The White-Tailed Deer is a medium-sized mammal native to North America. They are easily recognized by their distinctive white underside to their tails, which they raise when alarmed. Adult males, known as bucks, typically have antlers that they shed and regrow annually, while females, called does, do not have antlers. These deer are herbivores, primarily feeding on leaves, fruits, and grasses. They are most active during dawn and dusk, making them crepuscular animals. White-Tailed Deer are social creatures, often found in small groups, and they play a significant role in their ecosystems by helping to maintain plant diversity.
