Calliphlox amethystina
The amethyst woodstar is 6 to 8.4 cm (2.4 to 3.3 in) long and weighs 3.2 to 2.5 g (0.11 to 0.088 oz). Both sexes have a medium length, straight, black bill. They have dark bronzy green upperparts with a large white spot on either side of the rump. Males have a small white spot behind the eye while females have a thin white stripe. Males in breeding plumage have an iridescent amethyst gorget with a whitish band below it. The rest of the underparts are greenish with brownish lower flanks. Its deeply forked tail is purplish black with green tips to the feathers. Voice: Very few recordings of the amethyst woodstar's vocalizations are known. Its song has not been described. Its call is a "low, very sharp rattle, like 'trr'."

Puerto Rican Emerald
Riccordia maugaeus
Male Puerto Rican emeralds are 8.5 to 9.5 cm (3.3 to 3.7 in) long and females 7.5 to 8.5 cm (3.0 to 3.3 in). The species weighs between 3.4 and 3.8 g (0.12 and 0.13 oz). Both sexes have a small white spot behind the eye. Males have a short straight bill with black-tipped red mandible and a black maxilla. Its forehead and crown are iridescent green; the rest of its upperparts are dark shining metallic green. Its gorget is iridescent bluish green and the rest of its underparts are shining green. The tail is forked and shining steely blue. The female's bill is all black. Voice: What is believed to be the Puerto Rican emerald's song is "a repeated twittering phrase of high-pitched descending notes followed by a series of ‘lisping’ notes on constant pitch 'tseereetseetseetsee-tslew-tslew-tslew-tslew-tslew'". It also makes "high-pitched 'tsik'" and "si..si..sik-sik...tsik.." calls.
