P8 hidden behind P9. 26.02.2011

Same bird 2 years later. 30.03.2013

This bird is interesting. Note how the marking on both P9 and P5 evolves. P9 shows a window 2 years later, and P5 shows extensive black markings. Sadly not a bird with known age.

wintering Lesser Black-backed Gull in Oslo

This winter a LBBG has wintered in Oslo. It was first seen in December, and have been seen a couple of times since that. I saw it again yesterday, and that made me blog this.

All photos above taken by me, 9. feb, on Aker Brygge. Yesterday it looked more or less similar, so no moult going on. The bird is a 2.winter. I have many times questioned it age, but that is mainly because I am used to 2.summer intermedius/graellsii with a lot of new feathers on the back and moult in primaries. From what I find on the internet it is quite normal for a 2.winter L.fuscus. The bird seems to have changed almost all feathers (most obvious: primaries, tail, secondaries, coverts) one time, and changed them with second generation feathers. Subspecie-wise it is a intermedius/graellsii, mainly because of moult cycle.

Edit: Later ringed at Aker Brygge 26.01.2013

More michalike!

Well, took some really distant photos in Bjørvika yesterday. This bird showed up in a few of them last night. Looks kind of like a mich, but....

...it is really long distance. White window in P10 only, thin black marking on P5, a bit long tongue on P7...
