OK, here we go again - another "Thayer's Gull" and, once again, not a classic bird. I haven't got long to go in to detail right now but 1) the tertials look far too pale, 2) the primaries look too pale and 3) the scapulars don't have that typical solidly dark-centred pattern of thayeri.
Sure, it's a great-looking bird and a very nice find but I'll pipe up with the same point I proposed when that less-than-typical bird was in Galway last winter - where do we draw the line with kumlieni, and why are we getting so many atypical (at least in a vagrant context) juvenile "Thayer's Gulls" turning up?
It must surely be worth considering the possibility that Herrings and Icelands also do actually hybridize, contrary to popular belief.
Totally agree Josh. We are getting bird after bird that falls into this category in terms of these ''Thayer's Gull lookalikes''. I was never a big fan of the Oxfordshire so-called Thayer's and nor did I support the idenification of a recent Sligo bird. Some of these birds seem to have Smithsonianus influence, even this latest one near Oban
Lee What features of Smith do you think these/this bird show?
Was amazed to see people calling that one of the 'best candidates' that there has been; surely the other Galway bird (Ross Beach) looked infinitely better!
I'll start the ball rolling with the Denmark bird.
And the Norwegian bird.
