Amethyst Woodstar
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'."

Many-spotted Hummingbird
Taphrospilus hypostictus
The many-spotted hummingbird is 10.5 to 11.4 cm (4.1 to 4.5 in) long and weighs 6.7 to 9 g (0.24 to 0.32 oz). Both sexes have a slightly decurved black bill about 2.3 cm (0.91 in) long, and their plumage is very similar. Adults' upperparts are grass green to coppery bronze and the underparts white. The underparts except the central belly are thickly spotted with green, the female's somewhat less heavily. Their tail is blue-green with dusky gray tips to the feathers. Juveniles are the same with the addition of buffy fringes on the head feathers. Voice: The many-spotted hummingbird's song is a "quiet series of wheezy, electric warbles and gravelly-sounding chatters". It also makes calls described as "a thin-sounding 'chit' and a wheezy 'dew dew dew'."
