And the turkeys do move their roosts. A few years ago, I found a roost several hundred yards up a hill. On opening mourning, I park the car in the dark and get my stuff together only to find that the turkeys had moved the roost to a tree next to the road. The tree leaned right over where I parked the car. Needless to say, I woke them up and other cars went by to further make the birds wary.
They flew off the roost before shooting light and I never saw them again.
