释义 | fallow deer mammal ![]() ![]() ![]() The rutting buck waves its antlers conspicuously toward the female that it follows in courtship, and it vocalizes loudly with each dip of the antlers. The buck's conspicuous Adam's apple slides up and down the throat with each bark. Rutting bucks form small breeding territories on female ranges and may unite these territories into conspicuous territory clusters called leks. Dominant males tend to use the scent of their urine to attract females during the mating season. The end of the bucks' penis sheath becomes swollen, which straightens a circle of urine-stained hair. Although bucks scrape the soil with their hooves and urinate into these scrapes, as many Old World deer do, they do not roll or rub their bodies in the urine-soaked earth. Females trying to leave a buck's territory may be blocked by the buck, who moves with exaggerated, dancelike steps. If this conspicuous behaviour is ignored by the female, the buck may attack the female and drive her back. The rut peaks in October. A single fawn is born after about 235 days gestation. The females and young live in groups, while the males remain apart except in the breeding season. Mesopotamian fallow deer live along rivers that traverse deserts. Few Mesopotamian fallow deer remain in the wild state, and they are extremely endangered. |
