Across Mongolian Plains / A Naturalist's Account of China's 'Great Northwest'

by Roy Chapman Andrews

The antelope choose a flat plain on which to give birth to their young in order to be well away from the wolves which are their greatest enemy; and the fawns are taught to lie absolutely motionless upon the ground until they know that they have been discovered. Apparently they are all born during the last days of June and in the first week of July. The great herds which we encountered were probably moving northward both to obtain better grazing and to drop their young on the Turin plain. During this period the old bucks go off singly into the rolling ground, and the herds are composed only of does and yearling males. It was always possible to tell at once if an antelope had a fawn upon the plain, for she would run in a wide circle around the spot and refuse to be driven away.

We encountered only two species of antelope between Kalgan and Urga. The one of which I have been writing, and with which we became best acquainted, was the Mongolian gazelle (Gazella gutturosa). The other was the goitered gazelle (Gazella subgutturosa). In the western Gobi, the Prjevalski gazelle (Gazella prjevalski) is more abundant than the other species, but it never reaches the region which we visited.

The goitered antelope is seldom found on the rolling meadowlands between Kalgan and Panj-kiang on the south, or between Turin and Urga on the north, according to our observations; they keep almost entirely to the Gobi Desert between Panj-kiang and Turin, and we often saw them among the "nigger heads" or tussocks in the most arid parts. The Mongolian gazelle, on the other hand, is most abundant in the grasslands both north and south of the Gobi, but nevertheless has a continuous distribution across the plateau between Kalgan and Urga.

On our northward trip in May, when we took motion pictures of the antelope on the Panj-kiang plain, both, species were present, but the goitered gazelle far outnumbered the others—which is unusual in that locality. It could always be distinguished from the Mongolian gazelle because of its smaller size, darker coloring, and the long tail which it carries straight up in the air at right angles to the back; the Mongolian antelope has an exceedingly short tail. The horns of both species differ considerably in shape and can easily be distinguished.

During the winter these antelope develop a coat of very long, soft hair which is light brown-gray in color strongly tinged with rufous on the head and face. Its summer pelage is a beautiful orange-fawn. The winter coat is shed during May, and the animals lose their short summer hair in late August and early September.

Both species have a greatly enlarged larynx from which the goitered gazelle derives its name. What purpose this extraordinary character serves the animal, I am at a loss to know. Certainly it is not to give them an exceptional "voice"; for, when wounded, I have heard them make only a deep-toned roar which was by no means loud. Specimens of the larynx which we preserved in formalin are now being prepared for anatomical study.

Although the two species inhabit the same locality, they keep well by themselves and only once, on the Panj-kiang plain, did we see them running together in the same herd; then it was probably because they were frightened by the car. I doubt if they ever interbreed except in rare instances.

The fact that these animals can develop such an extraordinary speed was a great surprise to me, as undoubtedly it will be to most naturalists. Had we not been able to determine it accurately by means of the speedometers on our cars, I should never have dared state that they could reach fifty-five or sixty miles an hour. It must be remembered that the animals can continue at such a high speed only for a short distance—perhaps half a mile—and will never exert themselves to the utmost unless they are thoroughly frightened. They would run just fast enough to keep well away from the cars or our horses, and it was only when we began to shoot that they showed what they were capable of doing. When the bullets began to scatter about them they would seem to flatten several inches and run at such a terrific speed that their legs appeared only as a blur.

Of course, they have developed their fleetness as a protection from enemies. Their greatest menace is the wolves, but since we demonstrated that these animals cannot travel faster than about thirty miles an hour, the antelope are perfectly safe unless they happen to be caught off their guard. To prevent just this, the gazelles usually keep well out on the open plains and avoid rocks or abrupt hills which would furnish cover for a wolf. Of course, they often go into the rolling ground, but it is usually where the slopes are gradual and where they have sufficient space in which to protect themselves.

The gazelles have a perfectly smooth, even run when going at full speed. I have often seen them bound along when not particularly frightened, but never when they are really trying to get away in the shortest possible time. The front limbs, as in the case of a deer, act largely as supports and the real motive power comes from the hind legs. If an antelope has only a front leg broken no living horse can catch it, but with a shattered hind limb my pony could run it down. I have already related (see [page 49]) how, in a car, we pursued an antelope with both front legs broken below the knee; even then, it reached a speed of fifteen miles an hour. The Mongolian plains are firm and hard with no bushes or other obstructions and, consequently, are especially favorable for rapid travel.
