I was on my way out when I spotted another birder, Rob Daves, in the area. Figuring he was there for the same reason as I was, I decided I would point out where I had seen the heron. We both watched the heron for a while, I even tried to use my doubler to get a closer picture but with no light it just was not working. Then we got lucky and the bird flew near to where we were standing. We got a good close up view and a picture.
It was still a bit blurry because of the lack of light, but it is obviously a green heron. Probably an immature due to the abundance of white streaking in the throat and chest. I am not sure if this was the bird that was reported. The one that other birders had reported was supposed to be mixed in with a couple of black-crowned night herons but this one was alone. I may try to get back and check again when I have a bit more light.
