Yes, this is as far as I can figure a Great Blue Heron. I'm not sure why he has different plumage than the heron I posted Saturday, maybe he's just older. Not a perfect picture, the focus is off a bit, I think it was the wind in his hair. He was hanging out on Snow Goose Pool on Assateague Island, VA with some ducks.
Have a happy and safe New Years Eve this evening, and tomorrow, I promise, no shorebirds.
