Bullion 1949 Erolia vairsii -1- Aug 17 Big Lagoon, Humboldt Co., Calif. - 1 of 2 birds collected on the mud flats beside the New Mouth of Maple Creek (see journal p. 124). These two birds were feeding with a flock of about a dozen Western Sandpipers and 1 Semipalmated Plover. These two sandpipers stayed a little apart from the other species, but flew with the other shore-birds. They were more tan or buff than the other birds, and were noticeably longer winged in flight. They were feeding right along the edge of the very shallow retreating water, in exposed Potamogeton.
