Generally the wolf is a grizzled grey but colour varies
from white to black. The ears are erect and the tail is bushy
and black tipped. The male is larger than the female and average
weight is 55-130 pounds.
The wolf is a very social animal who mates for life and
lives in packs of 2-15. The strongest male is usually the pack
leader; all members of the pack care for the young which helps
unite the pack. An average of 7 pups are born to each female in
April-June. Usually hunting at night, they feed primarily on large
mammals by chasing down their victims either slashing tendons
or driving it back to waiting pack members. Even though they kill
only to survive, studies show that wolves play a key role in drastically
decreasing the number of ungulates, sometimes beyond the rate
of replacement, in any given area. The wolf's only important predator
is man.
