what do deer eat
Deer are herbivores with a varied diet that shifts by season, location, and food availability. Their favorites include acorns, browse like twigs and leaves, forbs, crops, and mast like fruits and nuts.
Core Diet Basics
Deer primarily consume plants, with over 400 species identified in some studies alone. Browse (woody leaves and twigs) and forbs (broad-leafed herbs) make up over 80% of their intake year-round, providing essential nutrition. Mast such as acorns dominates in fall, spiking to 28% of their diet, while grasses and lichens fill gaps.
Top 20 Favorite Foods
Field & Stream ranks these as prime attractants for whitetails and mule deer, based on preference and seasonal pull:
| Food | Key Notes |
|---|---|
| Acorns | #1 choice; up to 80% of diet in season, especially capless ones. |
| Alfalfa | Eaten year-round; deer dig through snow for it. |
| Apples/Pears/Persimmons | Top fruits; bonus berries, sumac, honey locust pods. |
| Clover/Brassicas/Cowpeas | High-protein legumes and crops. |
| Corn/Soybeans/Cereal Grains/Milo | Agricultural favorites whenever available. |
| Fall Leaves | Prefer fresh red ones (maple, dogwood) for sugar. |
| Forbs/Saplings/Shrubs | Staples like aspen, willow, sagebrush. |
| Beechnuts/Northern White Cedar/Fir Needles | Winter browses; mountain laurel in tough areas. |
| Treetops | Felled or fallen; key in logged zones. |
Seasonal Shifts
- Spring/Summer : Tender shoots, forbs, soft mast (berries), and new alfalfa growth fuel lactation and antler development.
- Fall : Acorns and hard mast take over for fat storage; crops like corn get hammered.
- Winter : Twigs, buds, evergreens, and leftover crops; they'll eat bark if desperate.
Imagine a whitetail doe in autumn: She ignores nearby grass to bulldoze leaves for acorns, her fawns trailing, as this nutty feast powers them through lean months ahead.
Regional Variations
Whitetails in the Southeast crave dewberry vines and brassicas, while Western mule deer hit bitterbrush and sagebrush hard. UK roe deer mix grasses, sedges, and bark. Crops boost everywhere—deer hit fields opportunistically for nutrition.
Forum & Trending Buzz
Online chatter (as of early 2026) spikes on backyard feeding: "Acorns rule, but avoid corn in winter—it clumps in stomachs," per hunters on forums. Recent posts debate urban deer munching ornamental plants like hostas. No major 2026 news shifts this timeless diet.
TL;DR Bottom
Deer eat 400+ plants led by acorns, browse, forbs, and seasonal mast—adapt to what's abundant.
