Marienlyst last weekend

Took a trip to Marienlyst and rest of Oslo with John Maritn Mjelde last weekend. Main point was something between ringing and reading colorrings. It ended up with no ringing, but some colorrings where read. A new Common Gull has arrived from Stavanger and was read at St. Hanshaugen, never seen outside of Breiavatnet in Stavanger. It was ringed in 2001, but got colorring firstly in February 2011. Most likely a stable Oslo area bird, since it only has been seen in Stavanger during the winter.

At Marienlyst we got some small gulls after 2 attempts. The Med Gull was still in the flock. The dark one that Simon had was seen briefly, and some underwing shoots where made. It disappeared and didn't return for bread.

A little to close actually

Also a Common Gull with Swedish ring metalring was present. I manage to read all the numbers by photos. Have made a map in Google Maps:

Today a Glaucous Gull was seen at Huk. Wonder if this is the colorringed one, or if it is someone new?
