Going to need alot more links to cover all the countries and state laws, and don't forget the pictures and movies could be from a archive.

But then again people should be responsible enough to know what they can shoot at at what times.
If people brake it maybe we as a community should flag them and let the mods give them a warning and maybe a posting ban for a month or so?
 
The chart listed above (http://www.fishyfish.com/air-gun-hunting-regulations-chart.html) is way out of date. As suggested, look up the laws for the state you're going to hunt in, even though you've hunted there in the past. After all, hunting laws change from time to time. New Mexico is a good example. The law now specifically allows the use of airguns for all non-game species, and a few protected ones. 

As for protected species..... All animals could be considered pests under certain conditions including federally protected ones like crows and starlings. I have no issue with shooting crows, starlings, house sparrows, doves (any variety), and black birds n and around the feedlot where I have permission to "plink". As I've said before, an average bird eats about 150 times it weight per year, and when there are literally thousands, shooting is about your only salvation towards profitability. 
 
Pa. its simple.. No air guns period..... I have been writing the Game Commission, but no answer yet.
Pa. is living in the dark age. . These small little broken town homes spread out through the coal region will be like that for the next 100 years.
I moved here in 1972 and in that time I have seen very little change, other then some casinos coming in ,very sad
Good Post AJ, we all get caught up in shooting , this is a great reminder, watch what you are shooting and are you allowed to use air guns. I am sure there are Wardens checking out Forums and You Tube. Here in Pa, Wardens have more power then State Police
 
I think it is a good idea. The darn warden does not care if you knew or not. He will assume you knew as will the judge. Fines and penalties can run into the thousands of dollars and require the forfeiture of your gear, even your vehicle sometimes. Game laws are serious business. In some states the Game Warden is the only officer of the law who can enter your home without your permission and without a warrant. 

If for example, he saw you shoot a migratory bird, say a Dove from your back porch. Even if you carry it inside, he can come in and take it as evidence without a warrant. At that point he can confiscate all your shootin' irons until the trial. So it is a good idea to know the law in your state.
