Black-Crowned Night Heron
This is my favorite shot from this day, because it has the most three-dimensional representation of the heron's eye.
I wasn't entirely sure how to handle the crop; the original has more space on the left, right, and above. I cropped out some of the bird, because the gaze works better as a leading line without the right flank. I went back and forth several times on how much of the empty space (it's the water of the channel, rendered completely smooth by blurring) to include. I didn't want so much blank space as to lose the bird, but I also wanted the bird's gaze to be going somewhere. I settled on this (which is also pretty close to a standard rule of thirds composition) as a pretty good balance.
