Mrs. Zippy?

Back blips begin here with my very first Canon 7D Mark II photograph.

It's often difficult to tell the difference between different species of female hummingbirds.  Black-chinned and Anna's look very much alike.  So do the Costa's. I'm fairly confident this is a Costa's, though, because it has more of a grey belly and a short bill.  Zippy is a male Costa's hummingbird.
