Photo 4: LBBG adult, August 18 2001, Missouriweg Maasvlakte, the Netherlands. 

Adult from the colony; p5 missing, p6 old. The upper two tertials are missing. In the wing-coverts, the inner two greater coverts are shed and probably the inner two median coverts as well. A few central lesser coverts are missing too. The scapular region is a mix of old brown hued feathers with strong wear in the fringes, combined with fresh plain grey feathers. This bird probably started the head moult as well as the nape appears fluffy and feathers are missing here.
