What are some of the most common mistakes people make when calling? I think I call too often and too aggressive sometimes.

Perhaps the biggest mistake is calling with an noticeably unnatural rhythm. You don't have to be a "great" or textbook type caller if you sound like a real turkey.

Calling too loud; when the gobbler is in sight and when he's still on the roost.

You got it bigtom, i think it is calling too often, and to loud.

.CALLING WHEN THE BIRD IS NEAR YOU,IVE KILLED MORE BIRDS JUST
SHUTTING UP THE LAST 70 YARDS OR SO.....

I would say calling too much can be a mistake but I think the phrase "over calling" might be a little over used. I think it is alright to call quite often. It is the volume and aggressiveness that can be the biggest mistakes. I know there are definately times to shut up...especially when he's close...but alot of times I use soft purrs, clucks, and very soft yelps and do it quite a bit. I think you just need to find what the turkeys seem to respond to best. IMO "over calling" is calling too much, too loudly!!! Not just calling too much.

If the birds responses or lack of responses are not dictating your calling than your making a mistake!!!

I quit using mouth calls for that reason. It was too easy for me to may "just one more call". If I have to move my hands to call, I'll think about it longer.

Okay here is my personal non-expert for what it’s worth opinion. I think that turkey’s use inflection in their talk just as we humans. For example you can say the word (oh) and mean many different things. It can be a question or it can mean indifference or surprise and it’s all in how you say it. That’s why I am not a big fan of box calls you can’t put much if any inflection in your call the way you can with a mouth or slate/glass call. Anyway I listen to the wild ones and try to put that in my calling. IMHO

Kase,I agree 100%.I call it puttin feelin into my calls.
