In the Big Horn Mountains, where I also saw a good deal of the mule-deer, their habits were intermediate between those of the species that dwell on the plains and those that dwell in the densely timbered regions of the Rockies farther to the northwest. In the summer time they lived high up on the plateaus of the Big Horn, sometimes feeding in the open glades and sometimes in the pine forests. In the fall they browsed on certain of the bushes almost exclusively. In winter they came down into the low country. South of the Yellowstone Park, where the wapiti swarmed, the mule-deer were not numerous. I believe that by choice they prefer rugged, open country, and they certainly care comparatively little for bad weather, as they will often visit bleak, wind-swept ridges in midwinter, as being places where they can best get food at that season, when the snow lies deep in the sheltered places. Nevertheless, many of the species pass their whole life in thick timber.
THE RANCH-HOUSE
My chief opportunities for observing the mule-deer were in the eighties, when I spent much of my time on my ranch on the Little Missouri. Mule-deer were then very plentiful, and I killed more of them than of all other game put together. At that time in the cattle country no ranchman ever thought of killing beef, and if we had fresh meat at all it was ordinarily venison. In the fall we usually tried to kill enough deer to last out the winter. Until the settlers came in, the Little Missouri country was an ideal range for mule-deer, and they fairly swarmed; while elk were also plentiful, and the restless herds of the buffalo surged at intervals through the land. After 1882 and 1883 the buffalo and elk were killed out, the former completely, and the latter practically, and by that time the skin-hunters, and then the ranchers, turned their attention chiefly to the mule-deer. It lived in open country where there was cover for the stalker, and so it was much easier to kill than either the whitetail, which was found in the dense cover of the river bottoms, or the prongbuck, which was found far back from the river, on the flat prairies where there was no cover at all. I have been informed of other localities in which the antelope has disappeared long before the mule-deer, and I believe that in the Rockies the mule-deer has a far better chance of survival than the antelope has on the plains; but on the Little Missouri the antelope continued plentiful long after the mule-deer had become decidedly scarce. In 1886 I think the antelope were fully as abundant as ever they were, while the mule-deer had woefully diminished. In the early nineties there were still regions within thirty or forty miles of my ranch where the antelope were very plentiful—far more so than the mule-deer were at that time. Now they are both scarce along the Little Missouri, and which will outlast the other I cannot say.
In the old days, as I have already said, it was by no means infrequent to see both the whitetail and the mule-deer close together, and when, under such circumstances, they were alarmed, one got a clear idea of the extraordinary gait which is the mule-deer’s most striking characteristic. It trots well, gallops if hard pressed, and is a good climber, though much inferior to the mountain sheep. But its normal gait consists of a series of stiff-legged bounds, all four feet leaving and striking the ground at the same time. This gait differs more from the gait of bighorn, prongbuck, whitetail, and wapiti than the gaits of these latter animals differ among themselves. The wapiti, for instance, rarely gallops, but when he does, it is a gallop of the ordinary type. The prongbuck runs with a singularly even gait; whereas the whitetail makes great bounds, some much higher than others. But fundamentally in all cases the action is the same, and has no resemblance to the stiff-legged buck jumping which is the ordinary means of progression of the mule-deer. These jumps carry it not only on the level, but up and down hill at a great speed. It is said to be a tiresome gait for the animal, if hunted for any length of time on the level; but of this I cannot speak with full knowledge.
Compared to the wapiti, the mule-deer, like our other small deer, is a very silent animal. For a long time I believed it uttered no sound beyond the snort of alarm and the rare bleat of the doe to her fawn; but one afternoon I heard two bucks grunting or barking at one another in a ravine back of the ranch-house, and crept up and shot them. I was still uncertain whether this was an indication of a regular habit; but a couple of years later, on a moonlight night just after sunset, I heard a big buck travelling down a ravine and continually barking, evidently as a love challenge. I have been informed by some hunters that the bucks at the time of the rut not infrequently thus grunt and bark; but most hunters are ignorant of this habit; and it is certainly not a common practice.
