Hello, I would like some help with this wader, seen on my exercise walk this morning. It was in some local watercress beds, I saw it briefly in flight, I also saw something in the same bed last week, but only as it flew away. I'm suggesting green sandpiper, as in flight it looked very "black and white"- I have seen a similar bird in other watercress beds and the river Arle over the past few months, on one occassion very much looking like a large swift or house martin. Today this little chap was a fair distance away and I only had a pair of 8x25's with me, the overall look was a dark brown bird with greyish head and very white underparts. Greyish legs. The attached pictures do seem to show an eye stripe too. I would value your opinion. Location- Hampshire, Alresford, about 25 miles inland, lots of cress beds around though!
