24th - Today a visit to the Crau in the morning and Mas d'Agon in the evening. I visited the main Crau area today rather than le Vergieres and within a couple of minutes I had seen a female, then male, Montagu's Harrier hunting. I spotted 3 Black Kites soaring on thermals and a female Marsh Harrier in the distance. A number of Kestrels and a single Lesser Kestrel were perched on the stone piles as I drove further into the Crau. I decided to walk for a while and immediately disturbed a Stone-Curlew which flew a short distance and was relocated on the ground. Several Crested Larks were still singing and a Red-legged Partridge called as it flew off. I spotted a Southern Grey Shrike as it perched atop a bush then flew to another nearby. Both Tawny Pipits and Calandra Larks were then seen in flight and, finally, on the ground. Having made up my mind that nothing more was likely from this area I decided to take a short cut back to the car across the coussous. It was an inspired decision as I disturbed a Pin-tailed Sandgrouse that had been sitting anonymously within 50 metres of where I was standing ! It flew a short distance and I had excellent flight views but on approaching it on the ground the bird flew off - still, a real privilege to see such a rare bird up close. As I left the Crau I spotted a Whinchat, singing Corn Bunting and Roller on a telephone wire. A brief stop at the Entressen rubbish dump produced only 30 Black Kites, 300 Yellow-legged Gulls and a single White Stork. The evening visit to Mas d'Agon produced the usual suspects - Night Heron (adult + juvenile), Little Egret, Great Egret, Squacco Heron, Grey Heron, Purple Heron (4) and 25 juvenile Flamingoes over. Terns were again numerous with the resident Whiskered (50) joined by Common, Gull-billed and a couple of Black. But it was the sight of an adult Bittern flying close by that made the visit worthwhile - not an easy bird to see anywhere ! I also spotted a single Savi's Warbler in the reeds and a Marsh Warbler along the canal by the farm. At La Chassagne, on the drive back, I spotted a Hobby that had landed on the ground only to be attacked by a male Kestrel ! The Hobby eventually flew off !
