Phalaropus fulicarius Cogswell 1949 May 21 - Dumbarton Bridge, Alameda Co., Calif. a flock of 21 were on the salt pond just N. of the road and closest to the open bay at about 10:15 a.m. They were feeding by jabs here & there at the surface - without whirling. The whole flock flew a short distance & re-commenced feeding meanwhile swimming rapidly back toward their original position. At this time I had the closest view of them: - about 1/2 had the whole back smooth gull gray" The other 1/2 had some of it smooth gray & some (especially nearest the bend of the wing & on the scapulars) dusky. - hind-neck was narrowly blackish (much darker than Peterso's plate indicates) - top of head Dusky to blackish thru eye - forehead white - bill shorter & stouter than "needle-like" but no yellow base noted.
