American Herring Gull (smithsonianus) sub-adult, May 20 2013, Appledore Island, ME. Picture: Shailee Shah.

Please visit Shailee's Flick photos for more pictures.

Long pale tongue on P10, yet with broad full sub-terminal band. Pattern repated on P9. Black on P9 reaches primary coverts. 'Bayonet' pattern on P6, P7 and P8 (ill pattern). W-shape on P5 and spot on P4.

Small black spots on primary coverts probably indicate 4th / 5th cycle bird.
