American Herring Gull (smithsonianus) 2nd cycle (2CY) M99 November 23 2013, Salisbury state beach, Massachusetts. Picture: Gracie5964.

See website: The Gulls Of Appledore. M99 was banded as a chick in July 2012, at Appledore Island.

Note bicoloured bill and pale iris at this age. Scapulars are a mix of brown and grey feathers. At the end of the complete moult (pre-basic moult in summer) this bird had a partial autumn moult which included the upper tertials, inner GC, central MC and a few LLC. These fresh feathers are grayish, more adult-like.
