Stripe-breasted Starthroat

The stripe-breasted starthroat is 11.2 to 12.4 cm (4.4 to 4.9 in) long and weighs 5 to 6.5 g (0.18 to 0.23 oz). Both sexes have a long, slightly decurved, black bill, a white streak behind the eye, and a white "moustache". Both have a forked tail but the female's is less deeply indented than the male's. Males in breeding plumage have bronzy green upperparts with an iridescent green crown. Their gorget is glittering violet and the sides of it flare out. Their underparts are greenish-black with a white stripe down the middle. The central tail feathers are black and the rest are dark blue-green. Voice: What is thought to be the stripe-breasted starthroat's song is "a subdued, buzzy scratchy warble 'bzzzrrrr..bzzzrrr..chi-chi-chi-chi..bzrrr'." It also makes "a liquid 'tsik'" call.
