Wildlife nostalgic mood

This grey heron somehow evokes nostalgia, memories of times past.
I shot this impressive bird at 600 mm, f/6.3, ISO 640, 1/80 s. It is amazing how we can shoot handheld at 600 mm as long as we are at 1/80 s in rapid-fire mode and still get a couple of clear shots.
The heron was really cooperative, as he/she was still all the time, maybe, as I have said, thinking about life. :)
