Donia,
My theory isn't that the flyway has so much shifted west as much as we have re-distributed the birds on our flyway. I started hunting ducks in the delta in the early 70s and the only fields that flooded then were from rainfall. Nobody pumped up a field! There has been so much developement for duck hunting along the MS River all the way up to MN. I just think that our birds have been scattered, shortstopped, etc. The birds out west are concentrated on the very limited water resources. They stack up on rivers that we wouldn't even call a creek. More like a ditch! They load up on small bodies of water that are plentiful and only retreat to the big bodies when it freezes. They just stay concentrated more out there, like it use to be here. They dry feed because they have to. There aren't many marshes or swamps to feed them in. I'll tell you what though, where you have one, it's loaded. That's the reason that you only have field ducks out there too. Mallards, pintails and widgeon. Every now and then you may see a teal but not very often. Those ducks are just programmed to feed in a dry field just like ours are programmed to feed in a wet field. It takes special coditions to get ours to dry feed. A prolonged freeze prior to mid January will do it every time. They just don't want to go any further south for some reason and I've never understood that. I've seen pairs of mallards taking turns sitting for two hours on a spot in milo fields in OK with 3 inches of snow and ice to thaw out a spot just to be able to scratch up food. Never understood why they just didn't fly to the TX coast but they didn't. JMO!
