Sparkling-tailed Woodstar
Tilmatura dupontii
Male sparkling-tailed woodstars are 8.2 to 10.1 cm (3.2 to 4.0 in) long. Females are 5.8 to 7.5 cm (2.3 to 3.0 in) long. Twelve specimens weighed an average of 2.23 g (0.079 oz). Both sexes have a long, straight, black bill and a large white patch on each side of the rump. Males have metallic green upperparts, a grayish white breast, and dark metallic bronze green belly and flanks. Their gorget is metallic violet blue. The central two pairs of tail feathers are metallic bronze green. The outer three pairs are about four times as long as the inner pairs, giving a deeply forked tail. Voice: The sparkling-tailed woodstar's song is "a very high, thin, but musical squeaking in a continuous stream, rising and falling slightly and lasting for many seconds at a time." It is sung from a high exposed perch. It also occasionally gives "high, sharp, twittering chirps".

Stripe-breasted Starthroat
Heliomaster squamosus
The stripe-breasted starthroat is 11.2 to 12.4 cm (4.4 to 4.9 in) long and weighs 5 to 6.5 g (0.18 to 0.23 oz). Both sexes have a long, slightly decurved, black bill, a white streak behind the eye, and a white "moustache". Both have a forked tail but the female's is less deeply indented than the male's. Males in breeding plumage have bronzy green upperparts with an iridescent green crown. Their gorget is glittering violet and the sides of it flare out. Their underparts are greenish-black with a white stripe down the middle. The central tail feathers are black and the rest are dark blue-green. Voice: What is thought to be the stripe-breasted starthroat's song is "a subdued, buzzy scratchy warble 'bzzzrrrr..bzzzrrr..chi-chi-chi-chi..bzrrr'." It also makes "a liquid 'tsik'" call.
