Look up pics of the Broad-tailed hummingbird. Those and the Black-chinned are the most common. The other one you may see is the Rufous. The male Rufous are cool looking with orange/red/gold throats.I don't have a pic, but these are much lighter in color and seem noticeably smaller than the black-chinned male we've had all year. They seem less aggressive and skittish as well.
