Young turkeys,little huntin pressure can add up to alot bolder birds!No question pressure makes them much more spooky and wise to hunters!Jim makes a good point because they do feel more comfortable in numbers especially during the fall.But with that said I have had on a # of occasions during the spring been working a flock or even a group of two year old gobblers where one of them actually made me out or saw me move but because the others didn't and weren't acting nervous the bird calmed down!So Jim I believe your right on the money also!
Monarch isn't a butterfly it's the King of the Spring!
