Although Black-chinned is a possibility, Anna's would be way more likely. Did you observe any tail pumping while it was in flight?

No, I didn't see any tail pumping.

Ken-ichi may be right. I was going by the 2nd picture while looking at it on my phone and now that I see it bigger, it is a little more green than a BC would be.
