Hybrid Gull at Cosmeston

As well as the Glauc, there was a hybrid HG type which Jake and Mike thought it was possibly a so-called Viking Gull - i.e. HG x Iceland. I didn't get a photo this morning [no camera] but it was still present late afternoon and I think this is the bird in the photos below. This has been around for some time and I had always taken it as a part leucistic HG. Freely admit I've never heard of a Viking Gull.

Viking Gull is actually a Glaucous x herring hybrid, however this bird was much smaller in stature than the 2CY Glaucous present there today. Although it appeared just bigger than Herring & LBB gulls present. The primaries shown in John's photos are in shade, in sunlight they were a lightish brown and in flight looked semi translucent. Both Mike & I saw something very similar in Scotland, which was being called 'Viking Gull' and that wasn't really any bigger than the herring gulls present. I'm sure there are gull-freaks out who can put us right.

I'd be inclined to say leucistic Herring as everything about it appears leucistic. I would expect Viking, Nelson's or any other hybrid to show normal blackish pigmentation to the bill. Yours 'moss-freak' ;-)

Thanks Mossy, looking again I think that is the case.

Agree, very probably a aberrant Herring Gull in my view.

This bird has been down there for a while. I'd put it down as a pale herring.
