Violet-fronted Brilliant

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."
