Lesser Black-backed Gull (graellsii & intermedius)

(last update: May 17 2015)

LBBG 2cy, September 30 2001, Le Portel, NW France.

As commonly seen in 2cy LBBG, by September the scapulars show grey adult-like feathers randomly. The new median coverts are still growing, the inner 3 greater coverts are new as well. The lesser coverts are a mix of old abraded feathers and fresh greyish coverts. The upper 3 tertials were moulted recently.
