Mirror, mirror on the wall, who’s the fattest of them all? Don’t worry, Disney princesses aren’t included in this query — the contenders seeking to be crowned the chubbiest are larger, furrier, and competing in this year’s Fat Bear Week.

The beloved contest playfully pits the brown bears of Alaska’s Katmai National Park and Preserve against each other to celebrate how well the mammals bulk up for winter hibernation. Taking place through Tuesday, Sept. 30, the single-elimination tournament encourages voters to choose the animal they believe best “exemplifies fatness and success in brown bears.”

Aside from providing sustenance during hibernation, body fat is important for adult female bears that give birth in mid-winter and must nurse their cubs without eating while the young ones remain in the den until spring. Adult males, on the other hand, need the extra bulk to challenge competitors, and juveniles require proper nourishment for their rapidly growing bodies. At Katmai, bears feast on salmon and other food from late June to mid-October, fetching their fare from one of the “largest, healthiest runs of sockeye salmon left on the planet.” 

The U.S. National Park Service, or NPS, announced this year’s competition Sept. 4 by highlighting last year’s winners. In first place for 2024 was 128 Grazer, a mother bear who successfully defended her title for the second consecutive year. She received over 71,000 votes, more than double the votes of her closest rival, a male named Chunk.

“Big, bold, and bear-y round: A fat bear champ will soon be crowned!” NPS wrote in a Facebook post. “Brace yourselves, bear buffs! #FatBearWeek, the ultimate bracket competition where the public votes for the bear that achieves peak spherical status, is just around the corner!” 

Prior to the main event, a “chubby cubby appetizer” — Fat Bear Junior — was held for voters to select which cub they wanted to see compete with the adults for the winning title. This year’s victor was 128 Grazer’s Yearling, nicknamed “128 Jr.” or “Biggie.” 

NPS added: “From tubby titans to gargantuan gluttons, get ready to cheer for the heftiest bears in Katmai National Park and Preserve’s Brooks River!”
