Having had a large uptick in younger birds being produced the last couple years, I have had far more interaction with turkeys (albeit mostly jakes).
Here are some things I have noticed and put to use.
If the woods are quiet, and you can get one bird to gobble, often times others (that have been quiet) start to gobble as well…
Here are some ways that I have used a gobble call to my benefit:
*Running & gunning. Hunting any area, there are areas that you probably know are more productive than others. Before entering these areas and trying to raise a gobble, I will hit the gobble call several times BEFORE moving on to hit the hen call (from a slightly different location) to raise a gobble. In other words, I am not using the gobble call as a locator, but as a primer…
*When sitting in a productive area for some time, without having heard or seen any signs of active turkeys, the last thing I do before moving to another area is to hit the gobble call, followed by some aggressive hen calls… I have sometimes been surprised at a bird that was reasonable close (one time by a bird in range that I had no idea was there).
*With a henned up tom, I have used a gobble call (or tried to) to create an aggressive response as opposed to a mating response. It has worked, but admittedly not very often.
I have also had the opportunity to watch birds (both that I am hunting, and just observing) from a distance (through binoculars) while calling at them.
Yelping… A “hot-to-trot” bird will often gobble, and often immediately change direction and start coming. I have also seen birds go right into strut without making a sound, and not make any forward motion (probably spitting and drumming). I have also seen birds gobble, and continue on their route (not towards me).
Cutting… Very similar to yelping. Generally an attention getter, and often I will see heads come up on birds. Maybe a bit more likely to get a “shock-gobble.” I have always been more comfortable with yelping, as that is what I hear hens in my area do the most… If I hear a lot of cutting, I will tend to cut more for a response.
Purring/clucking… Interestingly, I have watched birds meandering, and change direction to meander to me… Sometimes with a gobble, generally not. I have been surprised at the distances that a bird will visibly react to such a quiet call (bird stops to look, head comes up, change of direction, half-strut, etc).
With all of the above, I have seen birds not react at all… Often times a tom with hens will gobble, but will not move from the hens. I have also seen hens appear out of “nowhere” and redirect the attention of the birds.
