Iroquois County State Wildlife Area is the one northern site of the four Illinois sites with extended controlled pheasant hunting seasons.
Here is the word from the Illinois Department of Natural Resources:

Hunters can make reservations now for additional hunting opportunities. The four sites with additional controlled pheasant hunting are the Eldon Hazlet State Recreation Area in Clinton Co., the Iroquois County Conservation Area, the Jim Edgar Panther Creek State Fish and Wildlife Area in Cass Co., and the Wayne Fitzgerrell State Recreation Area in Franklin and Jefferson Counties.
