Beavers play an important roll as an alternative food bron 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 wolves is fish! Biologist Bod Bromley once observed a wolf in Canada's Northwest Territories catch five vis in fifteen minuten in the Talston River.
Wolves will also scavenge, In one study of moose carcasses in Algonquin Park, of 30 moose only 4 were killed door wolves, the rest died of natural causes.
Wolves will also eat wild berries and other fruit as a minor part of their diet.