The species is not nearly as gregarious as the wapiti or caribou. During the winter the bucks are generally found singly, or in small parties by themselves, although occasionally one will associate with a party of does and of young deer. When in May or June—for the exact time varies with the locality—the doe brings forth her young, she retires to some lonely thicket. Sometimes one and sometimes two fawns are brought forth. They lie very close for the first few days. I have picked them up and handled them without their making the slightest effort to escape, while the mother hung about a few hundred yards off. On one occasion I by accident surprised a doe in the very act of giving birth to two fawns. One had just been born and the other was born as the doe made her first leap away. She ran off with as much speed and unconcern as if nothing whatever had happened. I passed on immediately, lest she should be so frightened as not to come back to the fawns. It has happened that where I have found the newly born fawns I have invariably found the doe to be entirely alone, but her young of the previous year must sometimes at least be in the neighborhood, for a little later I have frequently seen the doe and her fawn or fawns, and either one or two young of the previous year, together. Often, however, these young deer will be alone, or associated with an older doe which is barren. The bucks at the same time go to secluded places; sometimes singly, while sometimes an old buck will be accompanied by a younger one, or a couple of old bucks will lie together. They move about as little as possible while their horns are growing, and if a hunter comes by, they will lie far closer than at any other time of the year, squatting in the dense thickets as if they were whitetails.
When in the Bad Lands of the Western Dakotas the late September breezes grow cold, then the bucks, their horns already clean of velvet which they have thrashed off on the bushes and saplings, feel their necks begin to swell; and early in October—sometimes not until November—they seek the does. The latter, especially the younger ones, at first flee in frantic haste. As the rut goes on the bucks become ever bolder and more ardent. Not only do they chase the does by night, but also by day. I have sat on the side of a ravine in the Bad Lands at noon and seen a young doe race past me as if followed by a wolf. When she was out of sight a big buck appeared on her trail, following it by scent, also at speed. When he had passed I got up, and the motion frightened a younger buck which was following two or three hundred yards in the rear of the big one. After a while the doe yields, and the buck then accompanies her. If, however, it is early in the season, he may leave her entirely in order to run after another doe. Later in the season he will have a better chance of adding the second doe to his harem, or of robbing another buck of the doe or does which he has accumulated. I have often seen merely one doe and one buck together, and I have often seen a single doe which for several days was accompanied by several bucks, one keeping off the others. But generally the biggest bucks collect each for himself several does, yearlings also being allowed in the band. The exact amount of companionship with the does allowed these young bucks depends somewhat upon the temper of the master buck. In books by imperfectly informed writers we often see allusions to the buck as protecting the doe, or even taking care of the fawn. Charles Dudley Warner, for instance, in describing with great skill and pathos an imaginary deer hunt, after portraying the death of the doe, portrays the young fawn as following the buck when the latter comes back to it in the evening.[[4]] As a matter of fact, while the fawn is so young as to be wholly dependent upon the doe, the buck never comes near either. Moreover, during the period when the buck and the doe are together, the buck’s attitude is merely that of a brutal, greedy, and selfish tyrant. He will unhesitatingly rob the doe of any choice bit of food, and though he will fight to keep her if another buck approaches, the moment that a dangerous foe appears his one thought is for his own preservation. He will not only desert the doe, but if he is an old and cunning buck, he will try his best to sacrifice her by diverting the attention of the pursuer to her and away from him.
[4]. While the situation thus described was an impossible one, the purpose of Mr. Warner’s article was excellent, it being intended as a protest against hunting deer while the fawns are young, and against killing them in the water.
By the end of the rut the old bucks are often exhausted, their sides are thin, their necks swollen; though they are never as gaunt as wapiti bulls at this time. They then rest as much as possible, feeding all the time to put on fat before winter arrives, and rapidly attaining a very high condition.
