I agree with what has already been said here on roosted toms/turkeys. They will change sites for many reasons,weather is a big factor,the second biggest factor is hens. The other is predators! Here in the northeast you can put a bird to bed and come back in the morning and set up and find that bird is 100-200 yards away,during the night for some reason they left the roost and went to another roost,my only guess is predators! Raccoons are the biggest threat to turkeys here,they climb trees and will take a turkey off the limb!
I also realize that out west birds have a larger area to travel and follow hens because of the amount of competition from other toms. That they have to stick with the hens,so if a hen is searching for food,she could drag toms miles away from the roosting sites. My suggestion is locating the hens and you will find the toms,food and nesting sites are the main priority in a hen,so these are the driving force that cause hens to move from one location to another,which in turn makes the toms follow!
Weather is another factor,cold,windy,stormy weather will make them look for thick stands of timber,fur trees here in the east,open hard woods in nicer warmer weather. Out west I would say valleys that are sheltered or provide some shelter from the elements!Or just below ridge lines that protect from strong winds and rains! Good luck in you hunting and hope you find some answers that work to help you find the birds and increase your success!
