Brown Bear (Ursus arctos) Predation of Broad Whitefish (Coregonus nasus) in the Mackenzie Delta Region, Northwest Territories
On 2 October 2007, we observed evidence of at least one brown bear (Ursus arctos) predating and caching broad whitefish (Coregonus nasus) at Pete’s Creek, a tributary of the Mackenzie River, Northwest Territories. While predation on whitefish by brown bears has been reported as traditional ecologica...
