Obey all the common rules of gun safety while afield, e.g., always keep the muzzle pointed in a safe direction.
Be mindful of where your hunting colleagues are at all times. Always wear hunter orange, at least a cap, and preferably a cap and vest. Leave your camouflage jacket and Bowie knife in the deer blind.
Maintain a straight line when walking. Sounds simple enough, right? You’d be surprised how many times you have to remind your hunters to “straighten up.”
Scan the ground in front of you for obstacles that may trip you (e.g., a hole or piece of wire). If you sense an impending fall, hold your shotgun “out and up” and hit the ground on your elbows. If you do fall, open your shotgun’s action and check to ensure the muzzle did not get plugged with mud.
Know your assigned “safe zones of fire” and respect them. If there are more than two in your hunting party, do not shoot at birds that flush behind you. Never shoot at a bird that causes you to shoot across or over your partner(s).
When approaching a point, move quickly but safely into position. Walk past the dogs without slowing down. Don’t stop, or begin to “stalk” the dogs on point. This is a good time to remember where every member of your hunting party is. If multiple dogs are on the ground note their locations.
Always approach a pointed bird dog with your gun in the “port” (ready) position (muzzle pointed up) with the safety “on.”
Do not shoot at low-flying birds or at any bird if the guide yells “no bird, no bird.” One way of thinking is “blue sky only;” if the birds are not above the horizon pass them up.
Do not shoot birds on the ground.
If you knock a bird down, mark its location well, but don’t proceed towards the downed bird until all shooting has ceased.
Locate and pick up your spent shotgun hulls. Never leave any trash in the field.
Always unload your shotgun (safely and completely) before getting into the vehicle; leave the action open for easy inspection (I rest much easier when I see an open action). When unloading, make sure the muzzle is pointed in a safe direction at all times (generally upwards and always pointed away from anybody else).
Be especially careful when crossing fences or going under or through dense brush. When crossing fences, unload your shotgun and pass it to a partner, or lay it on the ground (on your cap), then cross through and continue hunting.
