I live in semi-urban/semi farmland area of the County. I live next to 5 acres of land that has been found by a flock of pigeons. I have a plastic hawk on the roof which is doing a semi good job, but I think that trimming the flock may be needed. Can I use .177 on these? I have rifle and pistols, but most accurate would be the scoped rifle. If a neighbor sees me and calls the police, would/could I be found out of legal use?
