Fog rolling in as I arrived, mild initially but developing gusty west wind. Did a loop around the lagoon but spent most of the time surveying the eastern third (confining my counts to this area), at least half of the time in the company of MOB watching the Ruff (a life bird for me - thanks Aaron!).

  8. Number observed: 1

    Details: Juvenile initially seen by Bob Gunderson and reported by Aaron Maizlish this morning. Spent most of the time foraging at the north edge of the gravel bar, closely associating with two Western Sandpipers (allowing for a nice size comparison with the smaller birds). Showed typical buff underparts, nice gilded edging of the back feathers and, in flight, a whitish band around the rump.

    Details: Initially there were only two, accompanying the Ruff, but a flock coalesced on the gravel bar later in the afternoon, occasionally taking flight in a tight flock (spooked once apparently by a bright orange kite being flown over Crissy Field just to the west). [Count revised after examining photos]
