My father likes hunting those pressured or spooked birds. Last year (or the previous) he started hunting a bird that showed up a week or so into the season. Every time he'd call the tom would go the other way. He finally shot it the last week and found the fan was a mess, looked like someone had shot at it and scared it over the creek. He had shot another long beard in the middle, but was fixed on that bird. He usually get his focus on one bird and hunts it until he gets it or runs out of season.
