Sunday 20 August. Shoreham Beach: Ringed Plover 15W, Redshank 1W, Swallow 2W. Adur (Town Quay and Airport) 19:20-20:20: Ringed Plover 41, Whimbrel 2, Turnstone 4, Dunlin 10, Redshank 21, Yellow-legged Gull 1 juvenile (I confused myself into thinking it was a Caspian, thanks to David Campbell for putting me right).

checking the roosting gulls from the east bank meant looking into the sun but on a quick scan this bird's contrasting white head and longish black bill caught my attention. I also convinced myself it had a pear-shaped head and the eye looked large due to shadowing

a wing stretch showed pale inner webs to the inner primaries which seemed to fit Caspian quite well and I thought ruled out Yellow-legged Gull

thumb-nail pale tertial tips seemed to fit
as did the long, thin looking legs in comparison to the Herring Gull beside it and I was becoming convinced of it being Caspian Gull although I wanted to see a pale underwing to be sure. If I'd paid more attention i might have noticed that the eye still looked rather more than a bullet hole and the bill rather more chunky than explained by foreshortening 
I  quickly walked around to the Old Toll Bridge. The bird was more distant but the angle was much better, for me to see a raised underwing and in relation to the light.

concentrating hard on a hoped for wing stretch I failed to notice the contrast between the barred inner (nearest the tail) greater coverts, a strong indicator for Yellow-legged Gull and a feature I'd rather overlooked
nor it looking rather large headed and rather dark mantled
eventually it did a vertical wing stretch, too quick for an image but showed a very pale underwing. Job done I thought, but no as Yellow-legged Gull's can be too. Most of the literature concentrates on telling Caspian from Herring, rather assuming that the differences from Yellow-legged are more straight forward. Some are but I often find Yellow-legged a joker of a bird and it's caught me out again. 
I left feeling quite happy that I'd seen a juvenile Caspian Gull and didn't look at my images critically enough when back home
