Gilded Sapphire
Hylocharis chrysura
The gilded sapphire is 8 to 10 cm (3.1 to 3.9 in) long and weighs 4 to 5 g (0.14 to 0.18 oz). Both sexes have a medium length, straight, coral red bill with a black tip. Adult males are mostly iridescent golden-green, with a pale rufous chin and a glittering golden-bronze tail. Adult females are almost the same, but duller overall and with a grayish lower belly. Juveniles are like the adult female with buff fringes on the feathers of the head. Voice: The gilded sapphire's song is "a repeated high-pitched, cricket-like trill of variable length". Its call is "a short dry rattle 'trrrt'."

Rufous-throated Sapphire
Hylocharis sapphirina
The rufous-throated sapphire is 8.4 to 9.1 cm (3.3 to 3.6 in) long. Males weigh 4.1 to 4.5 g (0.14 to 0.16 oz) and females 3.9 to 4.3 g (0.14 to 0.15 oz). Males have a medium length, straight, coral red bill with a black tip; females' bills have less red. The species gets its English name from the males' intensely rufous chin; females' chins are a paler rufous. Adult males have dark green upperparts with coppery violet uppertail coverts. Their throat, chest, and belly are iridescent violet-blue and their undertail coverts chestnut. Voice: The Venezuelan and Brazilian populations of rufous-throated sapphire have different songs. The former is "a series of 4–7 bright, high-pitched notes...repeated every few seconds, 'sping...sping...sping ...' or more bisyllabic 'sping...spewee...spewee...spewee'." In Amzonian and southeastern Brazil it is "an irregularly repeated, drawn-out, high-pitched downslurred 'seeeeeee'.
