Backpack, the Gentle Giant, Claims Alaska’s Fat Bear Week Crown

A peaceful brown bear with a famous mother has been crowned the champion of Alaska’s Fat Bear Week, defeating a formidable rival in a closely watched online poll that celebrates the annual preparations of the region’s most famous ursine residents before winter.

Backpack, officially known as Bear 89, was declared the winner on Tuesday evening after receiving more than 100,000 votes, according to the nonprofit organisation that runs the long-standing competition. The contest, now in its 12th year, is held in Katmai National Park and Preserve on the Alaska Peninsula, a vast wilderness area that is home to approximately 2,200 brown bears.

The final result was tight. Backpack secured just over 50 percent of the vote, narrowly edging out Bear 910, who had also advanced deep into the bracket. The outcome was announced after the final online poll closed, capping a week of enthusiastic public participation.

Fat Bear Week was first launched in 2014 as an interactive way to teach people about brown bears, the coastal relatives of grizzlies. Since then, it has grown into a global internet phenomenon, drawing hundreds of thousands of voters who follow the animals via live cameras positioned along the Brooks River.

This year’s edition featured 16 bears competing in a single-elimination, bracket-style tournament. Members of the public watched the bears on explore.org’s livestreams before casting their ballots online, turning the event into a blend of wildlife documentary and friendly competition.

Backpack’s victory is notable not only for his size but for his temperament. The nonprofit’s contestant profile describes him as a bear that has not displayed much aggression toward rivals, a trait that sets him apart from many large adult males. Instead of brawling, he relies on what the profile calls “quiet strength,” and he is frequently spotted on wildlife cameras sitting on a rock downstream, seemingly taking in the scenery around him.

His background adds a layer of narrative appeal. Backpack is the son of Holly, a former Fat Bear Week champion who first introduced him to the Brooks River in 2006, when he was a first-year cub. His name comes from his habit of climbing onto his mother’s back while the pair swam across the river. Fans on social media cheered him on, noting both his lineage and his reputation as a gentle giant.

To reach the title, Backpack had to get past Bucky, who had earlier knocked out last year’s winner, Chunk. Chunk, officially Bear 32, had claimed victory in the previous year at an estimated 1,200 pounds, but his reign ended in the first round this time. Bucky then fell to Backpack in a later face-off, clearing the path to the final.

In the championship round, Backpack faced Bear 910, who is also the daughter of a former champion, 409 Beadnose. The matchup gave the final a distinct family theme, with two bears carrying on the legacies of past winners.

The contest’s underlying purpose is serious. Fat Bear Week highlights the resilience of the brown bears that live in the preserve, which stretches from Alaska’s southwestern corner toward the Aleutian Islands. The animals must pile on enormous amounts of weight to survive the harsh winter, when food becomes scarce and conditions turn brutal.

The bears gather along the Brooks River to feast on salmon that return there starting in late June. For months, they gorge themselves on the abundant fish, accumulating the fat reserves they need to endure hibernation. The nonprofit’s website puts it simply: “Fat bears are successful bears.” To qualify for the contest, a bear must regularly frequent the area around the river.

The physical transformation is striking. Adult male brown bears typically weigh between 600 and 900 pounds, or roughly 270 to 410 kilograms, in midsummer. By the time they are ready to hibernate, after feeding on migrating and spawning salmon, large males can exceed 1,000 pounds, or 454 kilograms. Females are about one-third smaller. Bears may each consume as many as 30 fish a day during this period, effectively cramming a year’s worth of eating into about six months.

Winter hibernation imposes a heavy toll. Bears do not eat or drink during this period and can lose up to one-third of their body weight. The bears that appear fattest in the autumn are therefore the ones best positioned to emerge healthy in the spring.

This year’s competition also reflected a notable development at the river: a record-high number of bear families and cubs. Five bear families were included among the contestants, a recognition of the unusual abundance of mothers and young. For a mother bear, the challenge is especially demanding. She must feed and protect her cubs while also consuming enough calories to sustain herself through hibernation. Cubs face constant risks, including attacks from other bears driven by territorial instincts or food scarcity.

One family that captured attention was that of Bear 132, who advanced to the semifinals with her three spring cubs before losing to Bear 910. Bear 132 is described in her contestant profile as one of the largest and most experienced mother bears at Brooks River. Her summer included a tense episode in mid-July, when one of her cubs became separated from the family and wandered the river corridor alone for several days. The cub was eventually reunited with its mother and siblings.

The event’s combination of drama, wildlife biology and online participation has helped it build a devoted following far beyond Alaska. Voters are drawn not only to the spectacle of enormous bears but also to the individual stories behind each animal, from family lineages to survival struggles.

For Katmai National Park, the attention serves a broader educational purpose. By turning the bears into recognizable characters with names and histories, organisers hope to foster public interest in conservation and in the delicate ecosystems the animals depend on. The salmon runs of the Brooks River are central to that system, linking the health of the bear population to the broader natural cycles of the region.

Backpack’s win adds another chapter to that story. A bear known for avoiding conflict and for his connection to a former champion, he now holds the title of the heftiest bear in the preserve for a year. His victory, decided by a razor-thin margin, underscores how competitive the contest has become and how closely the public follows the fortunes of the animals.

As winter approaches and the bears retreat to their dens, the focus will shift from online polls to the quiet test of survival. The fat accumulated along the Brooks River will determine which bears emerge next spring. For now, Backpack stands as the season’s most celebrated example of a simple truth: in the Alaskan wilderness, bulk is not just impressive, it is essential.
