Online voting has opened for Fat Bear Week, the quirky annual tournament that pits Alaska's brown bears against one another in a contest of sheer bulk. The event, now in its twelfth year, invites wildlife enthusiasts worldwide to pick the bear they think has done the best job of packing on pounds before the long winter sleep.
Sixteen bears are in the running this year, including last year's victor, Chunk (officially Bear 32), who tipped the scales at a reported 544 kilograms when he took the title. The competition runs through to the final round on Tuesday, 29 September, when the public will crown this year's champion.
Mike Fitz, a resident naturalist at Explore.org, told the Associated Press that the contest is more than a celebration of size—it highlights the bears' remarkable survival strategy. Because they do not eat during hibernation, they must consume enough food in roughly six months to sustain themselves for the entire year.
But choosing a winner is not simply a matter of identifying the heaviest bear. Fitz noted that this year's field is particularly unpredictable: "There's a few bears that are larger than others, but it's not necessarily about body mass alone. We want people to consider the bears' stories as well, because getting fat means different for a big adult male who's maybe trying to dominate access to the best fishing spots at Brooks Falls."
Why getting fat is essential for survival
Katmai National Park and Preserve is home to roughly 2,200 brown bears. The competition, which began in 2014, was designed to raise public awareness of these animals and their extraordinary preparations for winter. Adult male brown bears typically weigh between 270 and 410 kilograms, though particularly large males can exceed 450 kilograms after feasting on salmon. Females are generally about one-third smaller.
During hibernation, bears neither eat nor drink and can lose around a third of their body weight. Fitz also stressed the importance of healthy salmon populations to the bears' survival, pointing to the abundant sockeye salmon runs in Alaska's Bristol Bay region as an example of what thriving river ecosystems can support. He argued that this demonstrates why protecting and restoring salmon populations elsewhere in North America is so vital, especially where numbers are declining.
Beyond the spectacle of size, the competition offers a window into the bears' daily lives. Fitz described how viewers can observe everything from successful fishing sessions and playful interactions to the hardships faced by mothers trying to feed their cubs or coping with the loss of their young. "We get to see their joys when they have a belly full of fish, we get to see them having fun when they're playing with another bear in a friendly manner and we get to see the real hardships that they experience—the mother struggling to feed their cubs, the mothers who maybe lose cubs for instance," he said.
While Fat Bear Week is a distinctly Alaskan affair, its appeal resonates far beyond the state's borders. For Europeans, the contest offers a lighthearted yet meaningful reminder of the delicate balance between wildlife and ecosystems—a theme that echoes in conservation efforts across the continent, from the Balkans' bear populations to the rewilding initiatives in the Carpathians. As Fitz noted, the bears' fate is tied to the health of their environment, a lesson that transcends geography.
As the tournament progresses, fans can follow the action on the park's webcams and cast their votes online. Whether Chunk retains his crown or a new contender emerges, the real winner is the public's understanding of these magnificent creatures and the challenges they face.
