CASPIAN GULL in the Škocjanski zatok NR

Škocjanski zatok NR: I got the confirmation of the gull photographed yesterday (see previous post below). It was indeed a 1st winter CASPIAN GULL as I originally thought. Well, not right an everyday sight here, so a bit of a rarity, but still annual on our coast.
The head shape is distinctive, with the slender bill and small black eye. The very white head and underparts are also quite typical of the species - and the brownish "boa" around the neck is visible too. The legs have a quite long tibia, another good structural character. The overall plumage consists of three colours: white head and underparts, brown wings and greyish back. On the scapulars, the black anchor-shaped markings are also present and the tertials are brown with a broad white tip.
