Went back to see if I could see any little one's in the Blue Heron's nest and couldn't really see anything at all at the nest. And then this guy flew up there and started preening. Sort of surprised that they will get as close to the others nest as they do. By the way, after looking at a couple of shots of the nest, the Blue Heron was sitting on the nest. So guess there must at least be some eggs.
