Agreed: Anna's Hummingbird (Calypte anna). You don't say where you are in no. Calif., but, depending upon the area, you could also have Allen's, Black-chinned and Rufous during the summer. If you live near the coast, you may have the coastal subspecies of Allen's year-round.

No, but that's cool! I finally tracked it down. It's Red Rocket Russelia. (Russelia sarmentosa) Here is a link that might be useful: Russelia sarmentosa

I don't know what it is but it's beautiful! I love the colors!

Thanks everyone. I'm in Texas, so it is probably a black-chinned. I was thrown by the pink belly of what I believe is the male that visits the feeder. E-Nature is a great site.
