Photo 20: 2cy LBBG, July 14 2001, IJmuiden, the Netherlands. 

Only p1 and p2 are missing resulting in an extraordinary low moult score of only 2. Normally, in a group of 2cy LBBG the variation from the average score is large compared to other large gull species, but this score is exceptionally low. All the tertials are second generation. Only the outermost greater coverts are still juvenile, while the other wing coverts are all second generation, barred feathers. Note the brown tone in the fresh scapulars, where older scapulars have a distinct pale (white) - black pattern.
