Photographing herons is kind of a fun thing to do since they are such a large bird and so distinctive.  Having got so close to some recently, I have got a lot more photos of them from different angles and this has included some head on shots of them.  I had not appreciated the shape of the head of the heron until getting this view.  The head is narrow, as I had know, but it is tapered.  While I thought the eyes were on the sides of the head, the shaping means that they have more of a forward view than I had realized which is obviously important for hunting for fish and perceiving depth when preparing to strike.  Head on it looks like a very different bird!
