American Herring Gull (smithsonianus)

(last update: October 30, 2015)

Slaty-backed Gull (schistisagus) 1st cycle (1CY), September 16 2009, Hokkaido, Japan. Picture: Hannu Huhtinen.

Juvenile plumage. Much dark in tail and already overall 'washed-out' mud-brown impression, however, by September white fringes on scapulars still present.
