I try not to make any noise at all. I want the deer perfectly relaxed when I release the arrow. However in MI we can bait, so I usually throw four or five apples or something on the ground where I think the deer will be. This usually stops them right where I want them and gets them looking down or something. I'd be afraid to whistle or something and have the deer look right at me. From what I understand they have independant parabolic hearing and can locate sound very quickly.

If I had to though I would probably just try to imitate a grunt call with my mouth. I have thought about taking a turkey diaphram with me and chirping with it. That's about the most realistic sounding call I have.
