I love that you did this one in b&w -- excellent choice!. I'm fascinated by the dock with the picket fence and the wonderful reflection of the fence. I'd be curious to see what this looks like cropped so that you just see the upper left quadrant. The gulls and the floating birds are marvelous as is the dock and sign. (the rest is great, too, but that upper left area is truly wonderful!) (not voting, just commenting)
I love the commotion. I wish the plaque on the dock tied to the challenge or otherwise added another layer to the story. As it is I think I'd prefer that the dock wasn't in the shot at all. Still, very nice shot.
Wonderful assortment of poses. I particularly like the gull who appears to be hovering and looking at me with his head cocked to one side, and the Grebes ignoring their nosy neighbors.
