Out here in PA, squirrels can be bad and they also chirp and bark at everything as you see out west. Blue Jays are the worst and I have between two and four pair around all the time. I am regularly scolded and announced far and wide, especially if I hunt from my stands along the edges. It is sort of funny though, when a Blue Jay gets close, I tend to react like it was a deer and freeze until the bird moves on.
