Deer in Illinois: Where to Look and What Signs to Watch For

White-tailed deer are widespread in Illinois, but your best odds are in areas with a mix of forest and open fields. The Shawnee National Forest in southern Illinois, as well as state parks like Starved Rock and Mississippi Palisades, hold healthy populations. Deer also frequent agricultural areas, especially near corn and soybean fields. Start with Illinois wildlife areas for a full list of public lands.

Deer are crepuscular, meaning they feed most actively at dawn and dusk. During the rut (October to December), they may be moving at any hour. In hot weather, they bed down during the day and move more at night. Plan your spotting trips for early morning or late afternoon for the best odds.

A beginner can start by looking for hoof prints that are heart-shaped, about 2-3 inches long. Deer droppings are small, oval pellets. Look for rubs on trees where bucks have scraped bark, and scrapes on the ground. Trails through tall grass or woods are also good clues. For more details, see our deer identification guide.

Deer are herbivores. In Illinois, they eat acorns, corn, soybeans, clover, and woody browse like twigs and buds. Knowing what they eat helps you find feeding areas. Look for oak stands in fall or crop fields in late summer. For more on deer diet, see our deer biology page.

Fall is prime time due to the rut, but spring and summer offer easier spotting as deer are less pressured. Winter can be good because leaves are gone, making deer more visible. However, they tend to yard up in dense cover during deep snow.
