Fat Bear Week 2026 Kicks Off
The National Park Service’s single-elimination tournament begins on September 22 and runs through September 29. The champion is announced on the final day of voting.
Background & Context
The contest began in 2014 as a one-day Facebook poll after park ranger Mike Fitz posted before-and-after photos of a bear’s seasonal weight gain. It expanded to a week-long event in 2015 and now draws millions of viewers worldwide. The purpose is to highlight how bears bulk up on the sockeye salmon run to build fat reserves that sustain them through winter torpor.
Contestants Overview
- Bear 32 “Chunk” – defending champion, entered 2025 with a broken jaw and an estimated weight of 1,200 lb.
- Bear 164 “Bucky Dent” – known for positioning near the deepest plunge pool at Brooks Falls.
- Bear 151 “Walker” – veteran male that regularly secures prime fishing spots.
- Bear 903 “Gully” – son of two-time champion 128 Grazer.
- Bear 132 and her three spring cubs – making her Fat Bear Week debut.
- Additional mother-cub families: Bears 284, 610, 806, 901.
- Sub-adults 620 and 694 and single adult females 131, 428, 909, 910 round out the field.
All contestants were selected because they appeared early in the salmon run and returned later, allowing clear before-and-after photographs.
Data & Statistics
- Katmai’s brown bear population exceeds 2,200 individuals; adult males typically weigh 600–900 lb in midsummer and surpass 1,000 lb after the salmon feast.
- More than 1.7 million votes were cast from over 100 countries in the 2025 competition (WLWT).
- Donations to the Katmai Conservancy’s Otis Fund made between September 22 and October 3 will be matched by explore.org (Nypost, Popsci).
On-the-Ground Reports
- July 28 – live cams captured a young cub being killed and eaten by an unrelated mother bear (Bear 806).
- August 2 – a cub of Bear 335 (Jolly) died after climbing a tree with three unrelated cubs, underscoring the harsh realities of bear hierarchy during the salmon run.
Official Statements & Responses
- Park Superintendent Mark Sturm: “There are more cubs at Brooks Camp this year than have been seen in a long time.”
- Mike Fitz on the contest’s origin: “I thought it would be a goofy thing for the rangers.”
Why It Matters
Fat Bear Week spotlights the health of Katmai’s salmon runs, essential for bears’ pre-winter fat accumulation. Conservation groups warn that disruptions to salmon habitat or climate-driven shifts in migration timing could reduce the bears’ ability to build sufficient reserves, threatening their survival and the broader ecosystem.
Conflicting Reports & Gaps
The 2025 vote total is reported as 1.5 million by one source and 1.7 million by another, reflecting a lack of a single verified figure. Precise metrics on how voter demographics influence outcomes remain undocumented.
