Photo 7: LBBG 3cy, June 17 2001, Missouriweg, Maasvlakte, the Netherlands. 

An individual with slightly advanced covert moult, but with very black primaries. The primaries are 2^nd generation, without tips and no mirror on p10, but there is a very small spot visible at the tip of p5. This individual much resembles the one in picture 8.
