Yesterday there were plenty of gulls to look through at Passage House. After about 10 minutes of scanning I came across a gull that immediately looked a lot different to the juvenile Herring Gulls which where in good numbers...
It was long legged, long winged, had a fairly large angular beak, a dark eye mask, and dark bases to the greater coverts. It was also noticeably larger in overall size than the nearby Herrings. These features all pointed towards it being a juvenile
Yellow-legged Gull, however there were two things that were bugging me. The tertials had more notching than you'd expect, and there seemed to be a bit too much spotting on the inner greater coverts. Also, the scapulars perhaps aren't as dark as they are on some birds. I got a few glimpses of the tail and the open wings but failed to get a good shot of them.
It eventually took off and gave me good views of the clean white rump and dark inner primaries, although again I couldn't get a good shot.
I would appreciate some more opinions on this bird. My own opinion (not that I'm a gull expert - far from it!) is that it is a Yellow-legged Gull. I just can't see it being a juvenile Herring Gull, but I suppose it's possible that it's a hybrid.
