Green Heron Near a Flooded Tuolumne River

It's been a hectic time and I haven't been back to the Tuolumne River in a week. It is still an artificial flood as the operators upstream at Don Pedro Dam are keeping flows very high to build flood storage capacity. The river has been high for two weeks now, and the entire floodplain is under water this week. I imagine a great many animals have been flooded out of their homes. I was wandering near the water treatment plant when I realized there was a large bird to my left, away from the river. I realized it was a Green Heron (Butorides virescens) standing very still, so much so that all six pictures I took are identical!
