The Trondheim mystery Gull
This dark-eyed large gull has triggered off many interesting thoughts on the birds identification and origin. The general American point of view is California Gull, while others believe it is a kind of Caspian Gull or a hybrid involving Caspian.

In addition to having the same strange jizz as earlier, some characters are still slightly puzzling for this probable 6th. winter bird: The primary coverts on both wings have extensive blacks pigments. Dark iris. P4 does show a distinct subterminal black spot on the outer web. The orbital ring is red, and it is completely lacking head-markings. Four pictures are uploaded here.

The debated mystery gull from last winter returned at the same site today.
Several people from both sides of the Atlantic thought it could be a California Gull ssp.
albertaensis. Some features, such as the wing proportions (see flightshots from February)
probably exclude California Gull alone, but the discussion still goes on... Have a look at four new pictures here.
