This bird, billed on the pagers as a probable Caspian Gull, has a rather short primary projection, a broader than normal tailband and patterning on the inner greater coverts. However, as far as I can see other features support Caspian Gull including:
Head and bill shape.
Bullet-hole eye, surrounded with some eye-shadow and white eye-lids.
Green bill with a black band and some red on the gonys.
Long, greyish-pink legs.
Small white mirror on second generation P10.
The apparent white tongue on the inner web of P10 (see 2nd picture) is probably an out-of-place tertial.
Very white underwings, outer primaries fairly translucent because of pale inner webs.
Restricted black on primaries, relative to michahellis.
I would not diagnose this bird as a hybrid or anything other than a female 3CY Caspian Gull. However, I have been wrong before and maybe there is just too much wrong with it to be sure of any identification.
Postscript: BirdingWorld magazine has this bird as a definite Caspian Gull (and a better picture!). So, on balance I include this under Caspian Gull.
