Be prepared to barter. I got permission to hunt birds only, Canada geese and ducks. Those birds make an awful mess of stock water ponds not to mention the crop damage. So that was OK, I'm the scarecrow with a 12ga. In that day and time, they were trying to train a couple of ??? falcons to hunt the local pigeon problem. As we are required to use non-toxic shot for migratory waterfowl (I'm shooting BBB and #2 steel), I breasted the birds for them and for myself and gave them the remains of the birds for the falcons in the winter.
So the farmer switched from peas to oats. The greese and ducks all went away. In August, stand at the field edge for a while = nothing but black bears, lying down and grazing. Not my game.
