Song or call & method of delivery: Given from exposed perch in crown of cottonwood tree. (not describer in field notes) Call a very loud, emphatic "chup", given near lowest point of display arc flight path. 
Behavior: Singing and displaying. Display: J-shaped flight path - followed in both directions - bird hovers at both ends.

Similar species and
how were they eliminated:
No other hummingbird has reddish throat and crown. Seen in bright sunlight, the rose-red colr could not have been confused with purple throat and Crown of Costa's Hummingbird, which is an obviously small hummingbird (unlike the bird observed, which was noticeably large). 
Previous experience with this & similar species: I have experience with Anna's Hummingbird in California, so. Nevada and Arizona; experience with Costa's Hummingbird in Arizona; and Broad-tailed (which also has rd on throat) throughout the western U.S.
