In the old days the prongbuck was found as soon as the westward-moving traveller left the green bottom-lands of the Mississippi, and from thence across to the dry, open valleys of California, and northward to Canada and southward into Mexico. It has everywhere been gradually thinned out, and has vanished altogether from what were formerly the extreme easterly and westerly limits of its range. The rates of extermination of the different kinds of big game have been very unequal in different localities. Each kind of big game has had its own peculiar habitat in which it throve best, and each has also been found more or less plentifully in other regions where the circumstances were less favorable; and in these comparatively unfavorable regions it early tends to disappear before the advance of man. In consequence, where the ranges of the different game animals overlap and are intertwined, one will disappear first in one locality, and another will disappear first where the conditions are different. Thus the whitetail deer had thrust forward along the very narrow river bottoms into the domain of the mule-deer and the prongbuck among the foothills of the Rocky Mountains, and in these places it was exterminated from the narrow strips which it inhabited long before the mule-deer vanished from the high hills, or the prongbuck from the great open plains. But along great portions of the Missouri there are plenty of whitetails yet left in the river bottoms, while the mule-deer that once dwelt in the broken hills behind them, and the prongbuck which lived on the prairie just back of these bluffs, have both disappeared. In the same way the mule-deer and the prongbuck are often found almost intermingled through large regions in which plains, hills, and mountains alternate. If such a region is mainly mountainous, but contains a few valleys and table-lands, the prongbuck is sure to vanish from the latter before the mule-deer vanishes from the broken country. But if the region is one primarily of plains, with here and there rows of rocky hills in which the mule-deer is found, the latter is killed off long before the prongbuck can be hunted out of the great open stretches. The same is true of the pronghorn and the wapiti. The size and value of the wapiti make it an object of eager persecution on the part of hunters. But as it can live in the forest-clad fastnesses of the Rockies, into which settlement does not go, it outlasts over great regions the pronghorn, whose abode is easily penetrated by sheep and cattle men. Under anything like even conditions, however, the prongbuck, of course, outlasts the wapiti. This was the case on the Little Missouri. On that stream the bighorn also outlasted the wapiti. In 1881 wapiti were still much more plentiful than bighorns. Within the next decade they had almost totally disappeared, while the bighorn was still to be found; I shot one and saw others in 1893, at which time I had not authentic information of a single wapiti remaining anywhere on the river in my neighborhood, although it is possible that one or two still lurked in some out-of-the-way recess. In Colorado at one time the bighorn was nearly exterminated, while the wapiti still withstood the havoc made among its huge herds; then followed a period in which the rapidity of destruction of the wapiti increased far beyond that of the bighorn.
I mention these facts partly because they are of interest in themselves, but chiefly because they tend to explain the widely different opinions expressed by competent observers about what superficially seem to be similar facts. It cannot be too often repeated that allowance must be made for the individual variability in the traits and characters of animals of the same species, and especially of the same species under different circumstances and in different localities; and allowance must also be made for the variability of the individual factor in the observers themselves. Many seemingly contradictory observations of the habits of deer, wapiti, and prongbuck will be found in books by the best hunters. Take such questions as the keenness of sight of the deer as compared with the prongbuck, and of the pugnacity of the wapiti, both actual and relative, and a wide difference of opinion will be found in three such standard works as Dodge’s “The Hunting-grounds of the Great West,” Caton’s “Deer and Antelope of America,” and the contributions of Mr. Grinnell to the “Century Book of Sports.” Sometimes the difference will be in mere matters of opinion, as, for instance, in the belief as to the relative worth of the sport furnished by the chase of the different creatures; but sometimes there is a direct conflict of fact. Colonel Dodge, for instance, has put it upon record that the wapiti is an exceedingly gentle animal, less dangerous than a whitetail or blacktail buck in a close encounter, and that the bulls hardly ever fight among themselves. My own experience leads me to traverse in the most emphatic manner every one of these conclusions, and all hunters whom I have met feel exactly as I do; yet no one would question for a moment Colonel Dodge’s general competency as an observer. In the same way Mr. Grinnell has a high opinion of the deer’s keenness of sight. Judge Caton absolutely disagrees with him, and my own experience tends to agree with that of the Judge—at least to the extent of placing the deer’s vision far below that of the prongbuck and even that of the bighorn, and only on a par with that of the wapiti. Yet Mr. Grinnell is an unusually competent observer, whose opinion on any such subject is entitled to unqualified respect.
Difference in habits may be due simply to difference of locality, or to the need of adaptation to new conditions. The prongbuck’s habits about migration offer examples of the former kind of difference. Over portions of its range the prongbuck is not migratory at all. In other parts the migrations are purely local. In yet other regions the migrations are continued for great distances, immense multitudes of the animals going to and fro in the spring and fall along well-beaten tracks. I know of one place in New Mexico where the pronghorn herds are tenants of certain great plains throughout the entire year. I know another region in northwestern Colorado where the very few prongbucks still left, though they shift from valley to valley, yet spend the whole year in the same stretch of rolling, barren country. On the Little Missouri, however, during the eighties and early nineties, there was a very distinct though usually local migration. Before the Black Hills had been settled they were famous wintering places for the antelope, which swarmed from great distances to them when cold weather approached; those which had summered east of the Big Missouri actually swam the river in great herds, on their journey to the Hills. The old hunters around my ranch insisted that formerly the prongbuck had for the most part travelled from the Little Missouri Bad Lands into the Black Hills for the winter.
