The male and female buffy hummingbird are similar in appearance but the female tends to be less brightly coloured, and there is considerable variation in shade between individuals. The back and upper parts of the bird are a dull green, the underparts pale cinnamon-buff and the belly and undertail coverts white. The tail is dull green with a transverse grey bar and a rounded end. There is a white spot behind the eye and the beak is slender and straight. The upper mandible is black and the lower one pale with a black tip. The bird ranges from 8.5 to 9 cm (3.3 to 3.5 in) in length.

Green-backed Hillstar

Urochroa leucura

Tiny11 gForest

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.
