LBBG 1cy NLA 5.412.281September - October 2004 & July 2005Amsterdam, the Netherlands. Pictures Ruud Altenburg.

below: LBBG 2cy 5.412.281, July 05 2005, Amsterdam, the Netherlands.

Typical local 2cy LBBG in July.
The rear most scapulars are still second generation and very abraded (the fringes are completely worn away) and most other scapulars and mantle feathers are fresh third generation (but again second generation-like in their pattern).
The moult has started and the inner primaries P1-P5 are replaced, P7-P10 are still old juvenile. At the same time, the tail feathers are moulted as well and new feathers are still growing. Two secondaries have been replaced recently, but the location of these feathers suggest they are no part in the complete moult.

Ringed at the Sluizen, IJmuiden, 10-07-04. This bird has replaced a tertial, two greater and a median covert. Oddly enough, the scapulars still are completely juvenile.
