I have talked to the local game warden in the IV (Jason Green).....He told me that it was a misprint in the regulations.....Feral pigeons have always come under the regs of USDA (Feds).
Legal Status per USDA
"Feral pigeons are not protected by federal law and most states do not afford them protection. State and local laws should be consulted, however, before any control measures are taken. Some cities are considered bird sanctuaries that provide protection to all species of birds".
So, your rolling the dice so to speak. Depending on the warden and his interpretation of the law is no bueno in my book......Me personally, I don't shoot them.
