When first born, the calves are reddish yellow in color, do not possess any noticeable hump, and look very much like ordinary domestic calves, except that possibly the tail is slightly shorter. Before very long, however, they commence to grow darker in color, and I have seen calves in August that at a little distance seemed almost as dark as the adult buffalo.
The cow is devoted to her calf, and is ready to fight for it against any enemy except man. Usually, in the buffalo chase, the cow, thoroughly frightened, paid no attention to the calf. But, on the other hand, cases have occurred, where men have been capturing calves to rear in captivity, in which the cow refused to desert her offspring, but turned upon the captor of the calf and charged him with the utmost boldness.
Colonel Dodge instances a case where a number of bulls devoted themselves to protecting a calf against wolves. He says, “I have seen evidence of this many times, but the most remarkable instance I ever heard of was related to me by an army surgeon who was an eye-witness. He was one evening returning to camp after a day’s hunt, when his attention was attracted by the curious actions of a little knot of six or eight buffalo. Approaching sufficiently near to see clearly, he discovered that this little knot were all bulls, standing in a close circle with their heads downward, while in a concentric circle, at some twelve or fifteen paces distant, sat, licking their chops in impatient expectancy, at least a dozen large gray wolves--except man, the most dangerous enemy of the buffalo. The doctor determined to watch the performance. After a few moments the knot broke up, still keeping in a compact mass, and started on a trot for the main herd some half mile off. To his very great astonishment, the doctor now saw that the central and controlling figure of this mass was a poor little calf, so newly born as scarcely to be able to walk. After going fifty or one hundred yards, the calf lay down; the bulls disposed themselves in a circle as before, and the wolves, who had trotted along on each flank of their retreating supper, sat down and licked their chops again. This was repeated again and again, and although the doctor did not see the finale (it being late and the camp distant), he had no doubt that the noble fathers did their whole duty by their offspring, and carried it safely to the herd.”
