Walk in a zig zag pattern and listen for the cackling. Stop often. A slow walk will do it. Pen-raised pheasant run more and flush less than wild birds. With more than one hunter use blockers -- Pheasant will break from a field to heavier cover, like a stand of trees. Let one person stand near the trees and the other go thru the field. Try not to shoot each other!

One method I use is to hunta field next to where hunters are working with dogs. What they miss you will kill because they may flush birds in your direction. The one thing I hate happened to me twice this year -- When I left the hunting area on the way out a bird walked across the road in front of my car. Both times I could only stare at it.
