- Adult male (or boar) body weight average is 180
kilograms (400 pounds), but in better habitats, body weight can be 325
kilograms (716.5 pounds) or more. Adult female (or sow) body weight
average is about two-thirds that of the male. Adult forefoot print width
is about 14 centimetres (5.5 inches). Adult rear foot print length is
about 25 centimetres (9.75 inches). Colour varies from tawny brown to
black. Fur is often "grizzled" in appearance (silver-tipped) but this is
not true of all grizzlies, nor does this occur at all times of the year.
- In Alberta, grizzly bears are active from
spring until late autumn. As a rule, grizzlies enter dens during a major
snowfall (late October for females, late November for males). Like
northern black bears, grizzlies "hibernate" for the winter, although the
period spent in the winter den averages slightly less and they do
occasionally wake up and roam near the den during the winter.
