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.
The park released the following guidelines for recreating in bear country:
Bear spray has proven effective in deterring bears defending cubs and food sources. It can also reduce the number of bears killed by people in self-defense. While firearms are allowed in the park, the discharge of a firearm by visitors is a violation of park regulations.
