I don't get a chance to roost birds as often as I'd like, but when I do I am mostly listening and shock calling. Usually I'll use an owl or hawk when roosting but have used coyote howler. I never use turkey sounds when roosting.
I have killed way more birds that weren't roosted the night before than ones that were, and like I said I don't get out and do it that often, but the feeling of going to bed and knowing you are going after a bird in the morning and you already know exactly where he is, is a pretty good feeling. But definitely doesn't guarantee anything in the morning.
