Can any larophiles comment on this particular gull, which I'm thinking might be a 2nd winter Caspian Gull. The picture was taken on 20th Feb.
It was Herring Gull sized but didn't look it, and the tail had a broad black terminal band with a white upper tail, with only very light flecking leaching up onto the white uppertail from the black band. The inner primaries were pale creating an obvious pale patch at rear of elbow. Black tertials, heavily fringed white. The head and neck was all white except for very light flecking on the lower nape and around the sides of the breast.
Legs were yellowish-flesh. Eye dark.
Not too many opportunites for studying gulls around here so any constructive comments would be most appreciated.
The angle of the bird in the pic shows the grey on the mantle to be slightly darker than in life. A few 1st-winter feathers can be seen admixed with a more adult grey feathering.
