LBBG 10cy UP8, Missouriweg - Maasvlakte, the Netherlands, April 29 2002.
An adult male ringed left orange UP8, ringed as pullus at the nest, July 10 1993. This bird is now in 10cy. Note the slight wear in the tips of the outer primaries and scapulars. In the scapulars the difference can be seen between new dark grey feathers and older worn grey feathers with a brown hue. Although this bird is in 10cy, the tertial tips are only ill-defined.
