RE: Birds right above me on roost.....
You did what you had to do in sitting absolutely still for all that time. I bet it was agony!!
I' d say that if it is a regular roost site, they' ll be back to use it again, though not necessarily tomorrow. You' ll have to locator call in the morning and try figure out their flydown landing zone, and set up there, if you find their roost site.
A friend told me of a time in the Black Hills when he and his buddy set up in the early morning darkness on some roosted the night before turkeys, and, as daylight came, learned that he was sitting under the roost tree, because it was raining turkey poop!! They had no luck, either.
I wonder if a stealthy belly crawl away out from under the roost tree and silent relocate on the opposite side of the way you crawl away when out of sight might not work, if you decide to do that at the first realization of where you are. I know the turkeys wouldn' t want to fly down to a predator like a coyote, and I wonder if they wouldn' t remain in the tree if they saw a predator crawling away. I' d think they would fly the opposite way from where they last saw the predator, when they decided to fly down, so if you circled around, maybe you' d be where they flew.
I' ve never done that, and I think I' d probably sit stock still like you did, because I was within 50 yards of an unknown/unseen hen at flydown last Wednesday, and when she clucked, that' s what I did--sat there as perfectly still as I could.
Good luck tomorrow!!
