Black Crowned Night Heron
The area I frequent has a large drainage ditch, more like a stream actually, that runs along one side of the wetland. At some point a large tree had fallen over and landed across the water. I think this Heron had started living within the fallen tree because I would often see it disappear down into the branches.
A couple of weeks ago the city sent out some equipment to clear out the drainage ditch in anticipation of the summer rains and they removed that tree. For days afterward, when I would be out early in the morning, I would see this bird perched on a branch above where the tree had been, just sort of staring off into the distance.
