For me the best time to locate the birds is in the morning.
I hunt public land in Fla, so we are done hunting at 1:00.
I get to the spots I want to check in the dark. Then I will walk and blow the owl call every 100 yards are so. Once I get a gobbler to answer I will mark the spot on my GPS and keep going, trying to find another one.
Then I will go into the area later in the morning to look around and find the best place to set up, and the best way in.
