Bear 89, known as "Backpack," has emerged victorious in the 13th annual Fat Bear Week competition organized by the U.S. National Park Service at Katmai National Park in Alaska 1. The brown bear secured 103,344 votes in the final round, surpassing Bear 910, which received 98,253 votes 1. The annual event aims to identify which bears have accumulated the most fat reserves as they prepare for hibernation 1.

A total of 16 bears participated in this year's competition 1. Backpack now faces an extended hibernation period lasting approximately six months, during which bears cease eating and drinking entirely 1. Adult male brown bears typically weigh around 408 kilograms and can add fat equivalent to 25 percent of their body weight by autumn; however, they lose approximately one-third of their mass during the winter hibernation period 1. Notably, Backpack's mother, Holly, won the Fat Bear Week competition in 2019 1.
