Fat Bear Week is back, and fans can once again vote for Alaska’s chubbiest bear.

The March Madness-style bracket contest is hosted by explore.org and Alaska’s Katmai National Park and Preserve, home to one of the world’s largest populations of brown bears.

Multiple 24-hour live cams provide a front-row seat to watch brown bears gorge on fresh sockeye salmon as they bulk up for winter hibernation.
