觀察細節
Minimum estimate, possibly as many as 350. Several flocks of 50-100 continuously moving back and forth between pond and adjacent pasture. Minimum count accomplished by observing three separate flocks arrive at pond in short succession. Distinguished from Red- winged Blackbirds by bold white epaulet border on males, sharper, more acute bills, and distinctive vocalizations.
