As an afternoon of migratory autumn/winter migratory bird photography runs on into sunset and then twilight, it is inevitable that there will eventually be too little light to photograph as I do during the day. But I usually continue until it is virtually dark — to the point that I may need a headlamp to stow my equipment when I finish. During that final low-light period I often end the cycle of increasing ISO and pushing shutter speed, and instead I drop ISO down to the minimum and let the exposure times lengthen, working with motion blur of birds in flight.

We had positioned ourselves near a large flock of geese in a pasture, and they were gradually become more restless, beginning to take off in small groups and leave for parts unknown. Groups tend to depart together, and as they do they take to the air en masse with little or no warning. It is hard to say what makes a photograph “realistic,” but I often feel that these masses of blurry birds suggest the quality of these departing flocks as truthfully as stop-motion photographs.
