Interesting site. This is what happens... one book or one site gives numbers. Then dozens of other books or sites copy. What we really need is an actual study where bears are actually weighed with sex and age given. One reason I see this as mere estimation is 1000 pounds is a very round number. Seldom will you average out multiple weights and end up with such a round number. If it has read 989-pounds or 1,042-pounds, then I might have been a believer.  |

You are right that probably one site copies the other one and so on. And yes, be happy because if you read good, wiki does not state exactly 1000 lbs, it states the average for mature males is “1052 to 1177 lbs”
The size range for females (sows) is from 181 to 318 kg (399 to 701 lb), and for males (boars), it is 272 to 635 kg (600 to 1,400 lb).[2][6] Mature males average 477–534 kg (1,052–1,177 lb) over the course of the year,[7] and can weigh up to 680 kg (1,500 lb) at peak times. Females are typically about 20% smaller and 30% lighter than males,[2] and adult sizes are attained when they are 6 years old. Bears weigh the least when they emerge from their dens in the spring, and can increase their weight by 20–30%[6] during late summer and fall. Captive bears can sometimes attain weights that are considerably greater than those of their counterparts in the wilderness.

shaggygod.proboards.com/ Urus arctos says: Interesting to see how the "312 kg" average figure often cited for Kodiak bears brakes down (note that the average weight of the 10 bears in the 6-7 year old and older categories have an average weight of 312 kg). An older, reproductive, male likely weighs substantially more (at least 835 lb). Grrraaahhh says: Post by grrraaahhh on Jul 27, 2012 at 10:07am RE: 312 kg figure. There are a handful of popular data tables people cite when it comes to North American brown & grizzly bear morphometry including weight. IMO, a comprehensive review of these data tables are called for hence the creation of the following thread. Some of the corresponding data have already been posted (see Extant/North America section) while more will be forthcoming. Getting back to Kodiak brown bears, from the Kodiak National Wildlife Refuge Center, the figure of 600-1,400 lbs for male bears is easier understood. The lower range numbers correspond to young adult male Kodiak bears while the higher numbers correspond to the older mature bears. Regrettably, the data for older "trophy" size bears is thin (in my experience, this is true for many bear populations) where such data can be found would be from hunting literature sources but outside of skull measurements; finding out other morphometrical info (e.g, weight, chest girth, body length, paw size, etc) is challenging. Nonetheless, after reviewing a lot of the technical literature, the quote of the "half-ton" Kodiak bear are common is accurate. Anecdotal observation, when I am watching tourist video (e.g., Youtube) or viewing photograph of mature Kodiak brown bears (less online material) and mature SW Peninsula brown bears (a lot more online sources), I see a lot of males pushing and exceeding half-ton weight & size. Post by grrraaahhh on Jul 27, 2012 at 3:38pm From the Kodiak Brown Bear Center: Kodiak bears are the biggest bear in the world? True. Since we are Kodiak bear biologists, we consider this true- however, in reality it may be a draw with polar bears. The largest bears are measured using three primary criteria: weight, overall length, and skull size. Adult male Kodiak bears and adult male polar bears reach similar weights, though exact numbers are hard to come by due to the logistics and difficulties of weighing an animal close to a ton in a remote location. The largest male Kodiak bear weighed approximately 1,500 pounds, and this is an often-quoted figure for the largest adult male polar bear as well. We will call this a draw. In terms of overall length, polar bears likely have a slight edge over an equivalent Kodiak bear because they tend to be more slender and streamlined to aid with their swimming. Kodiak bears are more stocky and robust. With skull sizes (length + width), Kodiak bears are the clear winners. The largest (living) bears ever recorded have been Kodiak bears, and they even give the largest extinct bears (cave bears and short-faced bears) a run for their money in terms of skull size. The largest polar bear? It comes up on #20 on the list dominated by Kodiaks. Kodiak bears are the largest terrestrial omnivore in the world? True. A large male can stand over 10’ tall on its hind legs, 5’ at the shoulder when on all four legs, and weigh as much as 1,500 pounds before hibernation. Adult females are smaller, but can still weigh up to 900 pounds before hibernation. Polar bears are considered marine mammals because the majority of their lives are spent on sea ice, and thus are excluded fr

So what are our conclusions here? We have a very old chart from 1969 which says the average is 835 lbs. we have wiki that states that is 1052 lbs, all the other sites state about 1000 lbs. my myself, i believe its closer to 1000, i go with that. 9 year olds +.

But having a figure from an actual study would be better. Then it could not be disputed. |

Are these weight estimates for the bear also taken at maximum body condition, for over-wintering?
If so, bear in mind, ~40% of that mass - is just fat.

Sure, they need to pack it on to survive the winter, but its still just fat, not muscle mass.

Yeah, try telling that to any coach/trainer of real athletes.
Poseur bodybuilders are exercising merely for showing off, not for actual sporting achievement.
Fat is a liability for combat athletics, its a simple matter of physics, see: 'inertia'.

You take a big man, like Mark Henry or Braun Strowman and ( in a real fight ) your athlete would fall. Bottom line; it has been proven that a lion cannot kill a grizzly. Just as in the R.F.E., no tiger has ever killed a mature male grizzly. It just doesn't happen.
Note: the topic here is SIZE and that means bear size.

Fat is a liability for combat athletics, its a simple matter of physics, see: 'inertia'. Not a liability for guys like Fedor Emelianenko (it might have even helped him) and other very successful heavier-side heavyweight MMA fighters (Cormier, Nelson, etc...), unless it is excess amount of fat. Bears are astonishingly fast for even 50% body fat while us humans would become slugs if we were to have that amount of fat percentage. Bears are adapted to maintaining heavy loads of weight in general (muscle or fat), and just simply seem to break physical limitations at any given opportunity. |

Not to mention that the ketogenic way of fueling one's body also lowers the susceptibility to auto-immune diseases (Celiac's and other harmful kidney-related diseases) and metabolic conditions. Humans, even across global cultures (save Polynesians and some African tribes), relied in healthy fat sources for most of their nutrition. All-in-all, fat is quite healthy for any animal. |

Fat is good ESPECIALLY for bears. Not to mention the Polar bear.

I could be wrong about this. But when a bear gain weight don't the overall muscles get bigger as well?
