I have the Woods Wise screaming peacock.I don't think it scares them but cant say for sure.It did help prevent a possible shooting accident though.Once while doing some hen calls another hunter used it while approaching my position.I used it back at him.I don't know which of us was more surprised by that.Anyway right then I figured it was time to move on.Just as I got up a hen launched off the hillside right above between us.Though illegal to shoot hens here in the spring it was good we each knew the other was there just the same.
