Gull (NE Italy) (1 Viewer)

Hippolais

Between hundreds of YL and Black-headed Gulls in Chioggia (Italy), two days ago, there was only one different bird: this one! I can't understand the age (transition from juvenile to 1st or 2nd winter?) and the legs are probably a bit too thick for a Caspian, but the "face" seems typical...
In the last pic, my bird is on the right: the left one is a Yellow-legged Gull

Menotti Passarella, one of the best european gulls expert, said that this is certainly a Caspian Gull born in 2010!8-P

Everybody seems to agree that age is 2cy (born in 2010). Why do Mr. Passarella think this is rather Caspian than Yellow-legged?
 
Indeed. The short and heavy bill fits Yellow-legged Gull much better than Caspian.
In the absence of flight shots, I think no single good feature is visible to turn this into a Caspian Gull.

That's a shame, as up to now, he no doubt identified every gull he has ever seen correctly. ;)

Sorry Hippolais, but your expert has made a mistake with this one.

In your third photo, the bird in question has a broad, square head just like the other YLGs in the image. This is diagnostic. If you don't believe me, ask your expert to find a short necked, square and broad headed Caspian Gull photo from elsewhere in Europe.

Cheers,

Andy.