ON THE LITTLE MISSOURI
When I was ranching on that river, however, this custom no longer obtained, for the Black Hills were too well settled, and the herds of prongbuck that wintered there were steadily diminishing in numbers. At that time, from 1883 to 1896, the seasonal change in habits, and shift of position, of the prongbucks were well marked. As soon as the new grass sprang they appeared in great numbers upon the plains. They were especially fond of the green, tender blades that came up where the country had been burned over. If the region had been devastated by prairie fires in the fall, the next spring it was certain to contain hundreds and thousands of prongbucks. All through the summer they remained out on these great open plains, coming to drink at the little pools in the creek beds, and living where there was no shelter of any kind. As winter approached they began to gather in bands. Some of these bands apparently had regular wintering places to the south of us, in Pretty Buttes and beyond; and close to my ranch, at the crossing of the creek called Beaver, there were certain trails which these antelope regularly travelled, northward in the spring and southward in the fall. But other bands would seek out places in the Bad Lands near by, gathering together on some succession of plateaus which were protected by neighboring hills from the deep drifts of snow. Here they passed the winter, on short commons, it is true (they graze, not browsing like deer), but without danger of perishing in the snowdrifts. On the other hand, if the skin-hunters discovered such a wintering place, they were able to butcher practically the entire band, if they so desired, as the prongbucks were always most reluctant to leave such a chosen ground.
Normally the prongbuck avoids both broken ground and timber. It is a queer animal, with keen senses, but with streaks of utter folly in its character. Time and again I have known bands rush right by me, when I happened to surprise them feeding near timber or hills, and got between them and the open plains. The animals could have escaped without the least difficulty if they had been willing to go into the broken country, or through even a few rods of trees and brush; and yet they preferred to rush madly by me at close range, in order to get out to their favorite haunts. But nowadays there are certain localities where the prongbucks spend a large part of their time in the timber or in rough, hilly country, feeding and bringing up their young in such localities.
Typically, however, the prongbuck is preeminently a beast of the great open plains, eating their harsh, dry pasturage, and trusting to its own keen senses and speed for its safety. All the deer are fond of skulking; the whitetail preeminently so. The prongbuck, on the contrary, never endeavors to elude observation. Its sole aim is to be able to see its enemies, and it cares nothing whatever about its enemies seeing it. Its coloring is very conspicuous, and is rendered still more so by its habit of erecting the white hair on its rump. It has a very erect carriage, and when it thinks itself in danger it always endeavors to get on some crest or low hill from which it can look all about. The big bulging eyes, situated at the base of the horns, scan the horizon far and near like twin telescopes. They pick out an object at such a distance that it would entirely escape the notice of a deer. When suspicious, they have a habit of barking, uttering a sound something like “kau,” and repeating it again and again, as they walk up and down, endeavoring to find out if danger lurks in the unusual object. They are extremely curious, and in the old days it was often possible to lure them toward the hunter by waving a red handkerchief to and fro on a stick, or even by lying on one’s back and kicking the legs. Nowadays, however, there are very few localities indeed in which they are sufficiently unsophisticated to make it worth while trying these time-honored tricks of the long-vanished trappers and hunters.
Along the Little Missouri the fawns, sometimes one and sometimes two in number, were dropped in May or early in June. At that time the antelope were usually found in herds which the mother did not leave until she was about to give birth to the fawn. During the first few days the fawn’s safety is to be found only in its not attracting attention. During this time it normally lies perfectly flat on the ground, with its head outstretched, and makes no effort to escape. While out on the spring round-up I have come across many of these fawns. Once, in company with several cowboys, I was riding behind a bunch of cattle which, as we hurried them, spread out in open order ahead of us. Happening to cast down my eyes I saw an antelope fawn directly ahead of me. The bunch of cattle had passed all around it, but it made not the slightest sign, not even when I halted, got off my pony, and took it up in my arms. It was useless to take it to camp and try to rear it, and so I speedily put it down again. Scanning the neighborhood, I saw the doe hanging about some half a mile off, and when I looked back from the next divide I could see her gradually drawing near to the fawn.
If taken when very young, antelope make cunning and amusing pets, and I have often seen them around the ranches. There was one in the ranch of a Mrs. Blank who had a station on the Deadwood stage line some eighteen years ago. She was a great worker in buckskin, and I got her to make me the buckskin shirt I still use. There was an antelope fawn that lived at the house, wandering wherever it wished; but it would not permit me to touch it. As I sat inside the house it would come in and hop up on a chair, looking at me sharply all the while. No matter how cautiously I approached, I could never put my hand upon it, as at the last moment it would spring off literally as quick as a bird would fly. One of my neighbors on the Little Missouri, Mr. Howard Eaton, had at one time upon his ranch three little antelope whose foster-mother was a sheep, and who were really absurdly tame. I was fond of patting them and of giving them crusts, and the result was that they followed me about so closely that I had to be always on the lookout to see that I did not injure them. They were on excellent terms with the dogs, and were very playful. It was a comic sight to see them skipping and hopping about the old ewe when anything happened to alarm her and she started off at a clumsy waddle. Nothing could surpass the tameness of the antelope that are now under Mr. Hornaday’s care at the Bronx Zoological Garden in New York. The last time that I visited the garden some repairs were being made inside the antelope enclosure, and a dozen workmen had gone in to make them. The antelope regarded the workmen with a friendliness and curiosity untempered by the slightest touch of apprehension. When the men took off their coats the little creatures would nose them over to see if they contained anything edible, and they would come close up and watch the men plying the pick with the utmost interest. Mr. Hornaday took us inside, and they all came up in the most friendly manner. One or two of the bucks would put their heads against our legs and try to push us around, but not roughly. Mr. Hornaday told me that he was having great difficulty, exactly as with the mule-deer, in acclimatizing the antelope, especially as the food was so different from what they were accustomed to in their native haunts.
