Big Grizzly Bear Feeding on Moose Bull Carcass

This would be Considered one of the largest Grizzly Bear Boars in this area, feeding on also one of the Largest Moose Bulls in this area. There was no sign of struggle on the far side of this lake, so it is not suspected that a Bear killed this Moose Bull. This big Grizzly is Certainly making sure no Calorie goes to waste. An entire Day of eating berries(this time of year) for this Grizzly May be equaled in just a few mouthfuls of this Calorie Dense Carcass, which ends up feeding many.
In just a few more Days, there may be no sign of this Moose Bull Carcass, as Nature absorbs all.. even Fur disappears and becomes insulation for Birds tree nests, etc.
Thank you for your patience with this video, it was cropped in from about 1km away.

Grizzly Bear Grabs and Runs from a Moose Bull Carcass

This Grizzly Bear came in, grabbed what He could, and hastily ran back into Forest cover.. spending only about 3 minutes out in the open. We heard another Bear.. a Black Bear, was seen on this Moose carcass earlier on this day. There was apparently no signs of struggle on the far side of the Lake shore, and the Moose Bull was very large for this area of the Canadian Rockies.. so, likely not killed by these Bears. *We are cropping quite a bit from a long distance and Thank You for your patience with Us there.

Berry Season is a Time For Extra Care in Bear Country

It is Berry Season now and that means a time to be Extra Careful when out in Favorite Shared Spaces. Bears can become very focused on eating Berries and when in dense bush, Surprise Encounters are Far More Common. If a Bear knows you are there, or approaching on a trail, the chances of a difficult situation is less likely. Be Safe out there!

Wonderful Grizzly Family Makes Another Appearance

Grateful to see this amazing Grizzly Family for a short appearance before they head up in altitude towards new green growth. We may see them again during berry season, but just knowing they are doing well is wonderful. As newborns, these cubs had something about them that was particularly amazing as you can see.

Biggest Grizzly Seen in the Area So Far

The Biggest Grizzly Seen in the Area So Far is such a magnificent sight. We thought a little tribute to this amazing Apex creature was in order, so here is a good look at this incredible fella. We are not sure, but He may have recently been seen mating with one of the biggest Sows in the area. If so, their offspring will be exceptionally gifted in the size department.

First Sighting of Mature Grizzly Mum with New Offspring

It Appears the 3 Amigo's Mum is now raising/protecting 2 newborns(coy). Back in 2019, she had 3 that looked exactly like these 2(little "Spirit" faces), but She was quite a bit Heavier at the same time of year back then. The cooler Spring sure has seemed to delay their ability to put on weight. Hopefully, we get lots of moisture in the immediate and this Family finds a safe space far away from the Highways.

An Amazing Grizzly Family Today and as Newborns

Here is our first sighting of this Amazing Grizzly Family Today and as Newborns. They looked like they weathered hibernation very well! The Family were seen on Mountain Peaks in late Spring and now with some slight adjustments to their territory, down in the Valley Bottom. Many call this Famous Mother "Grizzma" as she is very well known, such a Beautiful Mother Bear, and has an amazing temperament. Along with some footage of Grizzma and Her Cubs today, we have included our First Sighting of them back in 2020, as newborns. We Hope Cubs and Mum stay together for the remainder of this year for their safety, but we can see that it may be difficult for all of them to occupy the same Den when that time comes.

3 Year Old Grizzly Male Hanging in There

Young Boars in the Grizzly Bear World face a lot of obstacles. This young Male has been constantly on the Move in his space/territory as he successfully manages to avoid larger Grizzlies and feed himself in a popular area. He was one of the "3 Amigos" from 2019. His siblings are also in this area, but they seem to be preferring distance from Him now at this age. His Mother was very Gifted with size and experience that She seemed to have passed on to this young fella.

Grizzly Bear Siblings Doing Well on Their Own

These 2 Grizzly Bear Siblings were of a group of 3, but just these two stayed together while the third one ventured out on his own. So far, these two have been doing well bouncing on and through territorial edges of many larger Bears. Here you can also see that you have to be bear aware everywhere as common hiking hubs contain many trail junctions often also used by Grizzly and Black Bears. We hope to see these two beautiful Bears continue to do well in this amazing space.

Are They Siblings, a Mating Pair, or Mother and Teenager?

This is one of the most interesting pair of Grizzly Bears right now as no one seems to know. We have heard that they are Twins, a Mating Pair, but what we witnessed today.. possibly a Mum with a Teenage Cub. Regardless.. they are wonderful to Witness.

Happy Grizzly Siblings or a Mating Pair?

These two Grizzly Bears have travelled quite a distance over the last week. Originally, they were thought to be Siblings, but were seen Mating, so it is possible that they are an early Mating Pair. They could also simply be Siblings that are acting out natural instincts present during this time of year. It is early Bear Mating Season.

Grizzly Cubs Going for a Swim in Athabasca River

These Grizzly Cubs are looking good after hibernation. Here they go for a Swim in Athabasca River, moving around quite a bit early in the season. Athabasca River is not yet high or too powerful as we have not had very many hot days, forcing fast Spring Mountain runoff. The Grizzly Cubs were newborns in 2019, now 3 years old and with one less sibling than last summer. The Grizzly Siblings could have parted ways due to Male/Female differences being more evident, which is common as they become this age.

Big Beautiful Grizzly Sow First Sighting this Year!

