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.
Starting Tuesday and running until Sept. 30, the public can visit www.fatbearweek.org to see before-and-after photos of the fattening bears and vote in head-to-head matchups that will eventually lead to the crowning of a champion.
