Great Sapphirewing
Pterophanes cyanopterus
The great sapphirewing is one of the largest hummingbirds; only the two of genus Topaza and the giant hummingbird (Patagona gigas) are larger. It is 15.5 to 19 cm (6.1 to 7.5 in) long including the 3.6 cm (1.4 in) bill. Males weigh between 9.6 and 11.2 g (0.34 and 0.40 oz) and females 8.4 to 11 g (0.30 to 0.39 oz). Both sexes have a small white spot behind the eye. Males of the nominate subspecies have dark shining blue-green upperparts. The wing is mostly shining blue and the tail greenish black. The underparts are also blue-green but somewhat bluer than the upperparts. Voice: The great sapphirewing's vocalizations include "a high, thin, liquid chatter", a "drawn-out piercing high-pitched zeee", and " agitated titititirrr".

Violet-fronted Brilliant
Heliodoxa leadbeateri
The violet-fronted brilliant is 11 to 13 cm (4.3 to 5.1 in) long. Males weigh 7.1 to 8.5 g (0.25 to 0.30 oz) and females 6.6 to 7.5 g (0.23 to 0.26 oz). Both sexes have a medium length, almost straight, black bill, a white malar streak, and a small white spot behind the eye. They both have a forked tail but the female's is less deeply indented than the male's. Males of the nominate subspecies have bronzy green upperparts with a glittering blue forehead and a coppery neck. They have a glittering emerald green gorget and a dull bronzy green breast and belly. Voice: What is thought to be the violet-brilliant's song is "a continuous series of single strident 'chup' or 'tchep' notes". It also makes "a repeated, bright, descending phrase 'whee-tsee-tsee-tsew' that sounds like a jerky twittering."
