Golden-tailed Sapphire
Chrysuronia oenone
The golden-tailed sapphire is 9.5 to 10 cm (3.7 to 3.9 in) long. Males weigh 4.7 to 6.3 g (0.17 to 0.22 oz) and females 4.3 to 5.3 g (0.15 to 0.19 oz). Both sexes of all subspecies have a slightly curved bill with a black maxilla and a black-tipped red mandible. Adult males of the nominate subspecies have a violet-blue head and throat. Their back is bright green that transitions through bronze-green to bright coppery coverts and a copper-bronze tail. Their breast is glittering green, their belly bronze-green, and underneath their tail, their coverts are bronze with whitish edges. Voice: The golden-tailed sapphire's song is variable, described as "a repeated rhythmic phrase, often starting with a burry note, followed by several very squeaky or scratchy notes, and ending with repeated chips." It also makes calls described as "a drawn-out metallic trill and shorter chipping notes."

Shining-green Hummingbird
Chrysuronia goudoti
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."
