Thanks, SØREN, for an excellent photo of 3 vivid Knots in different flight 'mo(ve)ments'! I commented S. Skov's photo of 21st May 2006 of flying Knots, regarding a distinct dark patches appearing on the hand coverts of some of the birds, but not all of them. The right Knot on Your photo demonstrates that the SAME individual can display a dark patch on one wing, and None on the other one. So, apparently it's solely a matter of light/angle if a KNOT displays a black wing patch in spring - or NOT... Thanks ............. Yours C.
