White-tailed Deer:

White-tailed deer are highly adaptable and can be found in various habitats across North America. They commonly live in forests, woodlands, and mixed grasslands. White-tailed deer prefer areas with dense vegetation that provides cover and browse for feeding. They are known to thrive in both rural and suburban areas, often adapting to human-altered landscapes. Their range spans from southern Canada throughout the United States, excluding the westernmost states, down to Central America.

Mule Deer:

Mule deer primarily live in the western regions of North America, particularly in the Rocky Mountains, Great Basin, and desert areas. They inhabit various habitats, including mountainous terrain, shrublands, and open woodlands. Mule deer are well adapted to arid environments and can tolerate harsh conditions. They are known to navigate steep slopes and rugged landscapes with agility. Mule deer have a wider range than white-tailed deer, extending from western Canada to the western United States and some parts of Mexico.

Mule Deer vs White Tailed Deer: Diet

Mule Deer vs White Tailed Deer: Similarities And Differences

White-tailed Deer:

White-tailed deer are herbivores with a mixed diet. They are primarily browsers and graze on different plants, including grasses, leaves, twigs, buds, and fruits. During the summer months, they eat a larger portion of herbaceous plants, such as grasses and forbs. In the winter, when food sources become scarce, they rely more on woody browse, like shrubs and tree bark. White-tailed deer are selective feeders, & choose plants based on their nutritional value and palatability. They are also known to exhibit crepuscular feeding behavior, which means they are most active during dawn and dusk.

Mule Deer:

Mule deer eat a diet similar to white-tailed deer but have some differences in their foraging behavior. They are also herbivores and eat various vegetation, including grasses, forbs, shrubs, and browse. Mule deer are more inclined towards browsing, often targeting leaves, buds, and twigs of shrubs and trees. They have a higher tolerance for eating dry, fibrous vegetation and can survive in areas with less nutritious forage. Mule deer are known for their ability to extract moisture from desert plants, which enables them to inhabit arid regions with limited water sources. They are also active feeders during the early morning and late afternoon.

Mule Deer vs White Tailed Deer: Similarities And Differences

White-tailed Deer:

Only the males, or bucks, of the dear species, have antlers, which are shed and regrown annually.

The size and complexity of the antlers vary among dear, with older bucks generally having larger and more impressive antlers. The growth and shedding of antlers are influenced by hormonal changes triggered by the changing seasons.

Mule Deer:

Similar to white-tailed deer, mule deer also have antlers. However, mule deer antlers differ in appearance. They have bifurcated antlers, which means each branch of the antler forks into two tines, resembling the shape of a mule’s ears. Mule deer antlers tend to be larger and more massive than those of white-tailed deer, with multiple points or tines. The number of tines can vary from a few to many, depending on the age and genetics of the individual buck. As with white-tailed deer, only male mule deer grow antlers.
