We can bearly contain our excitement for today’s Species Spotlight Sunday! It’s only fair that we shower our grizzly bear stars with a grand farewell before they dig their dens and settle in for the harrowing winter months.
From late June to September, the famed brown bears build up their fat reserves with an omnivorous diet consisting of plant roots, shoots, berries, mammals, fish, rodents, and, especially, fish. Once they’ve packed on the winter weight, the grizzlies retreat to a den of their own creation to wait out the cold. After their winter prep, these fat bears can weigh up to 900 lbs (410 kg). During their den time, female bears may give birth to young, who usually arrive in pairs!
Other than a mother and her cubs, though, these predators are solitary creatures, who only bother to congregate when salmon is in abundance. To ensure other predators don’t encroach on their land, grizzly bears will mark their territory. You may have seen a grizzly wiggling and shaking up against a tree trunk, and while they may be tending to a hard-to-reach itch, they are also spreading their scent. To maintain their privacy, they may also scratch a tree, rub it, or bite a piece off of the trunk. A grizzly’s ideal environment lies far from development since their preferred home range can span up to 600 square miles (1555 km2). Through their expansive roaming, the grizzly benefits its environment by dispersing seeds, fertilizing the forest floor, and regulating their prey’s populations.
Grizzly bears used to inhabit lands all the way from Alaska to Mexico, but since westward expansion decreased their habitats and introduced hunters, their range was reduced to just 2% of what it once was in the continental United States by the 1920s and 30s. Despite their previous population decline, though, the grizzly bear’s protection under the Endangered Species Act and the introduction of “recovery zones” helped the bear’s population recover and regain stability, with an estimated 1,400-1,700 individuals now in the region.
Now that you’ve taken a paws to learn about the grizzly bear, test your knowledge in our Species Spotlight Sunday story quiz!
