Beavers play an important roll as an alternative 食物 来源 in the summer months, in some areas 60% of the wolf's diet is beaver.
One of the most odd part of the diet of 狼 is fish! Biologist Bod Bromley once observed a 狼 in Canada's Northwest Territories catch five 鱼 in fifteen 分钟 in the Talston River.
狼 will also scavenge, In one study of moose carcasses in Algonquin Park, of 30 moose only 4 were killed 由 wolves, the rest died of natural causes.
狼 will also eat wild berries and other 水果 as a minor part of their diet.
