Nope, there is no state where you can shoot any bird on the Migratory bird treaty act without a permit. If you are wondering what type of birds are on the act it is pretty much every single bird native to the US, and no, it does not matter if the bird is Migratory or not. There is no state where you can shoot vultures or buzzards. The only exception that I know of on the act is the American crow and domestic Muscovy, which can be shot freely. I am not a cop who is going to arrest you or a citizen who will report you. I am not mad at you, just wanted to let you know that you are not supposed to be killing these birds or any birds on the act without the proper permits.Well I thought I had heard that. I was under the impression it was just certain states had different laws. I knew in our area Vultures/Buzzards were. I apologize.
BTW, the act also makes it illegal to have any products that were produced by the protected birds in your possession. So no feathers, egg shells, nests, or whatever. So make sure your husband did not keep anything from those birds he illegally killed.
