Honestly, Slobodan, i was a bit taken aback when I saw the image wondering the same thing. The data says I shot it at 7:58am, f:/10 @1/1250 Shutter priority at 640 ISO. I did shoot it from a moving boat which I think tosses the perspective thing right out the door but if you look closely, they are all three pretty much aligned but because of the scale of all three significantly different in size, the Heron, the largest appears closer than the King Bird, but I think more so because of the size differential. The dragonfly, as I stated was pure serendipity falling in the same alignment.
