The brawny bruins on the Alaska Peninsula are ready to brawl it out to see which will win this year’s fattest bear title in the wildly popular annual online voting contest known as Fat Bear Week.
The contest, which began in 2014, is meant to showcase the resiliency of the brown bears, which pack on the pounds each fall to survive the harsh winter by gorging on salmon at Brooks River in remote Katmai National Park and Preserve. People can watch the bears on livestream cameras.
“It really is an opportunity for people to think about how bears survive, what they need to do to survive, what the ecosystem provides them and look at their individual success stories, as well,” said explore.org naturalist Mike Fitz, who started the contest when he was a ranger at Katmai.
This year’s sockeye run has been abundant, so voters can expect some especially corpulent contestants.
Here’s a closer look at the popular online event:
Voters Judge Size by Looks Alone
There are about 2,200 brown bears within Katmai, a 6,562-square-mile (16,997-square-kilometer) park on the Alaska Peninsula, which extends from the state’s southwest corner toward the Aleutian Islands. To be featured in the contest, the bears must frequent the area of the main Brooks Camp.
You can’t get a bear to cooperate and stand on a scale. Weighing the bears would be a dangerous and monumental task, so it’s up to voters to judge size by looks alone. Male brown bears at Katmai weigh about 700 to 900 pounds (318 kg to 408 kg) mid-summer and can bloat to over a 1,000 pounds (454 kg) by September or October, thanks to successful foraging.
A 1,200-pound (544 kg) male bear isn’t unusual at Katmai. Others have been estimated to be about 1,400 pounds (635 kg). Females are about half to two-thirds the size of adult males.
It’s Not All about the Girth
There are factors other than girth to consider, Fitz said. Voters could consider the challenges some contestants have had to overcome, such as the multitasking females who protect their young and produce milk for the cubs while also fattening up for winter themselves.
There’s precedent for a mama bear to take the prize. Grazer, the two-time defending Fat Bear Week champion, beat one of the biggest bears in the Brooks River, Chunk, in last year’s final.
Even though the contest is virtual, the two bears did actually fight it out in the park months earlier. Chunk attacked one of Grazer’s cubs after it fell over a waterfall, an attack that was broadcast live. Grazer fought off Chunk, but the cub later died.
Fan Favorite “Chunk” Adapts to a Newly Broken Jaw
Chunk is back at the park this year but returned to Brooks River in June with a broken jaw, Fitz said. The right side of his jaw is hanging loose and will never heal properly. It probably happened in a fight with another bear. When they attack each other, they target the head and neck, and sometimes they lock jaws. The torque can snap a brown bear’s mandible.
The good news for Chunk is that he’s already adapted to his new disability and it doesn’t seem to have affected his appetite. He remains one of the largest bears on the river.
An Exceptional Salmon Run Means Fatter Bears
Brooks Falls is famous for brown bears snagging salmon out of the air as the fish try to jump upstream to get to their spawning ground.
That didn’t happen much this year, as an exceptional salmon run reduced the need for bears to compete for fishing spots at the falls. “We are kind of expecting really to have some of the fattest bears we’ve ever seen in the event,” Fitz said.
How to vote in Fat Bear Week
The 12 bears selected for the contest — which will be announced today — will be featured in the single-elimination, bracket-style tournament. All voting is done online, so go to www.fatbearweek.org to cast your vote for your favorite Fat Bear!
