Every fall, just as leaves start to scatter across the country and salmon swim upstream, something remarkable brings people together—from school kids to wildlife enthusiasts. Welcome to Fat Bear Week, the wonderfully quirky, crowd-sourced event that transforms Alaska’s brown bears into global internet phenoms. More than a lighthearted contest, Fat Bear Week is a celebration of nature’s grit, the bears’ resiliency, and the powerful connections we forge with wildlife—often from thousands of miles away.
What is Fat Bear Week All About?
Imagine a bracket tournament—but instead of basketball teams, it’s mighty brown bears vying for the crown of fattest bear. Hosted by Katmai National Park and explore.org, Fat Bear Week offers a front-row seat to the annual ritual of bears bulking up before hibernation. Over the course of just a few months, these incredible animals feast non-stop, aiming to gain as much weight as possible. The public then votes daily on which bear boasts the most impressive transformation, complete with dramatic “before” and “after” pictures.
The Science Behind These Super-Sized Bears
The story of Fat Bear Week is as much about biology as it is about internet fame. As summer gives way to fall, Alaska’s brown bears go into overdrive, devouring salmon by the dozen. This phase—called hyperphagia—pushes them to eat nearly non-stop, preparing their bodies for the long, harsh winter. Without enough calories stored as fat, a bear simply won’t survive until spring. On a good day, a brown bear might munch through 30 fish, absorbing thousands of calories.
Bear binge-eating season in a nutshell:
- Hyperphagia: Nature’s signal to eat constantly and bulk up for the months ahead.
- Protein and Fat: Salmon’s high-fat content is a bear’s best friend.
- Nature’s Toughness: Only the fattest, most prepared bears make it to spring in top form.
