Message: <blockquote data-quote="Gordon" data-source="post: 3567455" data-attributes="member: 2003">I did a screen grab and adjusted the lighting in Elements.  Doing that it "appears" that the carpal is actually quite extensive. Also, the overall underwing pattern can be seen to appear like a HB (or a juvenile CB if one is so inclined).  I think, given the quality of the pics (no offence intended) the identification to species is open... not saying either view is right or wrong.It reminds me of a discussion recently when someone asked for an ID based on the call - 2 camps immediately opened up, both stating that it was "definitely" a Peregrine and the other Green Woodpecker.  Both camps were able to produce experts (ie, people with acknowledged experience of both species... members of raptor study groups, international film makers etc) but at the end of the discussion I don't think anybody changed their minds - despite sonograms being presented for comparison.  At least no-one came back to acknowledge they were wrong despite the more objective evidence that was put forward.</blockquote>
