Born: it is had to say. I have a place I hunt,and know (like you ) there are birds there. we see them and durning deer season we see a lot of birds. for the past 2 years we have not heard a bird gobble yet.3 years ago, at most any morning I would hear 5 to 6 birds gobble.then past two nothing.I have saw the birds in off season , so I know they are still there.?????????
as you, we are stumped.

turkeys are hard to figure ( the way they talk that is). one day they will gobble 50 or more times , then the next day not a word.

you have a good question, I just don't have the answer.
