Excerpt from Ohio State Department of Natural Resources:
PHEASANTS TO BE RELEASED AT 29 PUBLIC HUNTING AREAS STATEWIDE More than 15,000 ring-necked pheasants will be released on 29 public hunting areas across the state this fall, as part of a seasonal effort by the Ohio Department of Natural Resources (ODNR) Division of Wildlife to enhance hunting opportunities for this popular game bird.
Ring-necked pheasants will be released on the evenings of October 24 and 31 (both Fridays) in anticipation of the following weekends' small-game season for youth hunters. Releases will also take place on the evenings of November 6 and 14. The final release of the fall is scheduled for the evening of Wednesday, November 26 to increase pheasant hunting opportunities during the Thanksgiving weekend.
Pheasant hunting season opens statewide on Friday, November 7 and remains open through January 11, 2009, with a daily bag limit of two rooster (male) birds. Hunting hours are sunrise to sunset.
