The Amount of Ground this Grizzly Bear Covers in 15 Seconds is Incredible
Bill Watkins filmed this incredible sequence of a Grizzly Bear in Denali National Park, Alaska, covering some serious ground in a span of 15 seconds. According to Watkins, the bear was spooked by another grizzly on the west side of Highway Pass, causing it to run towards the park road.
Some additional information Bill provided in the original YouTube description can be found below:
Most of the bears that we see along or near the park road are females either with or without cubs or subadults (meaning teenagers 2 1/2 – 5 years old). Females usually kick their cubs out at 2 1/2 years old but I can think of at least two rare occasions where we had a female hold onto her cubs for 4 1/2 years before they were kicked out.
We seldom see adult males along the park road, although if it is late May to early to mid July, a visitor would have a better chance (not a good chance) of seeing a male as that is grizzly bear mating season.
Also, the diet of these bears is primarily vegetation which makes up about 80% of their diet. They literally switch from one plant species to another as the summer season progresses. Pea vine is an important early season food found in the river bars, but grasses, sedges, bear flower, horsetail, blue and soap berries and other plants make up this vegetation diet.
For the most part, Denali bears north of the Alaska Range do not have access to salmon, consequently they are far smaller than their coastal relatives. Average weights for a Denali bear is in the 300-350+ lb range with some males possibly getting up to 500-600 lbs.
The other 20% of their diet consists of anything natural that they can catch or scavenge off of including: ground squirrels (easiest things for them to catch), moose and caribou calves, etc.
Since our bears do not receive any human food or garbage, they do not associate food with people and do not seek them out. Keeping human foods and garbage away from them at all times is the only way to maintain a positive human/bear relationship. The catch is, everyone must be on the same page in securing food and keeping it away from them, in any amounts whether in Denali or elsewhere. Even something as small as a granola bar can begin this food association in a grizzly and things can escalate dangerously from there.
Grizzlies and many other species benefit from wolves as wolves do all the work in bringing down a large animal (successful against adult moose perhaps 5% of the time) and the bears in many cases come in and take it from them. Sometimes if there are enough wolves, they can successfully drive off a bear from a carcass but this type of interaction is rarely witnessed. [source]
