re: What do you attribute the migration change to?

For those that think the cropping is the #1 cause, and were around long enough to actually see those changes, my question is this: did the birds come down regardless of snow cover prior to the mass changes in agricultural practices?

I can understand the argument that more food is on the ground now because of no-till, but I would still think weather would drive the migration. But I wasn't around prior to all the mass changes, so I can only speak for what I've seen and (Think I) know.

ETA: Just saw the post above that gives a pretty good explanation, although I still tend to lean weather then ag.
