A group of European scientists have determined that a male reindeer’s air sac, influencing vocal sound and neck contour, may contribute to his sexual prowess and reproductive success. The results of this research have recently been published in Journal of Anatomy.
As in other species with harem-like mating systems, the voice organs of reindeer differ according to gender. Adult males have a much larger air sac than females and the young.
