Chunk, a towering brown bear with a broken jaw, swept the competition Tuesday in the popular Fat Bear Week contest — his first win after narrowly finishing in second place three previous years.

The annual online competition allows viewers to follow 12 bears in Alaska’s Katmai National Park and Preserve on live webcams and cast ballots in a bracket-style, single-elimination tournament that lasts a week. Chunk — known officially as “Bear 32” — beat out Bear 856, who doesn't have a nickname, in the final bracket, according to totals posted on the organizers' website.

Chunk’s weight was estimated at 1,200 pounds by contest organizers, who do not weigh individual bears during the contest due to safety concerns. The bears can gain up to four pounds (1.8 kilograms) per day during summer feeding.

“Despite his broken jaw, he remains one of the biggest, baddest bears at Brooks River,” said Mike Fitz, a naturalist for explore.org. Fitz said Chunk likely hurt his jaw in a fight with another bear.

The contest is wildly popular and this year attracted over 1.5 million votes from fans who watched the ursines gorge on a record run of fall salmon as they fished in the Brooks River about 300 miles (483 kilometers) from Anchorage.

Voters in the online contest could review before and after photos of the bears, lean at the start of summer and fattened at the end. The bears are not actually weighed — that would be too dangerous and difficult — and some fans choose their favorite based on looks or backstory.
