I have never seen a (small) mirror on both P8 in a Herring gull.
I haven't found an example on the web.
Has anyone seen this before or is this really rare?

kind regards

I have only ever seen this in Iceland, where I suspect it is a sign of Glaucous Gull influence.
Was Chris' photo taken in the north of Scotland in winter?

Today this bird was present at my local patch (Houten, Utrecht, the Netherlands). All white p10, small marking on p9 and a mirror on p8. Not a very common primary pattern to me.
