When I first got started , I never read or heard of toms doing anything but gobbling, spit n drum, alarm putt and fighting purr. So one morning ,just after making some soft yelps I hear this CLUCK,,, CLUCK ,,,, CLUCK. I turned my head slowly toward the direction of the call to see this 1 1/2 year old jake walking down a hogback ridge with his head down low and he showed no color in his head , just grey/blue like a hen. At first I thought it was a hen , except it was so big. then it got to a point where I could see the 7 inch beard. Even now I can recall thinking about how terrible the hen sounded, just before I saw the beard. That bird covered about 100 yards after it began to cluck, and it clucked right up to the gun shot. I first learned the gobbler yelp from a recording. During scouting last spring we heard more toms yelping than any other call. I imitate the yelp and cluck best on a mouth call by letting it lie loosely on my tongue and gently forcing air up as I humm, opening and closing my mouth in proper cadence. The cluck I just open and close with a little more quickness in the movement of my mouth. Like I have mentioned in other replies/posts the 2001 Fall issue of T&TH is a gem to hold on to for the info it contains on fall gobblers . hope there is something here to help. good luck good hunting ''ostt''
