Bird Picture of the Week / Ukens Fuglebilde

This weeks bird picture has a questionmark behind it. Maybe someone can help me?

In the middle of what seems to be a rather poor year for most birds, the terns are busy bringing in food to feed their newborn chicks. This bird, although resembling a first-year tern in the autumn, however, is probably a second-year Arctic Tern (Sterna paradisaea), not a too common sight here in the north as most 2nd year birds stay in the south. Maybe also 3rd year birds can look like this, even though I thought they resembled the adults by that time? Or is it even a Common Tern (Sterna hirundo) at its 2nd year?

Around 100 people have viewed the picture on the national bird report system, where I reported it as a 2K Arctic Tern with a questionmark, but no one has commented on species or age. Any tern specialits out there?

The picture is taken on the 21 June in Tromsø, Norway, me being a bit behind the schedule on the bird picture of the week..
