觀察細節
Easily found near their usual location on County Road 45 just south of Yolo County line. (38.906, -121.849) Some had the black forehead of breeding plumage. Foraging in brown field on west side of road, maybe 225 yards out. They were moving separately across the furrows, popping up into view and then down out of sight. This made it difficult to get a count; we estimated 25. Then they lifted off together and we saw there were nearly twice that number. Confirmed by counting in photographs. They flew east toward river and out of sight.
