On the afternoon of 30 January 1988, Art Edwards, Peter Willmann and I were birding at 157 Via Baja in Ventura, Ventura County, California. Virgil Ketner, of 169 Via Baja, was also there to show us the adult male Broad-billed Hummingbird (Cynanthus latirostris) that had been coming to his and his neighbor’s feeders. The weather was clear, calm, hazy, the temperature about 60°F. About 1430, while waiting for the Broad-billed Hummingbird to reappear, I heard a buzzy chatter coming from a blooming bottlebrush tree, then saw an unfamiliar hummingbird in it. I called the others over to look at the bird, and Edwards and I saw it hovering in the shaded bottlebrush for perhaps 10 seconds before it flew off. I wrote the following description about 10 or 15 minutes after my observation: Moderate size hummingbird. All green back. All pale rufous-beige underparts. Green crown. White face with broad sooty eye line, much broader than the white borders above and below it. Dark bill. Feeding in bottlebrush. Low-pitched buzzy chatter.
