Until he moved a little, and the light hit his throat and head at the proper angle, and they flashed into painfully brilliant scarletness for a split second. Wow. He kept tilting his head this way and that, bringing out the color in little bursts. I couldn't possibly have moved until he did, so luckily he flew away before I was late for work.
I assumed that was a ruby-throated hummingbird, not having my new field guide with me to look it up, but a quick web search shows otherwise. It wasn't just a patch on his throat that was so bright, it was his whole head. I didn't know so many species had similar neck colorings. He did not, on further consideration, look like a ruby-throated hummingbird at all. Anna's hummingbird is more likely, I think now, and that's quite impressive enough although they're apparently common here. Either I've seen only females up till now, or the light's just never hit that perfect angle before. They really are amazing little creatures. They used to come to my calibrachoa on our third-floor apartment balcony once in a while.
