Wryneck at Corton old sewage works

I arrived early today on Monday 29th August, Along the southern ridge of the Corton old sewage works compound the excellent Wryneck was seen briefly by ragwort and then in the south- eat corner by a gap between 2 clumps of grass. In the north -east corner a Whinchat flew up the bramble bush and corner fence briefly. walking around the other side I saw the Wryneck fly over to the south section, I saw it out in full view and it flew up to a broken alexander stem and it showed here for all of 3 minutes. Before James B walked up. At Bakers Score, I saw 2 Gannets flying south over the sea. A look around the North Denes revealed a male Blackcap feeding on elders on an elder bush behind the Oval (south side), a male Whitethroat by the first shelter belt. In the garden, nice to see 2 Small Tortoiseshells on the Buddlea one of which frequently alighted on some clothes on the washing line but was very wary and was off on the 2 occasions I tried to gert a pic of it! This evening I watched 8 adult Common terns feeding c15 young on the groins several flying close by and 3 immature Kittiwakes flew south but still no Sandwich Tern!
