Fall hunting can really test your patience. When you locate them, it can be easy but when you haven't located them...then that's when patience will pay.
The weather here has been terrible and both Doris and I have been fighting an upper respiratory infection for the last 2 weeks. It's left us very weak and both of us also have reduced hearing due to a continued blockage. I can't hear anything out of my right ear currently, so hunting has been pretty much out of the question. Yesterday, however, we both just had to get out of the house.
It was very cold and windy, as it had been for the last 3 days. We hit the bottoms in hope of finding some birds there. No luck. We went to a know soy bean field but it had not been harvested, no birds. There is no winter wheat on this property, so we just spent some time sitting, calling, sitting...
We had 2 beautiful deer walk into one section of woods and come within 15-20 feet of us without ever seeing us or catching our scent.
We'd walked a lot, sat a lot, called a lot and no luck, so we moved to another location where our neighbor has seen birds going into the woods to roost for the last month.
I sat in that area until after dark and not one bird decided to roost there that night! Patience. There's really nothing else that works in the fall.
I also agree with Mark that sometimes in the fall a box or some other friction call can be quite beneficial, especially when the wind is blowing. Those calls can make sounds that will carry further than mouth calls.
Lastly, even though our neighbor's information did not pay off last night, I'd sure ask anyone who's near the land you're hunting if they've been seeing birds. They may just be able to help you out.
"If he's out of range, it just means that he has another day and so do you."
