Another visit by the group to monitor the passage of Sylvia warblers through the site. With recent catches at Stanwell I did not expect much to be present, but this site even on a poor day always seems to have plenty of new Sylvia Warblers present, and produces relative few re-traps, clearly indicating a constant movement through the site. Despite the large number of Sylvia Warblers going through, being on the west side of London it is not a good for birds such as chats or flycatchers with few Whinchat, Redstart, Spotted or Pied Flycatchers seen with any regularity. The start was slow, picking up about 8 and dropping off rapidly around 10, with a single Whinchat being the surprise of the day, with a total of 116 new birds and 24 retraps.
