Nice capture. Closest thing to a water bound "bird in flight" I've seenThis was the first time I've seen ducks propelling themselves across the water surface. They moved quite fast. There were a number of them and they appeared to be trying to catch up with mom. I assume they couldn't fly yet, but I'm not sure. As usual, I wasn't ready for the action. These were the only two shots that weren't unusable, notwithstanding the distracting log in the background.
Very nice shot of a Sanderling. Canon hit a sweet spot with the RF 100-500mm.
