[QUOTE="SteveMM, post: 3521830, member: 130392"] Thanks for the links, JanJ. Just to clarify your use of the word 'these': Photo #4 is of a typical (for me), hence known, [I]mongolicus[/I] and shows the most common wingtip pattern I see here. Photos #1-3 show a different individual to #4, with a wingtip pattern that looks 'atypical' (to me). I guess the bill of the individual in #1-3 may be on the short side, and the white trailing edge looks broad. There seems to be complete overlap in wing pattern, then, with 'eastern' [I]cachinnans [/I](or at least what I can find described for 'eastern' [I]cachinnans[/I]), especially if the grey on the outermost primaries can cover so much of the inner webs! I'm never gonna find one here! [/QUOTE]
