Wolverines are widely distributed in the northern reaches of both hemispheres. In North America, they occupy remote habitats from the high mountainous interior of the Rockies to Arctic coastal tundra. They are solitary wanderers who specialize on larger vertebrate prey. They usually feed on small-to-medium size mammals, but have even been known to take down caribou, and will eat carrion. Wolverines use large home ranges of 100 to 600 square km. Males are larger than females, and their ranges are larger; a male will exclude all other males from his range, but his territory may overlap with that of several females.
