Brown bears survive by using their adaptability when circumstances change, remaining resilient when situations become difficult, following their instincts, and relying on their intelligence when facing new challenges.
Get to know the bears of Fat Bear Week on our Meet the Bears page and learn about how they survive in the wildlands of Katmai National Park, Alaska, home to some of the last great runs of salmon on earth.
Who should I vote for?
Although getting fat enough to survive winter hibernation is the goal, success for Katmai National Park’s brown bears is measured in many ways. How did the bears overcome the challenges that they faced this summer? How might their hard work lead to their success next year? How big did they really get?
Mother bears need ample body fat to survive hibernation, but they also must feed, nurture, and protect their cubs. Single adult females get fat in preparation to give birth to cubs in mid winter and nurse them without eating until they exit the den in spring. Older bears get fat while trying to compete with younger bears for preferred fishing spots. Large adult male bears maintain their high rank in the hierarchy by challenging competitors. Cubs and subadult (teenage) bears grow proportionally more each year than even the biggest adults, while they learn the skills to survive. In short, Fat Bear Week is a subjective competition.

Why are fat bears important?
Katmai’s brown bears are fattest in late summer and early fall. It is the result of a summer-long effort to satisfy their profound hunger and prepare for winter hibernation. During hibernation, bears do not eat or drink and lose one-third of their body weight. Their winter survival depends on accumulating ample fat reserves before entering the den.
To get fat, bears gorge on the richest and most accessible foods they can find. In Katmai National Park that often means salmon. Dozens of bears gather at Brooks River to feast on salmon from late June until mid October. Perhaps no other river on Earth offers bears the chance to feed on salmon at one place for so long.
Fat bears are successful bears. They exemplify the richness of Katmai National Park and Bristol Bay, Alaska, a wild region that is home to more brown bears than people and the largest, healthiest runs of sockeye salmon left on the planet.
