ID tip
The green-backed hillstar is 13 to 14 cm (5.1 to 5.5 in) long including its approximately 3 cm (1.2 in) bill. It weighs about 8.7 g (0.31 oz). The sexes are alike, though the female is somewhate duller than the male. They have bronzy green upperparts with bronzy uppertail coverts, an iridescent blue throat and breast, and a dull gray belly. Their central tail feathers are bronzy and the others white with dusky gray outer edges. Juveniles are similar to adults with the addition of buffy fringes on the head feathers and a slight buffy malar streak. Voice: What is thought to be the green-backed hillstar's song is "a continuous series of single 'tseee', 'tsing' or 'seeuw' notes". It also makes "a liquid 'twit', repeated in long sequences.
