This state's classification carries no date range for the species.
No wild chukar population exists in Illinois and no general statewide season with fixed dates/bag limits is published (absent from the 2026-2027 Digest's season table). Illinois statute lists 'chukar partridge' among legally definable 'game birds' solely for licensed hunting-preserve purposes: pen-raised chukar may be released and 100% harvested on IDNR-licensed Class A preserves (Sept 1 – Apr 15) or Class B preserves (year-round), under separate preserve-license regulations, not the standard wild-game season/bag-limit framework.
Confirmed absence: no wild chukar population exists in Illinois and no general season is published; chukar exists only under licensed hunting-preserve release permits (Class A Sept 1-Apr 15, Class B year-round), a stocking/release framework rather than a wild population any survey would track.
