Wild deer are graceful animals found in various habitats, including forests, grasslands, and mountains. They belong to the family Cervidae and are known for their long legs, slender bodies, and antlers, which are typically found on males. Common species include the white-tailed deer and the red deer, each adapted to their specific environments. These animals are herbivores, primarily feeding on leaves, grasses, and fruits. Wild deer are social creatures, often seen in groups called herds. They play a crucial role in their ecosystems by helping to maintain plant diversity and serving as prey for larger predators like wolves and mountain lions.
