WAPITI, Wyo. (AP) — Wildlife officials say they are getting reports of grizzly bear sightings at lower elevations east of Yellowstone National Park.

In response, the Shoshone and Bridger-Teton national forests have placed food storage regulations into effect.

Forest Service wildlife biologist Andy Pills tells The Billings Gazette (http://bit.ly/ylM1MT ) that adult male grizzly bears typically start to show activity this time of year.

Females with cubs don't generally emerge until late April or early May.
