I am leading a bird tour on Sunday August 8th. The meet up is at Hackbridge Train Station at 0915 to 0930. The tour duration is 1.5 to 2 hours. Hopefully there should be some waders about like Greenshank (pic) and also plenty of other migrants. There is a good chance of Hobby, Green and Common Sandpipers, probably lots of warblers and maybe Whinchat, Wheatear and Cuckoo.
