Ringed as pullus on 10 July 1996 at Maasvlakte, the Netherlands. EM30 has a red orbital ring, a clear white-yellow iris, without speckling. It has no black on the bill and the red gonydeal spot is confined to the lower mandible. It is probably a male, judged in direct comparison with its partner (code M1). P10 has a large mirror. The complete moult hasn't started yet: P1 is still present by June 02 2003.
