A major arrival of white-winged gulls occurred on 5 January. Over the course of this and the following day, 8 Glaucous and 7 Iceland Gulls were present at Fraserburgh and Peterhead (totals combining both sites). This post shows many of these birds - the images are not all great, but at least they record a reasonable selection of the individuals that were present.
Notice the ticks on the Glaucous above. Virtually all of the birds carried these passengers - in fact we used the number and distribution of ticks to help distinguish between some of the more similar individuals. I've seen these ticks on white wingers in previous years.

Same Glaucous as above

Some cracking birds there. I hope a few from this influx have the good grace to head down our way in the coming weeks!
You know I'm a bit of a pedant when it comes to invertebrates ;) and I'm wondering if the ticks aren't in fact feather lice? If the they are, then I think they can be quite mobile, which could have a bearing on comparing portraits.
And I though we were doing well with 5 Icelands in the bay! Cheers, Baz
Hi Baz. Sorry, yes, i should have said lice. Interesting what you say about their mobility. The comparisons were between birds only a few minutes and max of 2 hrs apart, and we used number and distribution of lice (i.e. we are not talking about comparisons of birds seen days/weeks apart). Sorry if my initial commentary was unclear about this. Over what timescales are they mobile...would be intersting to know, for future reference...
Next time I catch a louse-ridden bird I'll give a few a prod and let you know how fast they move! I suspect not very fast, so I'm sure over the periods you're talking about your technique will be pretty valid.
Hey Baz. I look forward to results from your lice prodding antics :)

Hello Chris,
Very nice pics of this unprecendented (?) influx of white-winged gulls. Even in The Netherlands, birds have arrived. Last weekend I saw three Iceland Gulls, two of them had dark markings on the outer primaries. General opinions, despite the terrible quality of the pictures, is that the dark second winter is a dark glaucoides, and the light bird is indeed a kumlieni. My question to you and everyone else with an opinion on these birds: what are your thoughts on "my" birds? Pics can be found on my website http://www.pbase.com/martijnbot/recent. Any comment would be highly appreciated! Cheers, Martijn Bot (Zuidhorn (The Netherlands)
