观察细节
Small ducks, overall dark in color from a distance but with light speculum. Very fast wingbeats and fast fliers. Would come in high, but once they turned to the west they dropped down to near the water surface and flew feet above the waves reorientating from a cohesive flock to single file flying. Fly-bys from the north, flying to the west out beyond the breakwall. Came by in 11 separate seen groups averaging 60-80 individuals, with smallest flocks of 20 and 30; first seen 70 (1243PM),80,80,80,60,70,60,30,20,60, last seen 50 (315PM). Seemed to pick up more after the front had passed Michigan City and the wind began blowing from the north/off the lake, although they were being looked for more then too. 660 seen in @ 2.5 hours.
