Lesser Golden Plover at Buckenham?

Two readers of the blog (Derek & Edward) have been kind enough to suggest that one member of the Golden Plover flock I photographed yesterday is / could be a Lesser. I attach a couple more photos for those among you who know about such things to look at!
(I have seen several of each, but am far, far from being an expert!)
The bird in question is the one on the left in pic 1.