Our First Sighting of this Big Girl out of Hibernation was a nice surprise. She was in Great condition.. looking really Big and Strong as She begins her travels. Her Paws and Nose were never still for long as she searches for scents of substance. The beginning shows a clip of her Hunting Ground Squirrels along with when she had a newborn Cub Last Year, to compare. Her Gifted structure looks even bigger and fuller this year. We were hoping to see Her trying Motherhood again this year, but no luck on that account. Regardless, it was an incredible encounter that took place in a perfect setting with lots of safe space to observe. She is a Great Teacher that the Rockies are Lucky to Have! *We had a little fun on the beginning of this.. hope it brings a smile your way.

Grizzly and Her Newborns - First Sighting

Our First encounter with a special Grizzly Mother and her newborn cubs this year. She is such a patient and well tempered Grizzly sow and we are now lucky enough to witness her with her second set of Cubs over the last several years. It was an exciting day as we were not certain she was okay over the Winter, but clearly she was. Grizzly Bears produce only two or three cubs every three years and their survival rate is unfortunately very low. Everyone in this location of Canada's Rockies will be Cheering this family on!

This grizzly bear cub is not only very well fed, but seems to be very laid back here today.

She's Got Moves! ..Big Grizzly Bear Sow Displaying some Agility on the Hunt. Earlier, this Grizzly Bear caught an Elk calf and now she is hunting ground squirrels. This Big Grizzly was the Mum of One very Healthy Cub a couple weeks ago, but lost it likely to another big Boar. She has travelled up to 60km in the last few days. They do have such a tough life, but here her calories in were more than calories out. We sure hope to see this awesome Grizzly Bear produce offspring again soon.

Big Grizzly Cubs as Newborns and Leaving Mum Today

A Rare occurrence.. Grizzly Bear Cubs from Newborns(sorry for the shake) to Sub-Adults. It's very rare for Grizzly Bear Cubs to make it this far, and especially 3 Siblings together. They just left their Mother a short time ago and are finding their space together. Here the Grown Cubs become separated, but never venture far as we witness them reunite late the next evening. Their exceptional noses prove to be their most powerful tool in keeping together. As a Unit, these Grizzly Bear Cubs stand a much better chance of survival.

Grizzly Bear - Brown Bear Species

Genetic science reveals the grizzly to be a subspecies of the brown bear (Ursus arctos). In North America, "brown bear" is also known as "grizzly bear", being all the same species, Ursus arctos.

Coastal grizzly bears are larger and darker than inland grizzlies. They were considered a different species from grizzlies at one time. Kodiak grizzly bears also were considered a distinct species. At that time there were five different species of brown bear, including these three in North America.



Grizzly Bear Size

Female grizzlies usually weigh 130–180 kg (290–400 lb), while adult male grizzly bears weigh on average 180–360 kg (400–790 lb). Female Grizzly Bear average weights would be 136 kg (300 lb) inland and 227 kg (500 lb) coastal. One study found that the average weight for an inland male grizzly bear was around 272 kilograms (600 pounds), and the average weight for a coastal male was around 408 kg (899 lb). Newborn grizzly bear cubs uausally weigh less than 500 grams (1.1 lb).



Grizzly Bear Fur Color

Although grizzlies color can be blond to nearly black, grizzly bear fur is usually brown with darker legs and commonly white or blond tipped fur on the flank and back.



Grizzly Bear Physical Characteristics

A large muscular hump exists on adult grizzly bear shoulders. Aside from the distinguishing hump, grizzly bears also have "dished in" face profiles with short, rounded ears.

Grizzly bear's rear end is lower than its shoulders, where as a black bear's rump is higher than its shoulders.

Grizzly bear's front claws are usually 2–4 inches in length, where as a black bear's claws measure about 1–2 inches in length.



Grizzly Bear Hibernation

Grizzly bears hibernate from 5 to 7 months each year unless they live in warm climates where they may not hibernate at all. During hibernation, female grizzly bears give birth and their offspring will consume milk from their mother for the remainder of the hibernation period.

Grizzly bears must consume an immense amount of food to prepare for hibernation. Bears can gain hundreds of pounds during the period just before hibernation called hyperphagia. In this period, grizzlies may consume up to 10 times the amount of calories compared to Spring and Summer.

Bears do not eat during hibernation. Grizzly bears do not defecate or urinate throughout the entire hibernation period. Male grizzly bears usually come out of hibernation in early to mid-March, while females emerge in April or early May.

Bears often wait for a snowstorm as a trigger to enter their den. This behavior reduces the chances that predators will find the den. Grizzly Bear dens are typically at elevations above 1,800 m (5,900 ft) on north-facing slopes.

Inland or Rocky Mountain grizzlies spend nearly half of their life in dens while coastal grizzly bears spend less time in dens. If food is very plentiful year round, grizzly bears may not hibernate at all.



Grizzly Bear Reproduction

Grizzly bears have one of the lowest reproductive rates of all land mammals in North America. Grizzly bears do not reach sexual maturity until they are at least five years old. After mating, females delay embryo implantation until hibernation, during which miscarriage can occur if the female is not in good enough condition. Female grizzly bears usually produce two cubs in a litter, with the mother caring for the cubs for up to two years before mating again.

Grizzlies are normally solitary animals, but in coastal areas, grizzlies gather around streams, lakes, rivers, and ponds during the salmon spawn. Females (sows) produce one to four cubs that are small and weigh only about 450 grams (1 lb) at birth. Unfortunately, most grizzly bear cubs do not make it through their first year due to many factors.



Grizzly Bear Lifespan

The average lifespan for a grizzly boar is estimated at 22 years, with sows living slightly longer at 26.

Females live longer than males due to their less dangerous life, as they do not fight during mating season like boars do. The oldest known wild inland grizzly was about 34 years old(Alaska), with the oldest known coastal bear being 39. Captive grizzlies have been known to live as long as 44 years.
