What owls are most common in Illinois?
The Great Horned Owl is the most common and widespread, found in woodlots, parks, and even suburbs. The Eastern Screech-Owl (gray and red morphs) is also frequent in wooded neighborhoods. The Barred Owl prefers mature forests near rivers, while the Barn Owl is rare and mostly restricted to southern Illinois grasslands. Look for ear tufts (Great Horned) vs. round head (Barred) and size - Great Horned is much larger than a Screech-Owl. For more on their distinguishing features, see ourowl species in Illinoisoverview.
In Illinois, owls 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.
Where in Illinois do people usually spot owls first?
Start at forest preserves with old-growth trees and water. Good bets include the Shawnee National Forest (southern Illinois) for Barred and Great Horned, and the forest preserves of Cook County (e.g., Palos Preserves) for Screech-Owls. Prairie areas with scattered trees can hold Short-eared Owls in winter. Check ourIllinois wildlife guidefor a full list of locations.
What is the best season and time to see owls in Illinois?
Late winter (February-March) is prime for Great Horned Owls as they nest early and become more vocal. Barred Owls call year-round but are most active at dusk. For migrant species like the Northern Saw-whet Owl, October-November offers the best odds. Always aim for dawn or dusk; owls are most active in low light. A calm, overcast evening can extend their activity window.

How can you identify owls by their calls?
Great Horned Owls give the classic five-note hoot "Who's awake? Me too!" Barred Owls sound like they're saying "Who cooks for you?" with a descending laugh. Eastern Screech-Owls produce a soft trill or whinny, not a screech. Learn these calls before you go; many sightings start with hearing first. If you want to test your ear, try ourowl call quiz(coming soon).
What should you look for when owl watching?
Look for whitewash (droppings) on tree trunks or under branches, and listen for mobbing calls from smaller birds. Pellet piles at the base of a tree are a strong sign of a roosting owl. Bring binoculars and move slowly. Never use playback calls during breeding season (Feb-July) as it stresses the birds. For more tips, see ourethical birding guide.
