Between mid-September and 18 October 1976 an immature Blue-footed Booby (Sula nebouxii) was present on New Hogan Reservoir, Calaveras County, California. This marks the first recorded inland occurrence of the species in northern California, although there was an earlier report from coastal Pacific Grove, Monterey County, of up to four observed on 16 and 17 October 1971 (DeSante et al., Am. Birds 26:112–118, 1972). Also, with one exception, the New Hogan Reservoir observation represents the northernmost recorded occurrence of the species. The exception is one procured in Puget Sound off Everett, Washington on 23 September 1935 (Larrison, Murrelet 26:45, 1945). All other western United States records are from southern California, western Arizona, and extreme southern Nevada (McCaskie, Calif. Birds 1:117–142, 1970; Monson, Am. Birds 26:100, 1972; McCaskie, Am. Birds 26:119–124, 1972).
