Giving this up as a bad job, I got a call from Bob suggesting that I look behind me! Down below he and another were seemingly concentrating on something perched on a tree just above the path near the Pinkhill Hide, but on the east side facing the mown grassy area. From my position I could just make out what it was they were photographing - the tame male Kestrel that others have come across recently in the same general area.
So I made my way down there as fast as possible, and to my amazement the bird was still there when I arrived and set up my gear. Not only that it tolerated a remarkably close approach by 3 (soon to be 4) photographers. It didn't seem at all bothered by our presence and remained on its perch for a few minutes before having a leisurely stretch and then flying off, not to be seen again.
