Wolverines will eat just about any form of meat that comes their way. They hunt small mammals including rodents and rabbits, birds and bird eggs, insects, and are ardent scavengers of carrion. Wolverines have been reported to be able to pull down larger mammals such as caribou, but predation on large mammals is probably not common. Wolverines are generally solitary predators except during the breeding season when pairs may travel together. They are active both during the day and at night.
Wolverines are notorious scavengers and thieves.
In older days Wolverines used to follow trap lines, steal the bait or prey in the traps, destroy the traps, and hide the pieces. They did not endear themselves to trappers. There are many stories of Wolverines breaking into cabins and stealing every plate, pot, knife, and kettle and hiding the loot in the woods. The Wolverine is said to be very intelligent and ferocious in defense of itself and its young. Young are born between February and April in a den dug in the snow.
