Shining-green Hummingbird

The shining-green hummingbird is 9 to 9.5 cm (3.5 to 3.7 in) long. Males weigh about 4.1 g (0.14 oz) and females about 3.7 g (0.13 oz). Both sexes of all subspecies have a straightish bill with a black maxilla and a mostly pink mandible. Adult males of the nominate subspecies C. g. goudoti have green upperparts. Their underparts are mostly shining bluish green with a whitish belly and green undertail coverts with white edges. Their tail is forked; its central feathers are bronze-black and the outer ones blue-black. Adult females' upperparts are like the male's. Voice: What is thought to be the shining-green hummingbird's song is "a short, thin ‘lisping’ rattle initiated with an upslurred note...rapidly repeated 10–12 times, 'pee-rrrr..pee-rrrr..peer-rrrr..'." Its calls include "chips and a high-pitched descending trill."
