We ringed this bird last week in Poreč, Croatia.

we started new seasonhttp://cro-ringing.blogspot.com/ so you can expect new mistery gulls:)

Hi Luka, the 1w does look as a normal michahellis in my opininion. Pattern of the new scapulars and the inner primaries looks good. Either does the tail, cf: http://www.pbase.com/albertdejong/image/139144925
