I agree with you on one point.... There are too many hawks, owls and other birds of prey. They need to be thinned out if there is any hope of reestablishing a wild pheasant population or increasing the population of any small game animal. As far as your "constitutional" argument... No state is going to secede from the union for any of the reasons you have mentioned here or in your PA anti-gun thread.
The birds of prey are protected by federal law. I know it is becoming more common for some to shoot redtail hawks and such, actually always has been depending on the area in question and what type of poultry or pigeon or whatever bird people raise and have the hawk population raise an equal amount by feeding off these raised birds. Will I report someone I suspect of killing a hawk? No, I'd thank him for taking the risk and saving a few more of the small game animals that have been almost wiped out in our state. I do what I can when I farm food plots to increase the odds of these small game animals surviving. If each of us who owned some fields would create some cover and habitat we would greatly increase the odds of successful reintroductions of species and increase the populations of others.
