Brown bears in Katmai National Park, Alaska, are competing in the annual Fat Bear Week contest, which highlights their efforts to fatten up by feasting on salmon before winter hibernation. This year’s competition features 16 bears, a record number, and includes new contenders like male bear Backpack (Bear 89) and dominant male 151 Walker. The single-elimination tournament begins on September 22 with public voting, culminating in a champion crowned on September 29. Last year’s winner, Bear 32 nicknamed "Chunk," weighing over 1,200 pounds, is among the competitors again this year.
