Thought this might be of note to those currently interested in wing barred crossbills in the northern isles just now. Many thanks to Stuart Reeves for passing these on to me last year ( or year before ? ) -
I also recall reading something about the two-barreds from last years irruption in either Birding World or British Birds earlier this year or last year.
Hope this helps - if anyone could get me some recordings of any crossbills from up there that would be fantastic !
