A bear may stand on its hind legs to get a better look or to pick up your scent if it cannot tell what you are.
Grizzlies tend to like open areas like tundra, alpine meadows and coastlines. For the most part, grizzly bears live alone. Every now and then, they will meet up with other grizzlies outside of mating season and stand next to each other, but not much socialization will occur.
Grizzlies have a habit of rubbing their backs against trees, but they’re not trying to scratch an unbearable itch. Rather, they are communicating with one another by leaving their scent. One scientist who studied bears rubbing their backs in the woods says that by marking trees, male bears get to know one another better, thus reducing fighting among themselves over females.
The biggest gathering of grizzlies is during the salmon run in Alaska. When the salmon migrate upstream for the summer, grizzlies gather to catch their fill of these bountiful fish, according to National Geographic. The largest bears get the first catch.
The fat in salmon help grizzlies bulk up for hibernation in the winter. Before hibernation, these bears will dig dens in hillsides and may line the floor with a bed of leaves. Hibernation lasts four to six months, which can add up to one-third to one-half of their life, according to the San Diego Zoo.
Grizzlies like to spend their days awake and hunting, but if humans are around they have been known to switch to a nightly schedule. Most brown bears are most active during early morning and dusk.
