Hay,
here are 3 Gulls from 17th and 28th January 2012.

1. Photo: For me it was a 3cy Herring Gull but somebody means that the bird is "heavy cach-blooded". What are your thougths?

2.-5. Photo: 3cy Caspian Gull

6. Photo: Paler 3 cy Herring Gull?

Hope you can help me.

hi armin,

birds 1 and 3 are pure 3cy argentatus.
as for the 3cy cach - to me it looks ok but there might be people who would argue it has a too strong window and slightly pale iris to be a pure one. all within variation of cachinanns though.

cheers
