Day Before Yesterday's Hummingbird Photos

I took these photos of what I thought was a hummingbird on Tuesday afternoon.  But when I came home and looked at them in the evening, for some reason the little birdie didn't look much like a hummingbird.  I let myself be persuaded that I'd made a mistake and put the photos aside.  Then yesterday, I saw it again -- at least I think it was probably the same bird, since it was spotted flitting among the very same trees and at the same time of day as on the day before -- and it was unmistakably a hummingbird.  So here are the photos, two days late.
