Photo 6: sub-adult LBBG, October 14 2001 Westkapelle, the Netherlands.

In general it appears to be in adult plumage, including a white mirror on p10 and a relatively low moult score. There is a mirror on both p9 and p10 and the tail is white. P6 full grown, p8-p10 old, and the outer primary coverts are brownish. This is combined with some lesser coverts which still are immature (with a brown centre) and the well-developed black bill-band.
