Most of the blue herons that we saw at Chincoteague were young birds, not yet fully matured and fully colored. But, we managed some great reference material. Again, as with that one 'show egret', we had the good fortune to find a heron that stayed pretty much in the same spot each day and let us catch it in all sorts of light and poses. I guess most of the birds are rather aclamated to the passing vehicles and walkers so they don't always fly off. Good for artists in need of descent reference material! At one point, I was hardly ten feet from one of the herons.
