Yep, saw it - compilation for that week for all time, and not one in UK

that's correct, but you didn't consider climate change 3

In theory yes, but - and one of the main reasons why so many long-distance migrant birds are declining - they are not well adapted to catch up with it :-C

During the time I have been birdwatching, I have become aware of a phenomena I am calling "observer bias" in which the birder, when he sees a bird of unknown species, or when he only gets a glimpse or a brief view, in his enthusiasm, becomes affected by undue leaning towards identifying it as a relatively rare or more sought-after bird, when in all likelihood the bird he actually saw, is very very much more likely to be a commonplace bird.
I have been guilty of this myself in the past, so am not belittling the observer here.

I would be inclined to agree with you there. I have also been guilty of this many times in the past and in hindsight, there is nearly always a more likely option.
