Description

Behaviour

The life of a Grizzly Bear revolves around an intensive search for the most nutrient-rich foods it can find.  It will spend October through April in a winter den, before emerging in spring to search for food. Yukon Grizzly Bears have a very low rate of reproduction.  They breed for the first time in their eighth year and only reproduce every three to four years. Often they are not successful with their first litters.

Diet

Varies by region based on food available in the area. Includes roots, berries, grasses, sedges, horsetails, moose, caribou, and small mammals.
