LBBG 3cy November 08 2001, Westkapelle, the Netherlands.
In general this sub-adult seems to be adult-like but some features advocate 3cy:
- The pinkish basal half of the bill;
- The upper three tertials have been replaced recently but the white tips are small and almost confined to the inner-web;
- The outer primary coverts have a brownish-whitish tip and have a brown-hued grey centre;
- The tips of the outer primaries are relatively small.
