Down the Gullet

Last post in this Heron series with the fish. I appreciate all the feedback I've gotten. Here the heron has all but the tip of the tail from the fish in his gullet. I've got a few shots that lead up to this when he was swallowing the fish that you can see his eyes dilate and bulge, almost as if he was thinking "uh-oh". I was also trying out different f stops, so that explains the f/16.
