Steve picked up on this bird as being rather different from Black-chinned Hummingbirds. He writes:
"The primary tips are distinctly narrower, a bit straighter.  The back color is actually rather like that of a Broad-tailed Hummingbird, which would explain the narrow, straight primary tips.  And... the inner primaries do not form a straight line, but start to widen after P4 or so, consistent with a non-Archilochus parent. Such as a Broad-tailed."
