Sun was on the bird when feeding on the flowers. Hot, dry, clear, sunny day. This bird did not have the jizz of either of those hummingbirds which would be considered more likely than Calliope. There was no rufous in the tail which elminates Rufous Hummingbird which, again, would be more likely than Calliope. Peterson's Western Birds.
Video shows that the wings extend almost exactly to the end of the tail.
Very short bill. The flanks of this bird were very buffy. No rufous in the tail. Typical hummingbird behavior. Sitting, preening, when not feeding.
