I did notice that there was nothing for the birds to eat where I was hunting. It was just weeds and thorns. Usually they leave a row or two around the outer edges with soy beans and corn. They didn't do that this year. There were corn fields all over the place in the hunting area where I saw the pheasant by the road.
Jimmy, if the corn was combined there should be sufficient grain left for the birds. No combines can get it all. If a farmer can hold his harvest losses to 2% he is doing extremely well. What that means, however, is that 180 bushel per acre corn will have at least 3 or 4 bushels of grain per acre left on the ground. What I don't know about pheasants would fill volumes, but I know combines and, if a pheasant is as good at getting into thick stuff as I have read, they should have no problem finding that harvest loss.
