Columbian White-tailed Deer

White-tailed deer are generally distinguished from mule or black-tailed deer by their longer tail that is brown rather than black on the dorsal surface, a smaller metatarsal gland, and in adult males, antlers with prongs arising from a single main beam. The Columbian white-tailed deer (Odocoileus virginianus leucurus) is one of 38 recognized subspecies of O. virginianus.
