13th - The wind was a strong north-westerly today but the sun still shone as we made our way to the beach at Piemanson. As expected the sea was fairly agitated and seabirds were everywhere. A number of Common, Sandwich and Little Terns were feeding just off the beach within easy binocular viewing distance. After about 20 minutes I spotted, just below the horizon, a number of European Storm-petrels flying west. Their characteristic bouncy, almost swallow-like, flight made identification relatively easy and everyone eventually got on the birds. Luckily for us a fishing boat then appeared and within 20 minutes or so birds were being attracted from over a large area. At first Yellow-legged Gulls were the only prize but soon a number of Balearic Shearwaters were shearing and banking in the boat's wake and a juvenile Gannet was also curious. Several Gull- billed Terns joined the throng behind the boat as it headed west and out of sight. Peter then spotted 2 adult Caspian Terns as they flew in off the sea and a minute later they were followed by 4 juveniles. An excellent sighting. We decided to explore the scrub behind the beach next but it was quiet apart from a pair of Tawny Pipits, a pair of Reed Buntings and several Yellow Wagtails ssp thunbergi. As we walked back to the van a pair of Gadwall and a female Eider flew over. Just behind the beach we stopped to admire a flock of 30 or so Slender-billed Gulls showing a nice contrast with juvenile Black-headed Gulls alongside. Making our way back into the Camargue we stopped at the Baisse de 500 francs in the hope of an Audouins Gull but none were present although we did spot a pair of feeding Avocets on a small pool. Our next stop was at the Etang de Tour du Valat where we had very good views of a Crested Lark and a brief look at a Short-toed Lark which perched on top of the garrigue. Yellow Wagtails were everywhere and were all of the ssp. thunbergi. Further north we stopped by La Capelliere to admire the nesting Black-winged Stilts and heard a singing Whitethroat, spotted a Fan-tailed Warbler, 2 Melodious Warblers and a Yellowhammer and then heard a Cuckoo calling. The White Storks and young on the nest by the reserve entrance gave everyone good photographic opportunities.
