I think that a lot of the reason that we are seeing such a decline, is from loss of habitat. The farming methods have changed in the last few years, in that the fields are so clean now. There used to be all kinds of grass and weeds in the corn and soybeans. I think another main reason is that we have experienced several wet springs and that is pretty hard on new broods hatching, then throw in that tough winter and it is pretty hard to bounce back. I don't think that it would take to many nice springs and mild winters to bring our numbers back up. Here in the area that I live we had a nice spring last year and we saw decent numbers of birds but it is not looking good this year.
