14. Behavior of bird / circumstances of observation (flying, feeding, resting; include and stress habits used in identification; relate events surrounding observation):Bird was sitting with a large gull and tern flock. Most of the birds in the flock were small, especially Forsterís Terns.The bird was near Laughing Gulls but not associating with them. It was the bird perched the highest and farthest from the waterís edge, standing facing the water from the bare strip of sand above the recent tidelines.

Short-legged, stocky medium-sized gull with blocky head, pale gray upperparts, plain black wingtips, black eye and yellow bill.

 

Silver-gray above, with all feathers except for mantle appearing very worn. Wings worn, with dusky markings on greater primary coverts, either due to wear or perhaps remnants of a subadult plumage. outer primaries plain dark black, with dark edge to entire visible outer web of outermost primary (p10), similar but much shorter mark on next innermost primary (p9). Primaries skeletal, white areas of primaries especially worn. Dusky tips to badly worn inner primaries (like associated dusky coverts) probably a sign of subadult plumage. Flight feathers slightly paler than upperwing coverts. Thin white trailing edge on secondaries, almost obscured by wear.

 

Head white, with a small dark smudge about the size of the eye above and adjacent to the rear half of eye, and a larger, slightly duskier ear spot. Slight dusky streaking connecting the eye smudge to the top of the ear spot, with duskier streaking connect both ear spots forming a weak hind-collar. Neck white. Eye dark brown, bill completely unmarked medium yellow. Some duskiness at base of bill, probably stain.

 

Rump and tail white.

 

Underparts white.

 

Legs dark, with dusky pink or purple hint. Legs not black.
