Conservation Season

[Sightwindow]

How come, if the birds are wise to the ways of the fields in south Louisiana, they are not still wise to fields a few weeks later in Missouri? No snark intended. I've been on several conservation hunts with actual birds in the area in Louisiana and every one of them was the same: They took a long look at the spread and the loud speakers and ultimately didn't commit close enough to even sky-bust.

Seems like the guys up north bust 'em up good. Wondering what the difference is.
