Oh boy, oh boy... my favorite subject!
Lots of good stuff and all of it is true to turkey hunting. You guys done this a few times before, huh?
Calling during roost time is only one way... a few soft hen tree yelps, VERY softly. Just let him know there's a gal in the area. Sometimes I don't call at all before fly-down. It's amazing just how well they can hear and pinpoint sounds. If you're too close, it may be more detrimental than it's worth. Don't forget how sound travels, when he turns towards you on his roost limb, he will sound closer than when he turns away from you. Very important to be patient and listen to more than one series of gobbles to pinpoint location if you're runnin' and gunnin'.
At fly-down, I just use my gloved hands slapping against coveralls. And then a few yelps to see if there's any interest. All depends on how many hens are around, where they're headed, and what they're doing.
Got to get out there before season and watch (if you can get a high viewpoint) or at least listen as to where they go after fly-down. Knowing your hunting ground terrain is a MUST, so you can visualize in your mind just where they are. As the season progresses, you will notice defined patterns of certain birds going to the same place every morning... some have favorite strutting places where they begin each day, and these birds are usually the dominant ones.
Best to have at least two different calls... he might not care for one, but the other just might do the trick. I have found that extreme cutting soon after fly-down can work effectively (give enough time where you know most of the hens have had time to congregate, maybe 5-10 minutes). Use different calls to sound like many different hens. Most cases, if it doesn't work it's because they have plenty of hens nearby already.
If a bird goes off unexpectedly during mid-morning, I'll let him know I'm there and get him to respond a few times, then shut up and make him think it's time to get over here before he loses her. If you keep right on calling, he'll hang up most times. Best to stay shut up and make him find you. He may have been 200-400 yards away to begin with, but don't think he doesn't know EXACTLY where your call came from.
Then again, I've had mature toms sneak in (all crouched down, puffed-up a bit, no strutting or gobbling). Mature birds, but probably not one of the dominant ones. Don't let the wind keep you in bed, I've seen birds strutting out in open fields where their tails were catching wind like a sail and could hardly stand up straight.
Decoys... set 'em close, make sure there's a Jake in the group. I've had birds in late season get all over a Jake in the setup. Most times, they prefer to challenge the tom decoys before even thinking about approaching the hens. I've had them circle a decoy numerous times without getting spooked at all. Be patient and wait for the best shot, he'll stick around for awhile before figuring out those dekes are dumber than he is.
Our state doesn't allow turkey calling before the season opens... good idea, no reason to educate them before killing season rolls around.
STRING TRACKER... can't emphasize this enough. No matter what arrows or broadheads you're using, there is a good chance that turkey can cover a lot of ground before succumbing to even a great shot (except a head shot, which I think is a very low-percentage shot to take anyways). They can hide in little to nothing cover... the string is like Hansel and Gretel in reverse. Hit one last year a bit low, well... a lot low. Sliced his thighs, he got up off the ground and tucked that arrow up in there and flew off with it, string was just zipping out of that canister like a baitcast reel smokin'. Bird landed about 300 yards down the line and ducked into heavy cover. Would've never found that bird to finish him off if it wasn't for the string-tracker.
OK, I'm done now... good luck to all in your turkey hunting mis-adventures this spring.
These photos ought to get you guys riled up some... taken in Iowa on April 24th, 1983 with my Yashica 35mm before anyone ever heard of a digital camera, LOL. Titled "War Dance at Dawn" and "Gallant Gobblers".
