I spent a short while at Shawell at lunchtime today and amongst several thousand gulls was a nice second-winter Caspian Gull. As normal the falconer was there so the gulls were quite distant. Taking photos of gulls at this range with a strong breeze blowing is quite a mission, but I was able to get a few record shots.
The 70 x magnification, or power as the Americans seem to say, of my scope makes it possible for me to read colour-rings at distances of up to 400 metres if the codes are clear. One of my old (less of the old) favourites was there today - third calendar year Lesser Black-backed Gull C+F. I have now seen C+F on 14 separate occasions. C+F is almost in adult plumage now, which is quite a transformation from what he looked like back in January - see HERE
