This small hummingbird breeds along the Pacific coast of Oregon and California. Males display a reddish-orange throat and perform pendulum-like arcs followed by steep dives.
The body is coppery and green, and the male has a brilliant reddish-orange throat.
Males swing in pendulous arcs, climb high, and dive while making a sharp sound with their tails. Most winter in Mexico, while some remain in southern California.
