Thanks for the feedback. We are in a subdivision, so I don’t have to worry about spooking horses. And traffic wouldn’t be a problem - we live at the end of the cul de sac, surrounded on two sides by woods (which is where the wild turkeys hang out). The turkeys sometimes do a walkabout through the cul de sac, and the neighbors are used to watching out for them.
The hawks and owls haven’t managed to thin the turkey population much, so I don’t think they would try to take on a peacock, esp. with the number of smaller birds around here (we occasionally find a pile of feathers near our bird feeders, and once saw a hawk feeding on one of the doves it had ambushed near a feeder).
As for vehicle damage, we always park our cars in the garage, and keep the garage doors closed, so I don’t think we would have to worry about that issue.
The noise probably wouldn’t bother us - we tend to keep all the windows closed all the time, and our bedroom is on the upper level of the house.
As for the neighbors - we have had to put up with their barking dogs for years, so I don’t think I would have much sympathy for them having to listen to a peacock screeching. I might worry about the peacock scratching the paint on their cars, though. But all the neighbors that leave their vehicles outside, also have dogs, which I would think would deter a peacock from hanging out near their houses.
I am thinking that if it would assimilate into the turkey flock, it would act sort of semi-wild, and not hang out all the time in our yard. Or is that pipe dreaming?
