Deer are herbivores, meaning their diet consists entirely of plant matter. Their food choices are based on availability, nutritional value, and season.
The Core Diet Includes:
- Grasses – Soft, tender blades, especially in spring and summer.
- Leaves – From shrubs, bushes, and low tree branches.
- Fruits – Apples, berries, persimmons, and plums when available.
- Acorns and Nuts – A vital high-energy food source in fall.
- Twigs and Bark – In winter, when other food is scarce.
- Farm Crops – Deer often venture into farmlands for corn, soybeans, and alfalfa.
Seasonal Breakdown: What Deer Eat Throughout the Year
Spring
- Tender grass shoots
- Wildflowers
- Budding leaves
- Clover and other herbs
Why it matters: After a long winter, deer focus on nutrient-rich greens to rebuild strength and recover energy.
Summer
- Green leaves and stems
- Fruits like berries
- Crops such as corn or soybeans (in rural areas)
Why it matters: Deer need water-rich foods during the heat and plenty of energy for growth and antler development.
Fall
- Acorns and other nuts (called “mast”)
- Apples, persimmons, pumpkins
- High-protein crops like soybeans
Why it matters: This is the deer’s “fattening-up” season. They bulk up before the lean winter months.
Winter
- Twigs, bark, and buds from trees
- Evergreen plants
- Dried grasses under snow
Why it matters: Food is scarce, so deer survive on whatever fibrous plant material they can find.

FAQs
What is a deer’s favorite food?
Acorns and apples are among the most loved, especially in fall. In farmland areas, deer are also drawn to corn and soybeans.
Do deer eat meat?
No. Deer are strict herbivores and do not eat meat, though they may occasionally chew bones for minerals.
Can deer eat bread or human food?
They can, but it’s not healthy. Processed human foods can disrupt their digestion and should be avoided.
What do deer eat in the forest?
Mostly browse—twigs, leaves, bark, and forest floor plants like ferns or mushrooms.
Final Thoughts: Nature’s Adaptive Grazers
Deer are remarkably adaptable eaters. Whether it’s tender spring greens or woody twigs in winter, they know how to survive and thrive with what nature provides. Understanding their seasonal diet can help you better appreciate these creatures whether you’re watching from afar or tracking them in the wild.
