Hi
Watching the news about the Concave in Rome, there was a “Large, dark backed, White-headed gull standing on top of the chimney where the smoke will appear. The gull was dark backed like Great Blacked Gull, leg color couldn’t be determined. In looking through Birds of Europe, 2nd edition the possibilities for black-backed gulls are few, Great Black-Blacked Gull and the Lesser Blacked-back Gull. It appears the gull would have to be accustomed to urban environment.
Anyone have any thoughts
Cheers,
