Snow-caked grizzly walks right up to the lens

A dark brown grizzly bear with small rounded ears comes head-on toward the camera through fresh snow, white heaped on its brow, muzzle bridge and back, with a thin conifer and snow-laden branches behind it under a gray sky and a Yukon Wildlife Cams logo at lower left.

The Story

Snow sits on the bridge of the muzzle in a neat white cap, and the animal wearing it is a grizzly bear, walking straight at the lens. More lies heaped across its brow and along its back, fresh from an early-season snowfall in the Yukon.

It pushes out of snow-bowed brush at the right of the frame, a thin conifer behind it against a flat gray sky. The bear keeps coming, head low, legs sunk in the white, until its fur fills the lens.

Under all that snow, the head and feet give it away. The ears are small and rounded, set wide on a broad head, and a grizzly's ears are less prominent than a black bear's. Halfway through, a forepaw lifts and the front claws show long and pale. Grizzly front claws are longer and less curved than a black bear's, suited to digging rather than climbing. The shoulder hump, a large muscle mass above the shoulders, cannot be read head-on under this much snow. Nor can color: grizzlies run from blond to black, often with pale-tipped guard hairs.

Snow has come, and this bear is still on its feet. Far to the south, lower-48 grizzlies typically enter dens between October and December, males later than females. In northern Alaska bears may spend up to 8 months in dens, while on Kodiak some males stay active all winter. None of these is a Yukon figure.

Before any den comes food. In autumn hyperphagia a grizzly may gain more than three pounds a day; this one is broad and heavy, though how much of that is autumn fat the footage cannot say. In the den they do not eat, drink, urinate or defecate, breathing slows to one breath every 45 seconds, and bears may lose 15-30% of body weight. For now, the only weight this bear has not eaten is the snow on its muzzle.

Questions

When do grizzly bears go into their dens?

In the lower 48 they typically enter dens between October and December, with males going in later than females. Den time varies by region, up to 8 months in northern Alaska, while on Kodiak some males stay active all winter.U.S. Fish & Wildlife Service · Alaska Department of Fish and Game

Do grizzly bears really hibernate?

Yes, they den for four to six months in the lower 48 and do not eat or drink in the den. Their body temperature drops only slightly, so they can wake and react to danger.U.S. Fish & Wildlife Service · National Park Service (Yellowstone National Park)

How big is a grizzly bear?

Lower-48 males average 400-600 pounds and females 250-350 pounds. Adults stand about 3.5 feet at the shoulder.U.S. Fish & Wildlife Service · National Park Service (Yellowstone National Park)
