I am reading a book called "Illumination in the Flatwoods" by Joe Hutto. Joe is a naturalist (and part loonie, IMHO) that imprints himself on a flock of wild turkeys. It's not a hunting book, per se, but it is a book about how turkeys behave, which is what I'm trying to learn about any way I can. It is very educational, and very well written.
One paragraph in particular resonated with me, based on what all you experienced fellas have been telling us noobs:
"A turkey's sensory ability clearly borders on the supernatural. I am astounded by the wild turkey's ability to determine distance and direction and I have learned that a spring gobbler who answers my call from a quarter of a mile awy needs no other sound from me. If he chooses to come, he will know almost exactly from what bush or tree trunk the call came."
Yowza.
