Lesser Black-backed Gull graellsii LLLJ 1CY, October 04 2013, Portimao, Portugal. Picture: Carl Baggott.
1CY LBBG, ringed on July 07 2013 at Havergate Island, Orford, Suffolk, England by Mike Marsh.
Most upper scapulars replaced, lower scaps still juvenile. Coverts and tertials juvenile, but few inner coverts seem to be missing and this may be the first step in post-juvenile covert moult.
