Rounding the tip of the island at Pensacola Pass, I saw two Great Blue Herons about 100 feet in front of me. I stopped the Mule just long enough to pull out my camera, but realized I was still too far away for a good shot. I pulled forward another 25 feet or so, fearful that I would startle them into flying away.
Suddenly, in unison, both herons looked skyward, extending their necks. I moved the camera away from my face and looked up to see what had grabbed their attention. There was nothing in the vicinity which I could see.
The heron in the first position seemed to go into slow motion, walking alway from the shoreline and toward the dunes in a march. The second heron continued looking up and fell in behind the first.
Again, I moved the camera away from my face and looked up to see what had their rapt attention. No planes, no osprey, no gulls, no other people in sight - just two herons in a trance.
