Fat Bear Week! — LIVE BEAR CAM STREAM

Vote for the fattest bear of the year! Some of the largest brown bears on Earth make their home at Brooks River in Katmai National Park, Alaska. Brown bears get fat to survive and Fat Bear Week is an annual tournament celebrating their success in preparation for winter hibernation. Matchups are open for voting October 2 – 8 between 12 – 9  p.m. Eastern (9 a.m. – 6 p.m. Pacific). See the standings and vote at https://explore.org/fat-bear-week

This is a single elimination tournament. For each match-up, vote for the bear you believe best exemplifies fatness and success in brown bears. The bear with the most votes advances to the next round. Only one will be crowned Fat Bear Week champion. Meet the bears, fill out your bracket, predict your fat bear winner, and campaign for your candidate. 

Why are fat bears important?

Katmai’s brown bears are fattest in late summer and early fall. It is the end-product 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 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.
