Considering what attributes provide the grizzly with his incredible survival skills.
1 - Intelligence. Brain-power cannot be accurately measured. This is not an exact science. But both field studies lad studies as well as information from animal trainers support that bears rank high in intelligence. Probably on a similar level with the elephants and great apes. 2 - Strength and Leverage. The measuring of strength and leverage is not an exact science. Some people's idea of comparing strength is according to how much the animal can lift, drag, or carry as compared to his own weight. I strongly disagree. Muscle and bone have weight. Also, the build of the animal provides strength and leverage. Who is the strongest according to equal head-and-body length is the fair way to compare two mammals standing on four feet. Some experts claim that no land-based animal the size of a bear is as strong. I will add to this that no bear is pound-for-pound as strong as a grizzly. This due to his shoulder hump-of-muscle which reinfoeces his enormous upper-body strength. 3 - Fighting Ability - From the time a grizzly is a cute little teddy bear in his mother's den, he is wrestling with his siblings. A bear is a natural-born wrestler. A full-grown grizzly is a mauler and a brawler who can tear a lion or a tiger to pieces. Just as each grizzly develops his own unique fishing technique, a grizzly has no set rules dictating his fighting and killing techniques. 4 - Diet - Bears are omnivores. Those animals which have the greater range of food choices have the greater chance of survival when things become difficult. Thus in Africa, Asia, Europe, and N.America the brown bear survived the Pleistocene Ice Age. 5 - Senses - A bear has comparatively poor eye-site. The measuring of eye-site is not an exact science. The eye-site of a bear might be equal with that of a domestic dog. A bears has relatively good hearing; probably equal to a wolf or big cat. But his nose! Here again, the measuring of the sense of smell is not an exact science. But a grizzly's sense of smell is estimated to be roughly seven-times greater than that of a bloodhound. Bears might possibly have the keenest nose in the animal kingdom. 6 - Hibernation - A grizzly can sleep for an uninterrupted six or even seven months during the winter months. Bears are by far the largest living animals capable of doing this. Amazingly, when the grizzly wakes up and walks out of his winter den, he has no ill affects. He loses no muscle-mass and no bone damage.

Bears have to be the best survivors by far of any large mammal. All you have to do is look at the number population in the world, compared to tigers, lions, rhinos, elephants.

My measuring tape is the animals they shared the environment with during the Pleistocene. In N. Africa, the brown bear survived but was exterminated by man. In Pleistocene Europe, the brown bear survived while the cave bear and the cave lion vanished. In Pleistocene N. America, the grizzly survived while the short-faced bears and a comparatively large number of big cat species vanished.

www.pbs.org/newshour/amp/science/why-the-fattest-bear-is-the-picture-of-health Why the fattest bear is the picture of health. Science Nov 21, 2018 05:14 PM EST In her competition photo, Beadnose the bear is hunched down with her chin back, highlighting her thick shoulders (and, it seems, shooting the camera some side-eye). She's one of the stars of Katmai National Park's Fat Bear Week, a social media campaign that began in 2014. Each October, the park asks the public to vote on their favorite "fat bear." This year, Beadnose brought in more than 7,000 votes to earn the title of official Fattest Bear. By this time of year, all of the Alaska park's brown bears are fat out of necessity. They've spent months preparing for the salmon to stop running upstream and the cold to set in, prompting their inevitable retreat into their dens. Over six months of hibernation, the bears will either lose a third of their body weight, almost entirely in fat, or they will perish. A bear without enough muffin top won't make it through the winter. For this reason, Beadnose is considered the pinnacle of bear fitness, weighing more than 600 pounds. According to research done with wild and captive bears, she'll face no long-lasting negative health consequences for her massive weight gain. But for humans in the U.S. and other Western countries, now heading into our holiday season of heavy eating, this kind of drastic weight gain can be damaging. It can bring on Type 2 diabetes, high blood pressure, abnormal cholesterol and increased risk of heart attacks and strokes. How are bears able to jiggle contentedly through the woods every fall and sleep off their extra pounds, while humans are constantly confronted with conflicting diet advice, new medical reports of the dangers of fat and the social stigma that accompanies weight? Scientists say the bears' annual respite makes them into the "metabolic magicians of the mammalian world." As they gorge and then starve, their bodies and hormones keep track of the seasons, making them resilient to drastic changes in their environments. And someday, the secrets of these bears may help inform human health, too. Note: More information on-site.

Brown bears can handle arctic Winter conditions just so long as they can find food.

And just think a bear was able to dig through all this.

BROWN BEAR’S DEN-INSIDE is an interesting find King Kodiak. Between the ability of black bears and grizzlies to hibernate and their wide range of food choices, these bears were able to survive the mass extinction following the last Ice Age. Great survival skills.

Great survival skills. Notice how well round and well made that den was made. Nothing in the middle or in the way. Basically like an architect.

Basically like an architect.Yes, there is a design showing a great deal of thought goes into a bear's den. The first thing I noticed was the rise of the floor before the actual bed area to prevent rain water for reaching the sleeping bear.

Continued: 2) Bears don’t hibernate. Contrary to common belief, bears do not hibernate. Indeed, while bears slow down during the winter, they are not true hibernators like woodchucks. Instead, bears enter what is called torpor. When animals hibernate, they sleep through the entire winter and don’t wake up when they hear loud noises or even if they are moved or touched. In contrast, a bear in torpor can wake up fairly quickly at a noise or a touch.
Interestingly, unlike humans, who would either get bedsores or suffer muscle atrophy from lying in bed all winter, bears in torpor don’t experience significant muscle atrophy. This is most likely due to their ability to absorb their urine and recycle it into a protein that preserves muscle mass.

Continued: 3) Climate change can affect a grizzly bear’s diet. Grizzly bears have become “famous” thanks to pictures of them catching salmon in shallow rivers, such as in the streams of the Kodiak Archipelago of Alaska. However, due to climate change, some bears are switching from eating salmon to eating elderberries, as early warming causes the berries to bloom prematurely. Because bears in the archipelago previously ate up to 75 per cent of a salmon population in a region, researchers believe the dramatic increase in salmon populations will disrupt the entire food chain on the islands. For example, fish carcasses not only enrich the soil around rivers, they also provide an important food source to other animals.

Continued: 4) Grizzly bears love to eat moths. Although grizzly bears eat a variety of different insects, moths are available to them in large numbers. Grizzly bears have been seen moving through boulder fields and turning over heavy rocks to feed on masses of army cutworm moths. A grizzly bear in Yellowstone National Park was seen to have consumed over 40,000 moths in one day. However, eating this many in a day is uncommon.

Bears definitely know how to survive. They do which is what makes them adaptable.

Brown bears know how to adapt well to almost any environment. And the only other predator to make it to polar bear habitat. They have learned how to hunt seals.
