Prior to Fat Bear Week, researchers at Katmai National Park used Terrestrial Lidar Scanning Technology to determine the “volume” of Katmai’s voluptuous bears. #747 above, had over 27 scans of his belly alone. In the scan above, 747 was standing in shallow water.
747 was the winner of Fat Bear Week, and he topped the Lidar scanning too, coming in at 22.6 cubic feet. Chunk was the second largest bear scanned at 19.78 cubic feet. Walker came in third at 17.7 cubic feet.
Fascinating that the technology is being used on Alaska’s wildlife.
The winner of Katmai’s Fat Bear Week, is Bear #747. The bear that shares a number with a wide-body jet airplane, is the champion of 2020.
747 first appeared on the Brooks River scene in 2004. At that time, the young, male bruin could not maintain prime fishing spots against the other bears. That is no longer the case.
747 is now one of the most dominate bears at Brooks Falls, and he is a talented catcher of salmon. He is not the most aggressive of the bears, but 747 does not have to be. Most bears get out of his way just because of his size. In 2019, 747 was estimated to weigh 1400 pounds. He has attained that weight, if not more, in 2020.
In full disclosure: 747 was my personal favorite for this year’s Fat Bear Week. No attempt was made to influence voters.
There will not be a repeat winner this year in Katmai. Last year’s champ, Holly, lost to eventual finalist Chunk.
Voting starts at 8am ADT on Tuesday for the title. “Wide Body” 747 takes on “Chunk”, Bear #32.
The amount of weight these brown bears put on over the course of the summer is really astounding. The bears enter a state of hyperphagia, which suppresses leptin, which is the chemical in the bears’ body that tells the animal that it is full.
Bears often eat dozens of sockeye salmon at a time, although one especially motivated bear was documented eating 40 salmon in one sitting! Each salmon brings in around 4000 calories.
A bear fishing Brooks River in Katmai can easily gain four pounds a day eating salmon, sedge grasses and berries. As salmon numbers tail off in September, the bears will start to move away from the river and dine elsewhere. Although, stragglers will remain around the Brooks River & Brooks Falls through the month of October.
