Lesser Black-backed Gull 2cy, June 24 2013, Noordwijk, the Netherlands.
Bird without ring, hence no provenance on origin. However, typical intermedius-like moult: extensive moult on winter grounds, including most inner wing-coverts, tertials and almost all rectrices.
Complete moult just started in primaries: P1/P4 (P2 already at 2/3 of final length), and indicated as well by missing outer LLC and MC.
