We found the second Yellow-legged Gull for Satakunta county with Jaakko Esama from Köyliö landfill (SW Finland) today. The same individual was seen in Uusikaupunki fishing harbour couple of days earlier. This represents only the 30th individual for Finland if accepted.
Below is a sound recording of its longcall - the first recording made in Finland as far as I know.
I'm very happy about this bird as it was new and 305th species to my self-found list, it was about the time to find YLG as probably all Finnish landfills are going to be changed as waste burning facilities during 2015.
