Photo 1: sub-adult LBBG, October 13 2001 Westkapelle, the Netherlands. 

Advanced moult in the primaries with p10 almost full-grown. This is a typical 4cy with prominent white tips on the primaries, a clear white mirror on p10 but otherwise an immature bill an obvious black bill-band and a pinkish base. Somewhat resembling a 3cy LBBG, depicted in the 3cy October section.
