Odocoileus virginianus
White-tailed deer are generalists and can adapt to a wide variety of habitats. The largest deer occur in the temperate regions of North America. The northern white-tailed deer ("O. v. borealis"), Dakota white-tailed deer ("O. v. dacotensis"), and northwest white-tailed deer ("O. v. ochrourus") are some of the largest animals, with large antlers. The smallest deer occur in the Florida Keys and in partially wooded lowlands in the neotropics.
