LBBG London GT 75716, June 02 2003, Papegaaienbek, Maasvlakte, the Netherlands. 

This presumed female has a red orbital ring and a clear yellow iris without speckling. It has no black on the bill and the red gonydeal spot extends on the upper mandible. It may be a female, judged on jizz (code V0). P10 has a medium sized mirror and the complete moult hasn't started yet: P1 is still present by June 02 2003. Compared to local LBBG from the colony, it appeared more slaty grey (slightly paler than Dutch birds).
