Northern brown bears discovered feeding on whitefish runs
Date:9/22/2009

e omnivores and can exist on mostly vegetarian diets, fish are a better food source because they are rich in protein and fat.

Barker says the fall run of whitefish could be playing a significant role in the diets of some Mackenzie Delta brown bears. He would like to see more research conducted on the bears and their feeding habits, in order to mitigate the impacts of development activities.

"Pete's Creek may be an important but spatially concentrated food source, but we can't put it into context until we know more" says Barker. "It could take a small amount of disturbance in an area like this to disrupt these bears. There is still a lot we don't know about Mackenzie Delta bears, and any development should be mindful of such resources."
