Photo 2: LBBG sub-adult, November 20 2000, Westkapelle, the Netherlands.

A sub-adult with much black in the bill. The old outermost primary p10 is still present and lacks a white mirror and a white tip. These white parts may be worn away, but probably it's the retarded second generation feather, although a small white spot is visible at the primary from below. The outer primary coverts are brown centred, clearly immature. The upper-parts and tail are adult-like.
