Hybrid Herring x LBBG? Edinburgh

I have seen three different birds at Seafield in Edinburgh recently that may be hybrid Herring x LBBG. Yellow-legged Gull is a rare description species in Scotland and I do not think that any of these birds are genuine YLG, but I have wondered whether any of them might have YLG parentage... Obviousl...

Ring-billed Gull uneven tail growth

I photographed this individual Ring-billed Gull at Nimmo's Pier in Galway, Ireland, in December 2010 and again in January of 2012. I gather that it is one of the regular birds at the site. It has a small number of recognisable features in the various photographs that I took from the two years (e.g. ...

Re: white winged gulls

Any comments on this 1CY Iceland Gull that I found today in Edinburgh, Scotland? Obviously it is a dark individual and shows some Kumlien's characteristics. My assumption is that it is a dark glaucoides rather than kumlieni ... but that is based on an expectation that kumlieni should show distinctly...

Here is a link to the most darkly hooded Common Gull that I can find on the web. A little darker than the Ijmuiden bird posted.

Re: Can this be argenteus?

Thanks for the info and pics. The thayeri -type bird looks very similar to the mintgreen NH picture. I had another close look at my original shots and the mirror on P9 does extend across to the outer web, though there is a complete black border on the right and incomplete border on the left wing. Ce...

Re: Can this be argenteus?

Have started looking for thayeri type birds in Edinburgh again now that most of the wintering argentatus should be away. Obviously I'd have to find some breeders with this pattern to know whether these intergrades are part of the local population in South East Scotland. Nevertheless, here are a coup...

Re: Number of white primaries in Black-headed Gull

Thanks for the feedback, looks like it is an uncommon variant - rather than a diagnostic feature of some sort. Surprisingly the difference was visible in the field with the bird with 5 white primaries forming a fractionally larger wedge - sort of like an inverted sabine's gull. Nice resource little-...

Number of white primaries in Black-headed Gull

I photographed a 2CY Black-headed Gull yesterday in Stranraer, Scotland, with 5 white outermost primaries rather than 4. This may be perfectly normal variation, but reading Olsen indicates that this is a characteristic of sibiricus , though it is not really commented upon just mentioned in the descr...
