I know all things change as does the reaction of the birds to anything in their habitat. I really think, that with the cover I hunt here, there are zero birds that you will be within gun range of, without them knowing it. Between the sounds of the dry cover, the dog, birds running in front of us, flushing birds and the sound of an occasional shot blast, they know you are there, I don't care how quite you are. Maybe in lush green grass with no dog and you wearing socks only, maybe you could get close to one. I don't think some folks are aware of just how perceptive pheasants are or think they use their camo as a defense means to avoid detection. If they didn't, the dogs wouldn't be very useful. With that said, I use a light mouth whistle for the dog generally.
