photos were taken December 2nd and Pissot says it is evidence that the bear's natural instincts are being altered.

"We suspect, and bear biologists concur, that this bear is staying alive because he's attracted to grain on the tracks."

Canadian Pacific Railway says the company is spending 23 million dollars to fix its grain cars to stop spillage.
