This past Friday I photographed this Great Blue Heron (Ardea herodias) at Occoquan Bay National Wildlife Refuge in stealth mode as it attempted to sneak up on some potential prey. At other times, the heron walked through the water with its head held high. It was a fun little photo session for me, though I suspect that the heron wished it were more successful in catching some fish.

I love these with that gorgeous blue water, Mike. The GBH behaviors are fun to watch, especially when they are actually moving!
I chuckled when I read your comment, Ellen, because I have spent endless hours watching motionless herons, waiting for them to strike and hoping that I will be read to react. 🙂
