I have never seen woodies in the field, or perhaps you mean field as on the water. I've seen them setting on logs, branches, can't figure how they do that on branches. But they will decoy to just about any waterfowl decoy I've seen. Or, for that matter, no decoy at all. I've seen over a hundred flock to a small pond at dusk in groups. With their craw chocked plumb full of acorns, more than you can hardly keep in the palm of their hand. They are IMHO the most beautiful colored drake of all. And I have quit knowingly shooting at them. They taste to me, better than any save Cans, whose flavor to me is par none, of course as always IMHO only.
