14. Behavior of bird / circumstances of observation (flying, feeding, resting; include and stress habits used in identification; relate events surrounding observation): First observed resting amid a large group of roosting gulls, terns, pelicans, etc. After several minutes, the Glaucous flew over the jetty and upstream along the river as gulls congregated around a returning fishing boat. We then drove to the ferry, and refound the bird as it rested on and flew over the river downstream from us.

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.

17. Similar species (include how they were eliminated by your observation): Larger than the other gulls present (including Herring), and considerably paler. Most likely confusion species was a bleached Herring Gull, but given the bill pattern and lack of any dark markings on the wingtips, Glaucous seems the best fit.
