SACRAMENTO - In January, when bears are normally hibernating, some are on the prowl.
A bear was sighted in a tree at Yosemite National Park last week. On Friday, a bear hit the slopes at Heavenly Ski Resort.
Temperatures are running about 10 degrees warmer across the region and bears are out looking for food. The warm weather is causing migratory pattern to change for the bears.
According to California Department of Fish and Wildlife spokesman Lt. Patrick Foy, bears hibernate for two reasons: lack of food and winter temperatures.
Foy said after a week of cold temperatures, bears go into hibernation.
"It's reasonable to expect the bears not to hibernate when warmer temps are present," Foy said.
The food source is plentiful in the Lake Tahoe region in the form of garbage and dog food.
Foy said residents need to be more responsible than ever for their garbage.
There have been no reports of bear attacks. Foy said it's best to stay out of the bear's way.
