Violet-crowned Hummingbird
fieldmarks:
bill pink with black tip
olive back
range = Arizona
I'm going to say Broad-billed Hummingbird, based on the "long, curved bill" (Sibley), and the pattern of white on the head. Though there are other hummers with that orange-and-black beak that have plumage features matching this bird more closely: Sibley's illustration of the adult female White-eared has "rows of green spots" that look a lot like this bird, and Violet-crowned has white underparts that match this bird better. But White-eared should have a "white supercilium always striking", and Sibley's Violet-crowned looks much dingier in all plumages than this green little gem.
Whatever it is, it sure is pretty.
Haha. And now, having checked the answer in the back of the book, I... will not say anything more. Except the aforementioned "haha".
:-)
Male Broad-billed Hummingbird. Two-tone bill, and blueish cast to face and throat beginning to show. At least it looks like the more-fully developed males I saw in Santa Barbara CA a couple of decades or more ago...
The first two commenters noted characteristics typical of Violet-crowned and Broad-billed. Violet-crowned was my first impression, but it did not look quite right. The overall shape, extensively snow-white underparts, and dull back color point toward Violet-crowned parentage, but the color and shape of the tail suggest Broad-billed. An unusual Violet-crowned is possible, but I see that the experts are leaning toward a Violet-crowned X Broad-billed hybrid and will join them.
