1. What types of squirrels live in Illinois?
Illinois is home to four main tree squirrel species: the Eastern Gray Squirrel, Fox Squirrel, Red Squirrel, and Southern Flying Squirrel. The Eastern Gray and Fox squirrels are widespread, while Red Squirrels favor coniferous forests and Flying Squirrels are nocturnal. Ground squirrels like the Thirteen-lined Ground Squirrel also occur in open areas. For a complete list, see ourIllinois wildlife hub.
In Illinois, squirrels sightings usually improve when you slow down and match your first stop to the most useful ID markers and likely lookalikes. Use thestate wildlife huband theroute guideto narrow your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to brush, wetlands, timber, shoreline, or neighborhood cover.
2. How do you tell apart an Eastern Gray Squirrel and a Fox Squirrel?
The Eastern Gray Squirrel has a grayish back with white belly and a bushy tail. The Fox Squirrel is larger with a reddish-brown back and orange belly. Fox Squirrels also have a broader head and a slightly more rounded tail. In many Illinois parks, both species coexist, so look for color differences in direct light.
3. Where in Illinois are squirrels most often seen?
Squirrels are common in oak-hickory forests, urban parks, and residential areas throughout Illinois. Best odds occur in state parks like Starved Rock, Matthiessen, and Chain O'Lakes. Also check college campuses and city parks in Chicago and Springfield. For more on Illinois wildlife sightings, visit the/wildlife/illinoispage.

4. What time of year is best for spotting squirrels in Illinois?
Squirrels are active year-round, but fall (September to November) offers peak activity as they gather nuts. Early morning and late afternoon are the best times for sightings. In winter, look for nests (dreys) in bare trees. Spring brings baby squirrels, but daytime activity remains high.
5. How can you identify a Red Squirrel in Illinois?
Red Squirrels are smaller than grays and have a reddish-brown back with white belly. They have a distinct white eye ring and a thin, often reddish tail. They prefer pine and spruce forests, so look in conifer stands at places like the Shawnee National Forest. Their loud, chattering call is a giveaway.
