Photo 7: sub-adult LBBG, July 6 2001, IJmuiden, the Netherlands.

Probably a local Dutch intergrade sub-adult LBBG. In the carpal edge (the outer lesser coverts) a group of old feathers is visible. Otherwise this individual is very adult-like, including bare part coloration, grey upper-parts and wing-coverts, white under-parts and a completely white tail. The primaries show delicate white tips (most worn away) and just a relatively small mirror on p10.
