Amongst the gulls are some tricky individuals that don't quite conform to the rules. The first-winters can be very difficult to separate from Lesser Black-backed Gulls. Some of these are not typical of the nominate Larus michahellis michahellis and a few may well be L.m lusitanius, or be closely related.
For anyone with an interest in these gulls I have put together a gallery of images.
