Tiny5 gForest

The blue-tufted starthroat is 12.6 to 13 cm (5.0 to 5.1 in) long and weighs 5 to 6.5 g (0.18 to 0.23 oz). Both sexes of all subspecies have a long, decurved, black bill and a small white spot behind the eye. Both have a forked tail but the female's is less deeply indented than the male's. Males in breeding plumage have an emerald green crown, nape, and upper back; the rest of the upperparts are shining coppery green. The throat is glittering violet. The underparts and elongated feathers on the sides of the neck are iridescent ultramarine. Voice: The blue-tufted starthroat does not appear to have a conventional song. It does make "a descending, pure-whistled 'tseep'" call.
