LBBG 6cyEY17, May 13 2002, Dintelhaven, Maasvlakte, the Netherlands (51.59N,04.02E).

Ringed June 24 1997. Only in 6cy, this bird has a small rounded mirror on p10, situated relatively far from the primary tip. The outer primary tips are worn away and only a small white tip is visible. It seems this individual didn't develop large primary tips anyway.
