Call note as the bird approached feeder was reminiscent of Selasphorus 'tik', but more resonant, more musical, and slower cadence.

Similar species:

Iridescent feathers on crown and above eye eliminated all hummingbirds except Costa's.  The color of the iridescent feathers was deep pink to rosy red, not violet, ruling out Costa's. The measurements and overall size of the bird were larger than Costa's. Dark rachis extended into white tip of R5s.
