It is considered to be an Iceland Gull (Larus glaucoides) though this is not to say it is not a Kumlien's Gull. It has without doubt some faint pigmentation along the tip of the outer primaries. However, note that it is not abnormal for 2nd- and, especially, 3rd-cycle glaucoides to show a brown wash on the outer primaries. The plumage of these immature gulls often looks quite retarded, with still lots of brown in the wing. Note that the brown wash on outer primaries of such birds simply matches the brown wash on outer secondaries, as is often the case in other 3rd-cycle gulls (e.g. Herring Gull). It is just a trait of immature plumage.
