Details

Habitat

It inhabits Nearctic forests and mountains. Large woods, thickets, wetland edges, and sometimes food near human settlements are used.

Appearance

Length 120-200 cm; weight 39-280 kg. Fur may be black, brown, cinnamon, or pale, with rounded ears and a short tail. The shoulder hump is less pronounced than in brown bears.

Behavior

Cathemeral and solitary, it shifts activity with season and human pressure. In winter it greatly reduces activity in a den.

Feeding

An omnivore, it eats berries, nuts, grasses, insects, carrion, and small animals. In autumn it seeks energy-rich foods to build fat.

Reproduction

Delayed implantation follows mating, and females give birth in winter dens. Cubs stay with the mother while learning feeding sites and dangers.

Notes

It is listed as Least Concern and is stable in many parts of North America. Garbage and intentional feeding can increase conflict with people.
