Hummingbirds are often sexually dimorphic, the males of many species showing an ornamental gorget that females lack. Males use this ornamental plumage to attract mates and establish a territory, while females build nests and care for the young alone. In Los Angeles, California, we observed a nesting Anna’s Hummingbird with male-like plumage on the crown and gorget but the rectrix morphology of a female—and it reared chicks. The extent of gorget development on this individual likely represents one of the most extreme examples of a male-plumaged female hummingbird yet documented.
