Five images, the first four consecutive (no's 74,75,76 & 77) and the last one (81) after a few misses. All were taken at 9:22 AM at 10 FPS and a shutter speed of 1/2500; hence the shots were taken 0.1 seconds apart. I was surprised to see that for the first four shots all the consecutive flight poses were wings-up. This made me wonder why I got no wings-down flight poses during this short take-off to landing series. Surely, there must have been wings-down poses during the take-off. Perhaps my frame-rate was synchronized with the wing-beats per second of the bird??? I was not able to find any info on the wing-beats per second for this bird. Total time lapse from the first to the last image was 0.4 seconds. Any thoughts on this appreciated.
