Tonight at Dorney Lake I could only see a single WHIMBREL (present for the 4th day) feeding in the grass behind the Reserve Pool viewed from the middle bridge. The second could easily be hidden but since arriving they have always been only a few feet apart. So perhaps it has finally departed.
The only other birds to note were 7 Egyptian Geese and a Oystercatcher feeding around the Seasonal Pool. Still all present at 20:20 (Kevin Duncan)
