I swung by the gull roost, on the way to the grocery store, and unfortunately happened to have left my telephoto at the office, thus I have only these poor digiscopes, a process with which I have only the most basic experience and skill. This Slaty-backed Gull stood out immediately thanks to its strikingly white wing coverts, blueish-slate back, black tertials, and even at a distance, its "typical" SBGU facial pattern. The bill is messily black-and-flesh, with black tip and cutting edge but patchy flesh around the base. Iris, light brown shining lighter in direct sunlight. Facial patterns typical slaty marks including a heavily "mascaraed" eye, well-defined vertical brown streaks along the hind-neck, nape, and crown, and a very obvious "ear patch," noticeable even at a great distance. Legs, vividly pink, more so than WEGU. Mantle showing limited, gray-blue mantle feathers and isolated scapulars approaching near-black. Coverts ranging from tan to striking cream-white in good light. Tertials gorgeous near-black /deep brown with expansively broad, contrasty, frosted-white edges. Primaries brown-black, lacking any pale edges of regular GWGU hybrids. Open wing shows secondaries off-white graduating through tan inner primaries to dark brown outermost primaries. I left the bird at sunfall and low-tide with perhaps 200 tourists gathered to watch another postcard sunset over the granite coast.
