Information
Being
an omnivore, a grizzly bear will eat anything--insects,
wild honey, grasses, sedges, roots, mountain sorrel,
buffalo berries, fish, moose, elk, deer, sheep, and
sometimes other bears! The breeding season usually occurs
in June and July, when the bears reach maturity around
five years of age. The male chooses his mate and spends
about a month with her, then leaves to continue his
solitary life. The female then finds or digs her den,
where she will sleep through the winter. She'll give
birth to her cubs in January, February or March. (Gestation
takes four or five months). Average litter size is two,
but four is not uncommon. Weighing less than a pound,
a newborn cub gains weight quickly from the rich mother's
milk containing 33 percent fat. As they grow up, the
cubs may increase their weight as much as 1,000 times.
A deep bond unites a mother with her cubs, and she fiercely
protects them from adult males and other predators,
until they are two years old.
