White-throated Mountain-gem Lampornis castaneoventris

Medium-sized hummingbird, male mostly green with bold white throat, white line behind eye, and blue crown. Gray tail in the western parts of range, blue in the east. Female not quite as colorful but still striking: bright buffy underparts with black cheek and white line behind eye. She is very similar to female Purple-throated Mountain-gem but has duller bronzy tail; only safely identified with a good view. A forest hummingbird that also comes out to edges and gardens, visits feeders.
