15th - Only a brief visit to Mas d'Agon today, in the evening. On the approach road a couple of fly-over Squacco Herons were a nice surprise as they were my first of the year. The water level was still high in the lagoons, in effect limiting wader numbers. The big news was the return of the Collared Pratincoles. Around 30 adult birds were hawking over the lagoons on both sides of the road, providing spectacular viewing. Like a cross between a tern and a larger swift they certainly exploit their aerobatic skills to the full. A wonderful sight. I also noted a single Whiskered Tern in their midst which seemed less inclined to show off its flying skills. Waders were limited to 27 Black- winged Stilts feeding in an adjacent flooded field. The upside of the high water level was the number of ducks present which included a single male Garganey, 10 Red-crested Pochard and several Mallard, Shoveler and Shelduck. A single Purple Heron in the reedbed joined the resident Grey Herons, Little Egrets and Great Egrets feeding along the water's edge.
