Lesser Black-backed Gull (graellsii & intermedius)

(last update: May 17 2015)

LBBG 1cy E37 E July 23 2004, Dintelhaven, the Netherlands.

E37 from Markweg location. Early July, some inner coverts were missing in the right wing. Those feathers are now growing, while the rest is still completely juvenile. Note that some lower upper scapulars are missing. This is often a first sign for the post-juvenile moult.
