Lesser Black-backed Gull 3CY, July 18 2013, Katwijk, the Netherlands.
Unringed, hence no provenance about origin, but in all respects nice match to local "Dutch intergrade" Lesser Black-backed Gull.
Bird in complete moult: P2/P4 (P3 still present in left wing). Two secondaries replaced, probably from moult on winter grounds, and also all tail-feathers replaced on winter grounds for 3rd gen, now white with just single small black spots.
