The natural habitats for deer are woodlands, river bottomlands, forest edges, plains, swamps, meadows and farmland. Deer can survive in many different types of habitats as long as there is vegetation and water nearby.
The two most common deer in the United States are whitetail deer and mule deer. Both types are mostly herbivores, meaning they usually only eat plants. Depending on what is available, a deer will eat leaves, acorn, fruit, hay, corn and occasionally birds or field mice.
Deer prefer to live near openings that provide escape cover. These areas are called edge areas and include roadsides, parks and greenbelts. During the winter, deer move to forests with mature conifers because these trees provide protection from the cold and snow.
