Due to my age, job, hobbies, I have lost quite a bit of hearing high tones. Low tones not so much.
I heard drumming this year far more than the bird actually gobbling. 12 out of 14 birds I got came in silent. No gobbles. 6 of those came in drumming. The other 6 totally silent.
They all came in strutting.
And I heard drumming which was driving me nuts only to see the bird 115 yards out. I watched his strut and resultant drum. I ranged the bird as I didn't believe I could hear that.
out that distance.
If you don't learn to recognize that low hum...that sound....good chance you will move at the wrong time.
