Slaty-backed Gull (schistisagus) 1st cycle (2CY), January 17 2012, Choshi, Japan. Picture: Michiaki Ujihara.

Please visit Japanese Gull site for many more pictures!

Still completely juvenile plumage (bird from northern latitudes?). A fresh and dark individual recalling American Herring Gull. But note the short-winged, stubby overall structure and pale fringes to the primary tips.
