The Black Skimmer (Rynchops niger) was first found nesting at the south end of Salton Sea, Imperial County, California in 1972 (McCaskie et al. 1974). Five nests were found in 1972, three in 1973 (McCaskie 1973), and three in 1974 (McCaskie 1974). Nesting had been suspected at the north end of the sea, but was not confirmed until 16 August 1975 when the authors, Sandra Grant and Jeanne Hogg discovered eight nests on a small barnacle-covered island in the northeast corner of the sea.
