Mule deer (Odocoileus hemionus) is a species of deer found throughout the western United States and parts of Canada. Known for their distinctive appearance, mule deer are a popular game animal and are also an important component of the ecosystem. In order to better understand these animals, it is important to know what they eat. In this article, we will explore the dietary habits of mule deer, including what they eat and why they eat it.
What Do Mule Deer Eat?
Mule deer are primarily herbivores, meaning that they feed mainly on plants. Their diet consists primarily of grasses, forbs, and woody plants. Grasses make up the largest portion of their diet, followed by forbs and then woody plants.
In the summer months, mule deer will feed on a variety of grasses, including fescue, bluegrass, and brome. They also feed on forbs such as clover, dandelion, and yarrow. During the winter months, when grasses and forbs are not available, mule deer will turn to woody plants for sustenance. This includes shrubs, trees, and browse plants such as sagebrush, bitterbrush, and manzanita.
How do Mule Deer Graze?
Mule deer are known for their unique grazing habits. They are able to stand on their hind legs to reach taller vegetation, and they also have flexible neck that allows them to reach further than other types of deer. When grazing, mule deer prefer to nibble on vegetation rather than take large bites. They are also known to be selective eaters and will only eat certain types of grasses, depending on their nutritional value.
What Type of Grass does Mule Deer Prefer?
Mule deer prefer to eat fresh, green vegetation, especially in the spring and summer months. They are also known to feed on a variety of grasses, including fescue, bluegrass, and brome. In the winter months, when fresh vegetation is scarce, mule deer will feed on dried grasses and shrubs. However, the type of grass that mule deer prefer to eat will vary depending on the time of year and the availability of vegetation in their area.
Why Do Mule Deer Eat Grass?
Grasses are the primary food source for mule deer because they are easily accessible and provide a high amount of nutrients. Grasses are also high in fiber, which helps to keep the digestive system of mule deer functioning properly. Additionally, grasses are a good source of carbohydrates, which provide the deer with energy to maintain their daily activities.
Forbs are also important in the diet of mule deer because they provide a source of protein and vitamins. Forbs such as clover and yarrow contain high levels of nitrogen, which is necessary for the growth and maintenance of tissues in the deer.
Woody plants, such as shrubs and trees, provide mule deer with a source of food during the winter months when other food sources are scarce. These plants contain high levels of carbohydrates and fiber, which help to keep the deer warm and provide energy during the cold winter months.
Mule Deer Feeding Habits
Mule deer are active feeders, meaning that they feed throughout the day and night. They will often feed in the early morning and late evening when the temperature is cooler. During the heat of the day, mule deer will rest in shady areas to avoid the heat.
Mule deer are social animals and will often feed in groups. This allows them to take advantage of a larger area of food and reduces the risk of predation. When feeding, mule deer use their sensitive noses to locate food and their sharp hooves to dig up roots and bulbs.

Yes, mule deer are active at night and will feed during the night hours, especially during the summer months when vegetation is more abundant.
Conclusion
Mule deer are herbivores and their diet consists primarily of grasses, forbs, and woody plants. Grasses provide a high amount of nutrients and fiber, while forbs provide a source of protein and vitamins. Woody plants provide food during the winter months when other food sources are scarce. Mule deer are active feeders and will feed throughout the day and night, often in groups.
In order to better understand the dietary habits of mule deer, it is important to observe their behavior and understand their habitat. By doing so, we can gain a greater appreciation for these magnificent animals and the role they play in the ecosystem.
