On 17 August 1974, while enjoying a day in the field with Jon Dunn, Philip Unitt and John Butler, I discovered a Rufous-necked Sandpiper (Calidris ruficollis) feeding with other small shorebirds at the south end of the Salton Sea, Imperial County, California. The exact location was at the mouth of the Alamo River about 1 km east of the Red Hill Marina, and the birds with which it was associating were Least (C. minutilla) and Western (C. mauri) sandpipers. Since the bird was in non-breeding plumage, some comments on its appearance and actions are in order.
