ARCHERY HUNTING
No person shall hunt big or trophy game with bow and arrow or crossbow during a special archery hunting season without first obtaining an archery license and the appropriate hunting license. Archers must abide by the regulations established for the special archery season and the regular hunting season. Archery equipment and legal firearms as deemed by law may be used to hunt game during all hunting seasons except where Wyoming Game and Fish Commission regulations specify otherwise. As of 2007, it is lawful for an archer to have a firearm in possession while hunting during special archery seasons and in archery only areas. No special archery license is required for hunting game birds or small game with archery equipment; however, archers must first obtain the proper hunting license for the species to be hunted.
