“The Orongo is found in small herds from five to twenty or forty head, rarely collecting in large troops of several hundred, and this only where the pasturage is good and plentiful. Though a few of the old bucks, usually accompanying every herd, are more cautious and experienced, the Orongos generally are not so wary in their habits. In their flight the males follow the herd as though to prevent straggling; whilst with the Dzerens and Kara-sultas this order is reversed. When in motion, either leisurely or at full speed, the Orongo holds its horns erect, which adds greatly to its appearance. When trotting--its usual pace--the legs move so quickly that at a distance they are invisible, and dogs or wolves are soon left behind. We arrived in Tibet during the breeding-season of these animals, which begins late in November and lasts a month. “At this time the full-grown males are in a most exited state, taking little food and soon losing the fat which they had gained during summer. The buck soon forms his harem of ten to twenty wives, and these he jealously guards lest any of them should fall into the power of a rival. No sooner does he see an adversary approaching than he, the lawful lord of the herd, rushes to the encounter with head lowered, uttering short deep bleats. The combat is fierce, and the long sharp horns inflict terrible wounds, often causing the death of both antagonists. Should one feel his strength ebbing, he takes to flight pursued by his enemy, then suddenly wheeling round receives the latter on his horns. As a proof of the fury with which they fight, I remember shooting one of the combatants, who, to my surprise, continued the fight for several minutes after he had received his death-wound, and then suddenly expired. If a doe chance to stray from the herd, the buck immediately gives chase, and, bleating as he goes, tries to drive her back again. While his attention is thus engaged the others give him the slip, and pursuing first one, then another, he often loses his whole harem. At last, deserted by all, he gives vent to his fury and disgust by striking the ground with his hoofs, curving his tail, lowering his horns, and bleating defiance at his compeers. From morning until evening these scenes are constantly occurring, and there appears to be no bond of union between the male antelope and his does; to-day they consort with one buck, to-morrow with another.
