Fat Bear Week has returned to Alaska’s Katmai National Park, marking the 12th annual celebration of the park’s brown bears as they prepare for winter hibernation. This quirky event, which runs through September 29, invites the public to vote for their favorite bear based on its size and fat reserves. The competition highlights the bears’ natural behavior of consuming large amounts of food—up to 200,000 calories a day—to build the energy stores needed for months of hibernation. This year, defending champion Chunk 32, a massive brown bear weighing around 1,200 pounds, has returned to the competition despite suffering severe jaw injuries last year. His recovery and continued dominance have made him a fan favorite, demonstrating the resilience of these animals in the wild. Chunk 32’s presence adds an extra layer of excitement to the event, as visitors and online viewers alike watch him compete against other bears vying for the title. Fat Bear Week was founded in 2014 by a former park ranger as a lighthearted way to engage the public with the park’s wildlife. What began as a small local event has since grown into an international phenomenon, drawing over 1.7 million votes in the previous year. The competition is structured as a single-elimination tournament, where bears are judged on their weight and overall health, with the winner declared the “Fat Bear of the Year.” Katmai National Park is home to an estimated 2,200 brown bears, making it one of the most bear-dense areas in the world. The event not only entertains but also raises awareness about the importance of preserving these animals’ habitats. As the voting continues, fans around the world eagerly await the results, celebrating the bears’ natural instincts and the unique way Katmai National Park connects people with the wilderness.
