This doesn't look like the birds I've been seeing near Crystal Falls, MI in the Upper Peninsula. The ones coming to my feeder seem larger, darker (more dark gray, close to black) and have pale yellow epaulets on their wings, just as the red epaulets are on the red-winged blackbirds. I haven't seen them with any red-winged blackbirds. Could they be the same as those from the Argentina-Brazil-Chile area?
