The White-Tailed deer (Odocoileus virginianus) is a medium-sized deer native to the United States, Canada, Mexico, Central America, and South America. It is named for its distinctive white tail, which it raises as a signal of alarm. The White-Tailed deer is an important game species in the United States and is also hunted for its meat, known as venison.

One of the most distinctive characteristics of the White-Tailed deer is its antlers, which are shed and regrown annually. Male White-Tailed deer, or bucks, begin growing antlers in the spring and continue to grow them throughout the summer. Antlers are made of bone and are used by male deer for territorial battles and courtship rituals. The shape of a White-Tailed deer's antlers depends on its age, genetics, and nutrition. Generally, younger deer have smaller, simpler antlers, while older deer may have larger, more complex antlers with more points.

The White-Tailed deer has a long and varied history in the United States. Native Americans hunted White-Tailed deer for food and used their hides for clothing and other purposes. In addition to their importance as a source of food, White-Tailed deer also played a significant cultural role for many Native American tribes. In some cultures, the deer was seen as a symbol of strength and nobility, and deer hides and antlers were used in ceremonies and as decorative items. European settlers also hunted White-Tailed deer for food and used their hides for trade. In the early days of the United States, White-Tailed deer were an important resource for both Native Americans and European settlers, who relied on the animals for sustenance and trade.

They are capable of running at speeds of up to 30 miles per hour and can jump over obstacles up to eight feet high. They are also highly adaptable and can thrive in a variety of habitats, including forests, grasslands, and agricultural areas. In addition, White-Tailed deer are known for their keen senses, particularly their sense of smell, which they use to detect predators and locate food.
