A mother and two cubs
As the cubs grow larger and stronger the mother wanders farther afield with them, and, from sacrificing all her time and desires to their needs and safety, comes gradually first to tolerate, and toward the end of the season rather to resent, their persistent demands upon her. One imagines that it is with a final indifference and relief that she sends them off to shift for themselves. For, like other animals, a bear, while showing the most devoted and courageous love for her children while they are helpless, has a very short-lived affection for them once they cease to need her protection. In one instance the Lodges tried the experiment of returning some half-grown cubs to their mother after a comparatively short separation, during which she and her mate had been together in the main pit. The two cubs had only been by themselves for a few weeks, and before they were finally returned to the pen with their mother they were kept for some days separated from her by nothing more than an iron grating. Yet as soon as they were put into the pit with her she seized one of them and killed it, and was starting up her exercise tree after the other which had taken refuge there when the owners interfered and rescued the youngster. Here, as I see it, was a case of artificial separation which, once the mother had accepted, placed her, as far as her own feelings went, in exactly the same frame of mind toward her cubs as though she had abandoned them in the natural course of things and their company had afterward been forced upon her.
Neither the Black Bear nor the grizzly is really a sociable animal, but free Black Bears occasionally play together, which grizzlies never seem to do. Under ordinary circumstances, however, Black Bears have a funny trick of pretending not to see each other when they meet. If one of them comes into a marshy meadow or a small open glade in the woods where one or two others are already feeding, he will make the most laughable pretence of not seeing them. He will stop at the edge of the opening and go through all the motions of examining the country, carefully looking, however, everywhere but in the direction of the other bears; all of which is vastly amusing to one familiar with the keenness of his senses and the alertness of his attention, and the practical impossibility of getting within seeing or hearing distance of him without his knowing it. Meanwhile the bears already on the ground play their part in the little comedy with all the good will in the world. They have undoubtedly been aware of the approach of the newcomer long before any human watcher of the scene could have suspected it. But they give no outward sign of being aware of the new arrival. If, however, the intruder had happened to have been a grizzly they would undoubtedly have taken to their heels or taken refuge in the nearest tree with loud puffings and snortings some minutes before he reached the scene. Yet these same bears, once they have fed their fill, will frequently go to playing together as one never sees the grizzlies do. Two of them will stand up and wrestle, roll each other over and over, chase each other about, and generally have a fine romp. As a rule, however, this sort of play takes place between bears of different sizes, and the smaller one sometimes gets well thrown about and mauled.
One of the most entertaining experiences that I ever had in the woods was connected with just such an after-dinner romp between two Black Bears. I was photographing grizzlies in the Rocky Mountains in Wyoming, and had set up my camera and flash-light apparatus near a likely looking trail. My flash-pan was placed on top of a ten-foot pole stuck in the ground under a small pine tree, and a fine wire was run from the switch that operated the apparatus across the trail and tied to a convenient bush. I had completed my arrangements about half-past four in the afternoon and had concealed myself in a mass of fallen timber some seventy-five or eighty feet away prepared to wait for dusk.
Soon after I got settled I noticed two Black Bears in a little clearing to my left and, for something to do, I set to watching them. For some time they fed quietly here and there and then they took to playing. One of them was quite a bit larger than the other, but the smaller one was game and though he got considerably the worst of the rough sport they kept the play up for quite a while. Suddenly, however, in the very midst of an excited wrestling match, the little fellow drew away, stood up on his hind legs and listened for a moment, and then went up a convenient tree, his companion following his example and taking refuge in another one. I was much interested over this turn of affairs and kept a close watch to see what was going to happen next. But, after quite a little wait, the bears seemed to make up their minds that it had been a false alarm and, coming down from their respective trees, they resumed their rough and tumble fun. Not for long, however. It was only a minute or two before they repeated their former maneuvers, and this time they appeared to have no doubt as to the imminence of danger. They had worked their way over to my side of the clearing, and when they broke for shelter the little bear took refuge in the small pine tree under which my flash-pan stood, his companion selecting a larger tree a little further away. And sure enough, almost as soon as they were well off the ground an old grizzly came stalking dignifiedly out of the woods and down the trail upon which my camera was set. But he had evidently noticed that something questionable was going on, and he walked over toward the tree where the larger bear was sitting. The latter, conscious of his advantage of position, greeted the grizzly’s approach with a volley of puffs and snorts, and after looking around him in a disdainful sort of way, the grizzly sauntered over toward the smaller bear’s tree, where the same performance was gone through. Here, however, the grizzly found something that aroused his curiosity more keenly than a mere Black Bear, for he discovered my pole and flash-pan. He stood up on his hind legs and easily sniffed the top of the pan and then, discovering the wire, he followed it without touching it away from the pine tree and across the trail to where it was fastened. Then, his curiosity getting the better of him, he raised one front paw and pulled the bush toward him, whereupon the charge of powder exploded with a huge puff of smoke, and as I stood up in my retreat to get a better view of the outcome I caught a glimpse with one eye of a big grizzly turning a double back somersault, while with the other I saw a small Black Bear take one desperate leap from the branches of his pine tree and disappear into the wood in huge leaps.
