Golden-tailed Sapphire
Chrysuronia oenone
The golden-tailed sapphire is 9.5 to 10 cm (3.7 to 3.9 in) long. Males weigh 4.7 to 6.3 g (0.17 to 0.22 oz) and females 4.3 to 5.3 g (0.15 to 0.19 oz). Both sexes of all subspecies have a slightly curved bill with a black maxilla and a black-tipped red mandible. Adult males of the nominate subspecies have a violet-blue head and throat. Their back is bright green that transitions through bronze-green to bright coppery coverts and a copper-bronze tail. Their breast is glittering green, their belly bronze-green, and underneath their tail, their coverts are bronze with whitish edges. Voice: The golden-tailed sapphire's song is variable, described as "a repeated rhythmic phrase, often starting with a burry note, followed by several very squeaky or scratchy notes, and ending with repeated chips." It also makes calls described as "a drawn-out metallic trill and shorter chipping notes."
