The number and type of herons at the Dhahran Waste Water Lake have been building up the last few weeks. New species seen include a juvenile Black-crowned Night Heron and three Purple Herons, the first ones for a few months. Great Egrets have increased to almost double figures and twelve Grey Heron was the high count. A dark phase Western Reef Heron was an unusual sighting with Little Egrets less unusual. Squacco Heron numbers are also steadily on the increase again almost reaching double figures.
