Whilst birding the Dhahran Waste Water Lake over the last couple of weeks I have been seeing good number of Black-crowned Night Heron. They feed along the waters edge and are almost always on the far side of the lake, but occasionally fly around and give some opportunities to photograph them. There are about equal numbers of juveniles and adults and they often also associate with the local Squacco Herons. A single Great Egret is also always present along with up to ten Grey Herons. The Purple Herons that I was seeing in the summer, appear to have moved off though.
