Tiny3 gForest

The emerald-chinned hummingbird is 7 to 8.6 cm (2.8 to 3.4 in) long and weighs about 2.7 to 3.5 g (0.095 to 0.12 oz). Both sexes of both subspecies have a short, straight, dull black bill. The nominate adult male has metallic bronze green to greenish bronze upperparts. Its central pair of tail feathers are bronze green and the rest black with a faint bluish or bronzy gloss. All have brownish gray tips. Its face has a bold white spot behind the eye. Its chin and upper throat are brilliant metallic emerald green and the lower throat velvety black to dusky metallic bronze green. Voice: The emerald-chinned hummingbird's song is "a high, thin, slightly squeaking chipping, tsin, tisn-tsin tsin-tsin tsin-tsin, or tsi tsi tsi-si, tsi-tsi tsi tsi-tsi..." When foraging it gives "a liquid, rattling trill ... at times only single notes given, puip puip" and when perched "a sharp sii'ing".

Its tail is long and rounded; the feathers are mostly green with white tips and the outer three pairs have broad white edges. The area around the eye is dusky gray with white streaks above and below it. The underparts are iridescent golden-green. Voice: The white-tailed goldenthroat is vocal when foraging, giving a "fast-paced series of loud, excited 'spit' notes". It also gives a "dry 'tsip-tsip' in flight."
