Tidal flats and shell ridges that remain above high tide. Standing among several hundred gulls, pelicans, herons, terns, etc.

14. Behavior of bird / circumstances of observation (flying, feeding, resting; include and stress habits used in identification; relate events surrounding observation):

Standing and walking on the flats looking for food and resting. It did not flush when most of the other birds did. Possibly because of worn flight feathers.

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): Bright white body feathers including all white primaries with no black or brown. The body looked a little more smudged with wear than the birds seen earlier in the winter at the same location. Bill pink with black tip. Legs pink. Larger than the Laughing and Ring-billed Gull near by. About the size of the Herring Gulls.

I feel this is probably one of the birds seen at this location over the previous months that is starting to show more feather ware.
