Hello,
a local birder found this gull an a pond near Schweinfurt/Germany today and asked me for my opinion:
I am fairly confident that it is a 2nd winter caspian gull.
Although there are some points that puzzle me:
-> there is apparently no streaking on head or neck
-> the mantle shows too light a tone of grey
-> in the flight shot some of the inner primaries seem to be already 3rd generation feathers
But there is a white mirror on P10...
Well, I stand to be corrected...
