A real rarity

You could tell it was a real rarity cos it turned up late, was watched in the gathering gloom and buggered off in short time - Semi-palmated Sandpiper on my Gwent year-list. The following horrendous pic does little to support the identification, but somewhere in there is a small billed, stint-sized wader lacking rufous tones in the upperparts. One ever-so-slightly interesting thing was that the mantle appeared darker when the bird was roosting, as opposed to when it was running around, presumably it was slightly fluffed up causing the dark centres to become more obvious but who knows.
