Photo 3: LBBG 3cy, October 13 2001, Westkapelle, the Netherlands.
An individual, pretty hard to age with certainty. Some features apply to 3cy, like the dark centres of the fresh tertials and the bill (with a pinkish yellow base and a clear black bill-band. On the other hand, the tips of the fresh primaries (p8 full-grown) appear pretty large and could well apply to 4th generation feathers. Another adult feature is the all white tail.
