never seen such an extreme assymetry plus the first (for me) documented thayeri pattern in a non-adult cach. quite sure its right wing has been seriously damaged and primaries have been replaced. p9 is missing. but even p6-p8 seem to have been replaced: they have large apical spots now and look much fresher than those in left wing! interesting bird - shows that such ind. could survive their damage. or was the loss of 3rd gen. outer primaries the result of internal (hormonal/metabolical) problems? but only in one wing - unlikely?
