Awoke to thick fog but at least it was virtually calm. Passerines remained in very short supply with just the Stonechat, a few Wheatears, a Willow Warbler and 5 Tree Sparrows around Norwick but there were a good number of grounded common migrant waders comprised mainly of Dunlin, Sanderling and Turnstome on the beaches and even at Lamba Ness where I flushed c.40 Snipe and saw 5 Knot walking around on the short turf. Brydon had heard an American Golden Plover a couple of times around Baltasound and then a third time just as I was making my way there. I joined him and Casey at the houb but there was no sign. We decided to walk the field to the north as it was playing host to a large flock of Golden Plover but it wasn't among them. Just as we were walking back towards the houb we heard the lovely clear drawn-out 'chew-weee' flight call from somewhere behind Skibhoul Stores that quickened our pace especially when it was followed by a second closer call that left us sure that it had landed on the houb... but just as we were approaching the road we saw all the Turnstone take flight, and whilst we never heard or saw the AGP, we had that sinking feeling... so it was no real surprise when Rob sent a message to say that it had just flown over his house at Ordaal. We headed in that direction but all too soon Rob saw and heard it flying back towards the houb, and despite our best efforts, we failed to relocate it.
