Highlighted months are when purple finches are expected in Illinois. The edges of the window are the interesting weeks — first arrivals and last departures vary most from year to year.
Getting ready before they arrive
The week before October is the time to act. Have feeders cleaned, filled and out by early October — the first purple finches into Illinois are scouting for reliable food, and a station that's ready early gets added to their route.
Through the winter, consistent food matters more than variety — birds map dependable stations into their daily routes and rely on them hardest during cold snaps.
What purple finches eat while they're here
- Tree seeds (ash, elm, tulip poplar)
- Black-oil sunflower at feeders
Purple finches are irregular winter visitors south of their breeding range — numbers swing year to year with northern cone and seed crops.
