Today I had a colourringed which I saw two years, see http://colourringedgulls.blogspot.com/s ... 2F%20black (look at the date!). And the Mediterranean Gull from last week was also still present.

Well done Maarten,
The islands in N Germany hold interesting populations of both HG and LBBG, transitions to argentatus and intermedius.

Thanks Mars!
