Dale,
Went to college up in New Wilmington. The Amish farms then where fairly thick with wild Pheasants and the adjacent edge covers had them. The Amish up there haven't changed their farming practices. Last time I was up there the edge covers looked the same or at least more than adequate. Have hunting friends-Bird Dog people-who live close by and according to them some of the Mercer Co swamps hold some remaining wild Pheasants. Other than that it is put and take.
Same with Doves. Some fields would have 2-300 Doves trying to get in and feed. You can find them today, but usually not close to those numbers.
IMO, something other than habitat is and has been going on.
