It's back to Shawell now, but the memory of Scottish harbours full of 'white-wingers' is still fresh in my mind (not quite full, but it sounds good). I expected to find at least one 'white-winger' at Shawell but no such luck. I've had to be satisfied with encounters in the murky world of Caspian Gulls, plus a small influx of Yellow-legged Gulls. At least ten different Yellow-legged Gulls have been present this week.
The Caspian Gull below shows a good set of features, Long sickly flesh coloured legs; long parallel sided dingy yellow bill (dark marks on bill suggest immaturity); dark forward set eyes; small headed; long winged and the pattern of black and white on the underside of the longest primary feather (P10) is typical of a sub-adult Caspian Gull. The black subterminal mark on the bill and the upper wing pattern appeared slightly immature, so it is probably a 5th calendar year bird.
The shape of gulls can alter in a split second. One minute this Caspian Gull looked elegant and small headed and the next it could look hunched and larger headed.
As well as the one above, I saw a first and second-winter plus a hybrid Caspian x Herring Gull. The first-winter was a female and really dainty.
