LBBG 3cy W2XNJuly 11 2005, Neeltje Jans, the Netherlands (51.37N 03.41E). Picture Pim Wolf. W2XN is a classic 3cy graellsii and returned in NW Europe with old second generation tail, secondaries and primaries. The pre-breeding moult (in winter) included some wing-coverts and upper tertials. The complete moult has commenced: P1-3 are renewed (not visible in the picture). Visible P6-10 are old second generation primaries. Note the brown second generation tail feathers. Worn second generation secondaries are just visible beyond the tips of the central greater coverts. The bill looks already adult-like, with only a minor black marking on the upper mandible.
