I need to do more research on them. I won't mind the noise. My husband hates loud noises, but we don't hear much noise if we are inside. They only do it during two seasons, but that is a while, LOL. There is one neighbor who is near us in the back, but they are gone a lot.Oh..not sure about peacocks. That's a bird you need to know for sure isn't going to bother a neighbor..or you!
