RE: What do Turkeys do when............
From my own personal experience, turkeys definitely DO gobble at thunder. One of the times we experienced this, we sat it out because there were at least a dozen gobblers in the hollow below us and they were gobbling in strings of 25-30 gobbles at a time. Dang birds came in strutting and stayed just out of range. Rain--while not fun to hunt in--can help you. It helps to silence your sneaking around in the woods and often prompts them to move to fields. Knowing that in advance, you can greet them there in a most rude manner!
