Are we looking up at the bird, but down at the waves? If down at waves, why can't we see more ocean behind the back wave? Are we (and the bird) really going to get swamped by that back wave when it comes crashing down on us?

Those are the questions that come to my mind. That is an amazing amount of patience on your part, and I do like the way the waves have a certain type of power, and the froth that you have captured.
