After a monthslong winter hibernation, Yellowstone National Park just saw its first grizzly bear of 2026 wandering wide awake.

Yellowstone biologists spotted the grizzly Monday as it chowed down on a bull bison carcass in the park’s northern backcountry. The sighting of the bear came on a similar timeline as in years past.

All of the park’s first spring observations of grizzlies having fallen in early March since 2022, according to a news release.
