When 4 became 2

On Sunday 3rd May, Rob H. had told me about the 4 BWS's at Carlton Marshes I went staright there (switching my heavy Canon lens for the much lighter Nikon one- too far to walk with it now!). As usual I was late to the party seeing Carl B, Paul & Jane F, Chris, M. Phil and even John H. as I walked up. My late ness meant I missed 2 of them as they had flown to an inaccessible part of Peto,s in. the north- west corner. 2 Black- winged Stilts remained and were busy walking around feeding by the waters edge. 2 Greenshank also seen stood at the edge together. As I walked around the river wall, the 2 Greenshank flew north but the Black- winged Stilts remained feeding the male had black smudges on his head and the female a pure white head. Whilst overhead, 8 Hobbies seen plus 2 Swift above them. With gavin, I checked the North Hide area, not much seen here. Walking back, we saw the 2 Stilts again, we were joined by Tony B. and we saw a fine summer plumaged Black- tailed Godwit along the closest edge of the water too. I saw a low flying Bittern fly right and then settle in the reeds. A close quartering male Marsh Harrier seen too. walking back we saw Douglas from Winterton but by the time the remaining pair had flown north.
