Like most other wild animals, bears which have known the neighborhood of man are beasts of the darkness, or at least of the dusk and the gloaming. But they are by no means such true night-lovers as the big cats and the wolves. In regions where they know little of hunters they roam about freely in the daylight, and in cool weather are even apt to take their noontide slumbers basking in the sun. Where they are much hunted they finally almost reverse their natural habits and sleep throughout the hours of light, only venturing abroad after nightfall and before sunrise; but even yet this is not the habit of those bears which exist in the wilder localities where they are still plentiful. In these places they sleep, or at least rest, during the hours of greatest heat, and again in the middle part of the night, unless there is a full moon. They start on their rambles for food about mid-afternoon, and end their morning roaming soon after the sun is above the horizon. If the moon is full, however, they may feed all night long, and then wander but little in the daytime. Aside from man, the full-grown grisly has hardly any foe to fear. Nevertheless, in the early spring, when weakened by the hunger that succeeds the winter sleep, it behooves even the grisly, if he dwells in the mountain fastnesses of the far northwest, to beware of a famished troop of great timber wolves. These northern Rocky Mountain wolves are most formidable beasts, and when many of them band together in times of famine they do not hesitate to pounce on the black bear and cougar; and even a full-grown grisly is not safe from their attacks, unless he can back up against some rock which will prevent them from assailing him from behind. A small ranchman whom I knew well, who lived near Flathead Lake, once in April found where a troop of these wolves had killed a good-sized yearling grisly. Either cougar or wolf will make a prey of a grisly which is but a few months old; while any fox, lynx, wolverine, or fisher will seize the very young cubs. The old story about wolves fearing to feast on game killed by a grisly is all nonsense. Wolves are canny beasts, and they will not approach a carcass if they think a bear is hidden near by and likely to rush out at them; but under ordinary circumstances they will feast not only on the carcasses of the grisly's victims, but on the carcass of the grisly himself after he has been slain and left by the hunter. Of course wolves would only attack a grisly if in the most desperate straits for food, as even a victory over such an antagonist must be purchased with heavy loss of life; and a hungry grisly would devour either a wolf or a cougar, or any one of the smaller carnivora off-hand if it happened to corner it where it could not get away.
