Kumlien's / Iceland Gull 3cy / 4cy, January 24 2012, St John's, Newfoundland, Canada. Picture: Bruce Mactavish.

Pale iris, combined with immature bill. There is still a hint of sub-terminal patterning on the tertial tips. Only few feathers show the typical grey-tone of adult feathers. Bird extremely similar to 4cy glaucoides.
