In my continued revamp of the blog, today’s post will be part of a monthly series highlighting wildlife and nature. I hope you find it fun and informative. I’ll be sharing images from some amazing nature photographers. My words are here only to compliment their photos!
This month we’re going to the bears. Why bears? Bears have such a varied life–much more than I would have anticipated. They are part of a delicate ecosystem that needs them. They are considered “keystone” predators—meaning their survival in their natural habitat is critical for the entire biological community, including humans. Here is a peek into the secret lives of bears.
The photos below are shared with the permission of Scott Randall. I think you’ll agree his images present a captivating look at these amazing bears. He took these photos while on trips to Alaska.
1.Brown, black, and grizzly. (This sounds like a great name for a band!) No matter what we call the bears, they can come in a variety of colors. So, a black bear can be brown in color (or cinnamon, blond, even white).
- Brown and grizzly. All grizzly bears are brown bears, but not all brown bears are grizzly bears. Grizzly is a subspecies of brown bears.
- Brown and black. One quick way to distinguish between a brown bear and black bear is in profile. Brown bears have a camel-like hump between their shoulder blades while black bears do not.
- Brown bears are the most common, but 95 percent of the population lives in Alaska. If you’re in the lower 48 and you encounter a bear, you’re probably eye-to-claw with a black bear.
2. Sleep, perchance to dream. Bears can lose about 40 percent of their body weight while hibernating, which is why they have to bulk up in the summer. A bear can consume 90 pounds (40 kg) of food per day to prepare for the long sleep.
- While hibernating, a bear’s heart rate slows to eight beats per minute.
- Anyone who has seen a bear eating Snickers bars from a campsite knows that they are omnivores. Depending on their habitat, they will eat grasses, berries, nuts, fruits, honey, and fish. In the Pacific Northwest and Alaska, salmon is a favorite. One of my bucket list trips: bear watching at Katmai National Park. The short clip below (narrated by David Attenborough) shows grizzly (brown) bears fishing for salmon at Brooks Falls, Katmai. I feel bad for the salmon, but the bears are impressive.
3. Home on the range. Bears cover a lot of ground. Males stake out a territory of 200-500 square miles (500-1,300 square km) while females maintain a slightly smaller area.
- One way they mark their turf is by rubbing their scent along trees, but areas overlap and they tend not to enforce boundaries. Otherwise, bears are mostly solitary, coming together to mate or fish when salmon are running.
An extra-special thank you to Scott Randall for allowing me to share his photos! Please visit his photo blog for more amazing shots like these.
