Here's why:
* Food Sources: Grizzlies are opportunistic omnivores, and their food sources are often dispersed across a wide area. This makes it difficult for them to live in groups.
* Competition: Groups of grizzly bears would likely compete for food and territory, which is not conducive to their survival.
* Mating Season: While they come together to mate, grizzly bears typically form temporary pairs during this time.
Exceptions:
* Mothers and Cubs: Female grizzly bears live with their cubs for approximately two years, teaching them vital skills for survival.
* Salmon Runs: During peak salmon runs, grizzly bears might congregate in large numbers at rivers and streams. However, they don't necessarily live together in a social structure.
In summary: While grizzly bears might be seen together in certain circumstances, they are primarily solitary animals.
