Another yellow-legged Herring Gull

A short visit to the lake at Christianshavn produced a good number of gulls - mostly Herring and Black-headed but also some Common and Great Black-backed Gulls. A few were colour-ringed: one Herring had a blue ring "V457"; another Herring was carrying a yellow ring "VN47"; a Common Gull sported a red ring "C03" and four Black-headed Gulls had white rings "UHX", "291", "ULL" and "VYW". I believe that all of these have been ringed in the Copenhagen area but I will report them and see what comes back.. they may have been to some interesting places in between...

In the middle of the lake was another yellow-legged Herring Gull (see photo below). I am not sure where these yellow-legged Herrings come from but after seeing none for two years, I have now seen two in two days! This is definitely a different bird to yesterday's - note lack of dark mark on the upper mandible.
