update! Med Gull at Aker Brygge

Have looked up the photos from Kristoffer Bøhn in PS now, and have concluded that it is in fact the same as at Marienlyst. The bird has a metalring on it's left foot (Norwegian size...), and the bird looks exactly like the bird at Marienlyst. So why have the bird decided to move around?

Most likely this is not a new-developed movement for the Med. I think that the Med and Common Gulls from Marienlyst sleeps somewhere in the fjord every night. Most likely the Med Gull was on it's way to the feeding area at Marienlyst when Kristoffer saw the bird on the ice at Aker Brygge.This technique seems to be normal in the Urban small Gull population in Oslo. Large amounts of Common and some Black-headed Gulls flies out against the fjord in the evening every day.

Here is all the photos Kristoffer managed to take of the gull at Aker Brygge. (full resolution)