When the last act of this little comedy began I had risen to my feet in order to get a clear view of what took place, and when the smaller Black Bear had disappeared into the woods I saw that his larger companion had become aware of my presence. I once more concealed myself among the branches, but the Black Bear in the tree kept an eye in my direction and when, at the end of five minutes or so, the smaller bear returned cautiously to the scene of his recent discomfiture and began to coax his friend to come down and resume their play, it was amusing to watch the cross-purposes at which they found themselves. For the one up the tree who knew of my presence was afraid to come down and yet unable to explain the circumstances to the one on the ground, and he in his turn was utterly unable to make head or tail of the other’s actions. He finally gave up the attempt to persuade him and wandered away into the woods, and at the end of half an hour or so the other bear, evidently with serious misgivings, came carefully down the opposite side of his tree and made off at the double quick.
The Black Bear’s habits of hibernation are less rigid and apparently less developed than the grizzly’s. To begin with, they are far less industrious in providing themselves with a den, and less particular in having it weatherproof and well concealed. The grizzly habitually seeks out some natural cave or shelter in the rocks, high up in the mountains, often above snow line. This he prepares for occupancy by raking into it whatever he can find in the way of leaves or dried grasses, and sometimes stops up with earth and stones such holes or openings as would expose the interior to the weather. The Black Bear is far less particular. Any old place that offers him some fair promise of protection and privacy seems good enough for him. He dens up at much lower altitudes, goes into winter quarters later and comes out much earlier. One of his favorite devices is to dig a hole under the butt end of a fallen tree, rake a few leaves into the opening, and then crawl in himself. Sometimes, when the tree is a good-sized one and the roots hold the butt of it a little clear of the ground, he is saved the trouble of digging at all and makes a sort of nest in the space beneath the trunk. At other times he will dig a hole in the soft ground, and, of course, occasionally uses caves or other natural retreats if he happens to find them handy. Ben, it will be recalled, dug under the floor of my barn when it came to be his bedtime.
The time for denning up varies with the locality and the weather, and throughout the North-west is anywhere from November 1 to January 1. Unlike the grizzly, however, the Black Bear will often come out for a while if a warm spell follows his denning up. The Lodges note that their bears, once they are settled in their winter caves, never seem to pay any further attention to the weather. But while this is probably the rule, I have seen Black Bears out in some numbers late in December after there had been severe freezing weather during which all bears had denned up.
There is some difference of opinion as to their habits further south, and some authorities claim that at the extreme southern limit of their range the bears belonging to the Black Bear group do not hibernate at all. I incline, however, from what I have seen—or rather failed to see—to the opposite belief; for in parts of Old Mexico where, in the spring, I have seen many bears, I have again in the winter time failed to see either them or their fresh tracks, and upon making inquiry of the Indians have been told that they were asleep.
Moreover, Mr. Charles Sheldon, of New York, who for fifteen years has made a close study of bears in their natural state and has spent four years in Mexico studying bear and sheep, informs me that all the bears den up almost as early in those mountains as they do further north, and that he has never seen bears in Mexico come out of winter quarters earlier than in the United States.
