Typically, Fat Bear Week is a single-elimination online tournament in which 12 Alaskan brown bears in Brooks River are chosen to compete. Because numerous brown bears are present in the park, narrowing it down to just 12 contestants can be tough.

According to Fitz, the fat week bears are typically chosen by the park rangers based on a variety of factors such as their time of arrival at Brooks River. An early summer arrival at the river ensures that the bear is photographed before and after their weight gain. A compelling storyline is also a driving factor when choosing a contestant. The audience loves to see a veteran bear with skill and resilience competing year after year.

After the bears are picked, the audience keeps voting for their favorite until one bear is left standing. The competition is subjective, says Fitz, and the audience is encouraged to consider many factors when picking a winner, such as how much weight the bear has gained over the last few months and their salmon catch rate. Other factors include sympathizing with the health challenges of older bears or the difficulty of mother bears gaining weight as they cope with the added challenge of fending for their young.

Why Do We Celebrate Fat Bear Week?

For the brown bears in Katmai National Park, which is home to more bears than people, sustenance often includes salmon. Mike Fitz, a former ranger at Katmai and the creator of Fat Bear Week, explains that many of the Fat Bear Week contestants feed on the available salmon at Brooks River between June and October. “Fat Bear Week is an opportunity to think more about a healthy and productive ecosystem that supports the brown bears,” says Fitz.

Fun as the contest is for humans, for the ursine participants of Fat Bear Week, gaining weight is crucial for survival. In order to prepare for hibernation, these omnivorous giants attempt to increase their body mass by eating and drinking nonstop.

During the harsh Alaskan winter, which can last five to eight months, the temperatures are frigid and food is scarce. The bears, of course, lie low in their dens and rely on their own body fat for survival. Gaining weight can also help bears secure mating opportunities and allow the females to support the birth and growth of cubs.

When it comes to their diet, these hefty animals will literally eat just about anything and everything that they can scarf down in the fall months.

Though their primary nourishment comes from nuts, berries, fruits and leaves, bears will also dine on other animals including mammals, reptiles and fish.
