There was no special bird activity today although there seem to be a few more Wood Pigeons around. I tried twice for some interesting gulls at the dump. When I first arrived all the gulls were flying high up having most likely just been spooked by a raptor and they did not return during the course of a half hour that I waited. I decamped to Østensjøvannet where I thought some of them may have gone but there were no gulls there either. When I returned to dump later though all the gulls had retuned (3-400) and were feeding within the buildings much more actively than I have previously noted. I had about half an hour to grill them before once again something spooked them and they all flew up high and just circled. I did not manage to find a Caspo or a white-winged gull but amongst the Herring Gulls there were as usual a few strange birds.
The Great Grey Shrike was again showing well in Maridalen but did not catch anything whilst I was watching which was my hope. When I saw the bird on 15th and when Rune C saw it yesterday it had a notciceable black line headin back from the bill on its left hand side. This was not visible on the 9th and today there was only a faint sign of it. What caused this black line? Is is possible there are two different birds?

|Leif the partially leucistic Herring Gull who received his ring on 7 Jan. This is the first report of him since then showing that even a very noticeable bird can avoid detection for long periods|
|a pale Herring Gull that may indicate influence of Glaucous Gull or maybe not....|
