About 0.4 Second

I had set my camera on a burst mode of 12 shots per second as I walked softly - to the human ear - to the edge of the bank expecting the duck to throw itself aloft, but instead it flipped into a dive, whether elusive or fishing I could not tell but I luckily captured these four photos in a little less than 0.4 second.  I believe it was the Lesser Scaup - which see next post.
