Have you ever wondered why from time to time that old longbeard will gobble at 1 call and not one more? How several occasions have you been sitting within the woods calling to a bird that knows you’re there, only to get no response?  So you choose to try a diverse call and you lastly get a response.   The answer why, may possibly be as basic as the frequency or pitch of the call your making use of.
A few years ago there was an introduction of greater frequency calls to the marketplace. This was no coincidence. Through the mid to late 1990’s several turkey biologists were beginning to know far more concerning the wild turkeys hearing. Testing revealed that calls within the 12,000 Hz to15,000 Hz ranges received much better responses from the turkeys.  Biologist also found that calls inside this range are heard significantly better by the turkeys at distance. 
A spectrogram could be the instrument that turkey biologists employed to measure the Hz of  wild hen turkey calls. Amazingly enough they located that the hen turkey can reach notes up in the 15,000 Hz range.  These notes had been the discovered mostly when the hen was “cutting” (brief sharp erratic staccato notes, a typical call heard through the breeding season) and was really excited.  With these findings they decided to continue testing 
Not satisfied using the 1st round of high frequency testing, in 1996 turkey biologists brought the testing towards the field.  They applied calls inside the five,000 Hz,    10,000 Hz and 15,000 Hz ranges.  Every of the calls had been regulated to the identical decibel output and discovered that the turkeys responded well whether calling at close to and far distances.  Even so they did note that the turkeys responded greater towards the greater frequency calls and as soon as they responded to the greater frequency, they wouldn’t respond to the lower frequency call again.  As soon as they heard the high frequency calling which is all they wanted to hear.   
The field testing was carried out over 270 times although obtaining more than 90 unique responses.  The turkey biologists were in a position to calculate that 39% of the birds responded to the calls in the 5,000 Hz range, slightly additional than 45% responded towards the calling in the ten,000 Hz range, and an astounding 88% answered the call inside the 15,000 Hz range. 
Shortly following biologists reached their conclusions about the wild turkeys responding to the greater frequency sounds, everybody I know, such as myself,  stuffed a few these calls into our vests! These calls are high pitched locator calls which include crow calls, hawk calls, as well as 1 call that represented a peacock.  The turkey calls that produce the highest frequencies are the pot and peg style calls. The calling surface is generally created of aluminum, glass or some other man produced surface.  Couple these type calls having a graphite, plastic, or acrylic strikers and you not only will probably be able to accomplish the higher pitched calls, you are going to also have the ability to run these combinations inside the wet weather. 
A few of the calls I prefer are the Quaker Boy Aluminator, and my new favorite, the Triple Threat.  The Triple threat has 3 different calling surfaces, slate, aluminum, and plexi.  With this 1 call with I now have surfaces in all 3 Hz ranges.  Matched with some distinctive strikers and I’m prepared to hit the woods operating.  For locators I like to use Quaker Boy Crankin’ Crow, and also the Hawk Scream.  Each are pretty high pitched and loud, perfectly created to obtain inside that gobbler’s head.
Prior to you hit the spring turkey woods this year stuff a high frequency turkey call and locator call within your vest to greater your probabilities of finding that tight lipped tom to gobble. Hunt safe, hunt hard, and take a child hunting so that he or she can take pleasure in the outdoors and carry on our way of life.
