Identify this hummingbird?
I snapped a few photos of a hummingbird on our zinnias yesterday. I'm trying to identify the species. Since we're in Tennessee, I was guessing it is a female of either the Stellula calliope, Archilochus alexandri, or Calypte anna variety. But, I'm probably completely wrong. Does any one have an educated guess? The photostream is linked below.
