Many interesting revelations to come in the crossbill world very soon so keep posted but meantime a bit of fun ! If Menzie can put up blurry, dodgy pics of his Spanny birds and ask "how many species" then so can I with Crossbills. To make it easier though rather than photos of crossers, which most people seem to get wrong or concede "they just don't know", I have this sonogram instead:
It was recorded on 16th April 2009 in upper Deeside, native Scots Pine habitat (using ME67 and Sony HiMD). So, how many crossbills and of what crossbill species, and more importantly how many call types ? I bet Menzie gets them all correct, he always does !
Posts are moderated, but I will put the non Chinese spam ones on honest !
Spread the crossbill love.
