觀察細節

Found by AM. Well seen. Very familiar sp for me, though mainly from its normal wintering grounds. Still in post juv molt but axillaries grayish with thin white inner stripe when wing fully stretched ; cheek spot and post oc stripe. Small but long winged with slender bodied in flight and v small on ground vs EUGP. Jizz wrong for PAGP. Videos / foto to upload. Not showing much of a high survival phenotype being largely on its own or at edge of flock, quite noticeable by small slim size even in airborne flock when high and birds were all together.
