14. Behavior of bird / circumstances of observation (flying, feeding, resting; include and stress habits used in identification; relate events surrounding observation): Very relaxed and not skittish. Standing on jetty preening at first, then flew into the marina channel to follow a boat in with other gulls. It was a little shy at first when food was thrown, but then became more aggressive. Finally, it flew up on a close by jetty and got into a “sleeping “ position…legs tucked under it’s body. Seemed quite relaxed and comfortable.

15. Description (include only what was actually seen, not what "should" have been seen; include if possible: total length/relative size compared to other familiar species, body bulk, shape, proportions, bill, eye, leg, and plumage characteristics. Stress features that separate it from similar species): By comparison with RBGUs that were present, it looked to be the same size or just a bit smaller. It’s bill was rather small and dark, but flesh colored near the base on upper and lower mandible. Eyes were dark. Plumage was white with very light beige spots…kind of mottled. It was much larger than the laughing gulls.

16. Voice: It’s voice was higher pitched than the laughing gulls that it was competing with for food.
