When my husband saw this picture he said, "He looks angry".
I told him that wasn't the look of anger.
What you see in the bird's narrow eyed, as-if-they-can-see-through-you look is the look of a fisherman.
He spends most of his life out over the water hunting for fish. He has a biological imperative to stay out there.
He is cold and tired. He is on the brink of death and ruin. Yet when he returns to land (usually to mate) all he can think about is going back to sea.
