(MAMMOTH HOT SPRINGS, WY)– On March 9, Yellowstone National Park biologists working in the northern part of the park reported seeing the first grizzly bear of the spring season. The bear was observed in the backcountry scavenging on a bull bison carcass..
When bears emerge from hibernation, they look for food and often feed on elk and bison that died over the winter. Bears may react aggressively to encounters with people when feeding on carcasses. Male grizzlies come out of hibernation in early March. Females with cubs emerge in April and early May.
All of Yellowstone is grizzly and black bear country: from the deepest backcountry to the boardwalks and parking lots around Old Faithful.
