First Yellowstone grizzly bear emerges from hibernation

Biologists with Yellowstone National Park reported seeing the first grizzly bear of the spring season on Monday, according to a National Park Service press release.

The griz was seen in the northern part of the park scavenging on a bull bison carcass in the backcountry.

Most male grizzlies emerge from hibernation in early March, while females with cubs emerge in April and early May.

Park officials said that bears emerging from hibernation look for food and often scavenge on elk and bison that died over the winter. Bears may act aggressively to encounters with people while feeding, and visitors are cautioned to always be bear aware.
