This bird is NOT captive.
This is probably the closest I'll ever get to one of these herons. I was fishing at a gravel pit with my grandpa in a boat, and I noticed a green heron sitting on top of the beaver dam. We slowly made our way over to it, just seeing how close we could get. We got within 15 ft of it, when I asked if I could get my camera out of the truck. We went back to shore and got my camera. We slowly made our way over to the dam to find the heron in the same spot. We just kept creeping in closer with the help of a trolling motor. It eventually got scared when we were about nine feet from it. He didn't seem to mind and was still fishing when I was taking these pictures. There is no way I would ever get this close on land. I think he didn't mind because we were at his same height level in the boat and, with the help of a trolling motor, were silent. Vermillion County, IN
