I’m a big fan of both roosting and “pre-hunting”. I pre-hunt all of my spots when I’m taking out new people, or really only have a day to hunt by simply heading out mornings previous and being still. When pre-hunting, observe, study, and take note of everything that takes place that morning. When my days off at work/school were more limited, I was a fan of taking off two days before the season, then only 3 during the actual season. Amazing how much more observant you are with no gun/bow in your hand.
As for roosting, I put less of a priority on it, but have learned alot of information over the years that has been crucial to each and every following morning’s success. Even if birds roost in the same spot year after year, they don’t always roost in the same direction, trees, or with the same company. I’ve bailed on groups of birds for other land simply because the hen:tom ratio was poor with that group of roosting birds. Or, I simply decided to take a blind to the closest likely strut zone, put the calls down, and wait them out.
Either way, the more information you can gather on the specific birds you’re hunting, the better off you’ll be come game-time. The more and more I hunt them, the more I feel it’s about understanding the personality of the turkey you’re hunting. I think simply being out there with those birds long enough gives you insight as to those personalities.
