I have heard the referred to as many different sounds but the best description is the battery of confidence calls…the cluck and purr. All other sounds can and will bring in thousands of birds but when the chips are down or when those birds are close but need to be closer it is the gentle cluck and seductive purr that seals the deal. I am convinced gobblers hear yelping from every brand of call and these have their place in early morning set ups but throughout the day…how often do you hear strong and consistent yelping? Hens do cluck and purr all day, especially when talking with other hens and when content and safe while feeding. Once I yelp a few times, I may spend the rest of the hour simply clucking off and on and purring, primarily to let that gobbler know I am still here and still content and safe. I think it also tells the gobbler that I am not needing to just run to him but here if he wants to come over my way. I really think a lot of hunters over do it with yelps and cackles which can scare away cautious Toms.
Don’t abandon the other calls but a good slate call with a lucky striker can make the most seductive clucks and purrs and draw that Tom in where other calls scare them away.
Be safe, experiment with your calls and just have fun!
