Mule deer are native to North America and can be found from Canada down to Mexico. They inhabit various regions across the continent. Mule deer are versatile in their habitat preferences. They live in different environments, including forests, grasslands, deserts, and mountainous areas. Mule deer are medium-sized deer, with bucks (males) being larger than does (females). They can weigh between 100 to 300 pounds and stand around 3 to 4 feet tall at the shoulder. Their large ears resemble those of a mule, which is how they got their name. They have a reddish-brown to grayish-brown coat. Mule deer have keen senses, particularly their excellent sense of hearing and smell. Their large ears help them detect sounds from a distance, while their sensitive noses help them find food and sense predators. They are agile runners and can jump great heights to escape danger.

Mule deer are herbivores, primarily feeding on a variety of plant materials. Their diet includes leaves, twigs, shrubs, grasses, and even fruits. They are adapted to efficiently extract nutrients from tough plant fibers.

Female mule deer give birth to one or two fawns, typically in the spring or early summer. The fawns have white spots on their fur that act as camouflage in the dappled sunlight. Mule deer are most active during the early morning and evening, making them crepuscular animals. They often live in small groups called herds, which can be made up of females, their young, and sometimes a dominant male. They migrate to different elevations in response to changing seasons.

Mule deer populations can be affected by habitat loss due to human activities like urban development. However, their populations are generally stable. Conservation
