Welcome to Fat Bear Week 2023! Katmai National Park and Preserve’s brown bears spent the summer gorging on 4,500-calorie salmon, and they've transformed into rotund giants, some over 1,000 pounds. The Alaskan park is holding its annual playoff-like competition for the fattest of the fat bears (you can vote online between Oct.4 through Oct. 10). Mashable will be following all the ursine activity.


They're back.

The wildlife streamers explore.org officially turned on the Alaskan brown bear cams on Monday, June 14. The cameras, situated along the salmon-rich Brooks River in Katmai National Park and Preserve, film the internet-famous bears fishing, fighting, sleeping, playing, and beyond throughout the summer and fall.

Bear activity usually ramps up in July, when salmon begin migrating up the river. Here's what to expect when tuning into the bear cams, which are beamed from a remote, mostly roadless part of Alaska, to people globally:

  1. July: The salmon run up the Brooks River kicks off in early July, and the bears start to congregate at the river to devour fat, 4,500-calorie sockeye salmon. It's an exciting, phenomenal scene.

  2. August: Often the Brooks River and bear cams quiet down in August, as the bears leave to capitalize on other fishing opportunities (the Brooks River salmon run can dwindle by late July). Though during the big salmon run years of late, many bears still stick around, even in August.

  3. September: The bears, now often filled-out and rotund, return to the Brooks River (and bear cams) in great numbers to feast on dead and dying salmon. The winter looms large.

  4. October: The bears continue to eat and start to hibernate. The park holds its annual Fat Bear Week contest, which celebrates the wildness and success of the impressively fat bears.

  5. November: The callous Alaskan winter sets in, and the bears hibernate until early spring. The solar-powered bear cams, running low on sunlight, stop transmitting.

The bear cams bring many intriguing 2021 storylines:

There are five cameras mounted along the relatively short, 1.5-mile Brooks River (and one underwater). We'll be watching. Will you?
