Fascinating Bear Fact

During the fall, bears are consuming around 20,000 calories per day. An individual acorn has 70–100 calories, which means a bear must eat 200-300 acorns each day to meet its food requirements.

Activity Update

Bears are busy across all elevations of the park devouring whatever food they come across, including late fruit, acorns, and even fish trapped in shrinking pools. Help protect bears by storing your food and scented items (toiletries, drinks, etc.) in a hard-sided building or in a latched food locker. Keeping food within arm’s reach day and night (when not stored properly) also keeps your food from curious bears.

One incident occurred recently at North Pines Campground after visitors accidentally left out drinks in a cooler overnight. The bear knocked the cooler over and bit or clawed open the drinks inside.

Slow Down!

So far this year, 13 bears have been hit by cars along park roads. Help protect wildlife by obeying speed limits and being prepared to stop for animals on roads. A map of bear-hit-by-vehicle hotspots, along with other Yosemite Bear Information, can be viewed at:

Other Wildlife Sightings

Mountain lions have been reported across Yosemite National Park.

Note: A bear incident occurs when a bear causes a monetary loss to a person--that is, if the bear causes property damage or obtains food. Bear incidents also include cases of bears causing injury to a person (which are fairly uncommon).
