Evidently identifying hummingbirds is not as easy as I would like it to be. It is certainly a challenge as I am relatively new to Arizona Hummingbirds and I am convinced I miss-identified this as a broad-billed. According to my guide broad-bills do not have spots under their chin and she definitely does. Two things about this female are not right for it to be a broad-billed. The bill is black not red and it has spots on it's neck. In these pictures the bill is coated with pollen so it looks yellow. I think this is probably a Broad-Tailed female.
