Blackbird flock-Swan Harbor Farm, Havre de Grace, MD 1/27/12
This is an uncropped photo...I cropped out a small section and tried to count that section, then extrapolate. I estimated that there are roughly 3600 birds in this frame. The entire flock was easily 25 times this number, so it was probably upwards of 100,000 birds, mostly Common Grackles and Red-winged Blackbirds. This was a relatively small flock, compared to some of the fall migratory flocks that stretch for what seems like miles as they pass over in those massive, undulating ribbons. The flocks are staggering when you actually try to put numbers to them.
