On 15 May 1975, Ron Cole collected an adult male Ruby-throated Hummingbird (Archilochus colubris) at Sagehen Creek Field Station, 11 km north of Truckee, Nevada County, California (39°25′N, 120°15′W). The bird was freeze-dried as a study specimen (WFB-972, Museum of Wildlife & Fisheries Biology, University of California, Davis).
Because Ruby-throated Hummingbirds are not included in recent comprehensive publications on the occurrence of California birds (McCaskie et al. 1979; Garrett and Dunn 1981; Jones et al. 1981), or reported in the most recent reports of the California Bird Records Committee (Luther et al. 1983; Binford 1983, 1985), we conclude that this specimen represents the first record for the species in California.
