After about 2 minutes of perching on the branch and staring intently at me, it decided I was not of concern. It turned around, went back up the driftwood and disappeared behind it again. I never saw it again. It was the closest I've ever been to a green heron. For awhile I was a bit worried it was going to come and perch on my foot or something.
Green Heron (Butorides virescens)
