Selasphorus sasin, the genus name of the scarlet-throated Allen's Hummingbird, means “flame-bearing.” The female and immature hummingbirds of the two bird species are nearly impossible to distinguish. Allen's Hummingbird, along with Anna's Hummingbird, are the only two common nesting hummingbirds in Northern California's gardens.
