Green-and-white Hummingbird

The green-and-white hummingbird is 10 to 11 cm (3.9 to 4.3 in) long. Males weigh about 6.0 g (0.21 oz) and females about 5.5 g (0.19 oz). Both sexes have a medium length straight bill with a blackish maxilla and a reddish mandible with a dark tip. Adult males have brilliant green to bronze-green upperparts and flanks. Their undersides are whitish from the chin to the undertail coverts with greenish spots on the sides of the chin and throat and sometimes some golden-green on the coverts. Their tail is grayish green to golden green. Voice: The green-and-white hummingbird's song is "a repeated short phrase of typically three squeaky notes, 'tseet-chew-chip … tseet-chew-chip ...'." Its call is "two rising high-pitched notes followed by a descending stuttering series, 'tsee-tseeet-tsi-tsi-tsi-tsi'." Both are very similar to those of its close relative the white-bellied hummingbird.
