Red-tailed Comet
Sappho sparganurus
Male red-tailed comets are 19 to 20 cm (7.5 to 7.9 in) long including their 7 to 10 cm (2.8 to 3.9 in) tail. Females are 12 to 14 cm (4.7 to 5.5 in) long. The species weighs about 4 to 6.5 g (0.14 to 0.23 oz). Adult males of the nominate subspecies have a shining green head with a golden green or emerald green gorget. Their back and rump are reddish purple and their underparts mostly green with buffy undertail coverts. Their tail is long and deeply forked. Its upper surface looks reddish purple to green depending on the angle of the light striking it. Voice: What is thought to be the red-tailed comet's song is "a short, rapid, jumbled chatter". It also makes an "unmelodic tjrrrt" and "rather harsh tsha or zack notes, which may be monotonously repeated at more than 1 s intervals".

White-bellied Hummingbird
Elliotomyia chionogaster
The white-bellied hummingbird is 9 to 12 cm (3.5 to 4.7 in) long. Males weigh 4.9 to 6.7 g (0.17 to 0.24 oz) and females 4.5 to 6 g (0.16 to 0.21 oz). Both sexes of both subspecies have a medium length straight bill with a blackish maxilla and a reddish mandible with a dark tip. Adult males of the nominate subspecies have brilliant light green upperparts, sides, and chest. Their undersides are whitish from the chin to the undertail coverts with golden-green spots on the sides of the throat and sometimes some green on the coverts. Voice: The song of the nominate white-bellied hummingbird subspecies is "a repeated short phrase typically comprising three squeaky notes, 'tseet-chew-chip … tseet-chew-chip …'." That of E. c. hypoleuca is "a series of single high-pitched, penetrating 'pseek' notes, occasionally followed by a lower-pitched, faster 'tsi-tsi-tsi-tsi'.
