Can I legally use a .22 to shoot forest grouse or is it shotgun-only?

Forest grouse represent an exception to the rules governing hunting of most game birds. Forest grouse may be taken legally with shot, rimfire, centerfire or muzzleloading firearms as well as with bow and arrow. Rocks and sticks are allowed for forest grouse. Unlawful are traps, snares, nets and crossbows. Air rifles and pellet guns are not legal. The reason for the liberal rules about taking forest grouse is that the birds are traditional camp food for big game hunters. Big game hunters often do not want to fire a loud firearm in their hunt area.
