(4 images) LBBG 2cy J93T August 22 & 28 2003, IJmuiden, the Netherlands.

Primary moult well in line with local Dutch 2cy LBBG: P1-P8 fully grown (and P9 longer than P8). Secondaries and rectrices fully grown as well. The central tail-feather R1 third generation-like. Almost all scapulars grey.
In the left wing, tertials replaced to second generation-like feathers in the complete moult, in the left wing tt5 older, probably replaced in the post-juvenile moult. 
This bird followed an uncommon moult strategy as can be seen in the wing-coverts. Many of these wing-coverts were replaced early in the season, on the wintering grounds. In the lesser coverts and in the lower lesser coverts some feathers are missing.
