Hearing didn't help

The old gobbler rattled the woods for 15 minutes from his roost.  When he flew down, I distinctly heard him gobble two more times.  Dad never heard him at all.  But hearing didn't help.  That gobbler marched right to Dad's calls and his decoys and Dad put him in the freezer.  I heard him very well, but he ignored my calls and decoys.  It was Dad's 65th wild turkey harvested.  He's only 50 ahead of me.
