    This is a female Costa’s hummingbird – but I cheated – I found Mr. Ditch’s photo on flickr.

    Female Archilochus alexandri (Black-chinned hummingbird). Green back, black patterning at chin, dark wing edges. Range supports the Arizona find. Whoo, field guides! It might be Stellula calliope or Selasphorus platycercus, though — but its sides look too pale.

    As a side note, I’m a first time poster to your blog … I’m interested in birds and trying to learn more. Have got to admit, though, the talk about ‘rufous’ in the description means I need to do some more research … I have no idea what that is!

    The two-toned bill and the bright green upper rump patch lead me to Broad-billed Hummingbird.
