* Grasses: They graze on a variety of grasses, especially during the summer months.
* Forbs: These are broad-leafed plants like clover, dandelion, and other wildflowers.
* Shrubs and twigs: Deer browse on the leaves and twigs of shrubs and trees, especially during the winter when other food sources are scarce.
* Fruits and nuts: They eat fruits like apples and berries, and nuts like acorns and beechnuts.
While they might occasionally eat insects or small animals like birds, this is not a significant part of their diet. They lack the necessary digestive adaptations to effectively consume and digest meat, making them true herbivores.
