Finally, Caspian falls

So far, my only 'in-the-flesh' view of the Caspian Gull in Bettws. Arrived just in time to see all the gulls take to the air and drift off. I thought the underwing looked too dark (not helped by overhead conditions [rain, dull as dishwater] and under-exposure) and the tail a bit too michahellis-like but LGs, much better, photographs of the bird on the deck appear to show a Gibbins, et al. (2010; 2011) proof Caspian. Phew! Finally, a glaring hole on the Gwent list plugged. Well played SP.
