More Scottish Crossbill nonsense courtesy of bad PR can be viewed on THIS Birdforum thread.
And, just to see how hard it can be to find Scottish Crossbills these days see THIS Blog entry - a two man quest to find Scotbill in July 2007. The Scotbills were apparently so elusive that what they actually saw were in my opinion 'Parrot' Crossbills ! ( Sorry Rainer but reckon you might have to 'untick' that one ! ). To go to all that bother it might have been an idea to get a sound recording or two ? Scottish is much more confusable with Common - the birds in those photo's look bugger all like Common Crossbills.
For those who want to see a real Scottish Crossbill, here is one I prepared earlier, photographed near to its nest in March 2006 and emitting excitement call C:
