Chestnut-breasted Coronet
Boissonneaua matthewsii
The chestnut-breasted coronet is 10.5 to 13 cm (4.1 to 5.1 in) long and weighs about 6.5 to 8.3 g (0.23 to 0.29 oz). Both sexes have a short, straight, black bill, a white spot behind the eye, and a notched tail. Males have metallic green upperparts. Their throat has yellowish green speckles on a buff base and the rest of the underparts are reddish chestnut with some green speckles on the flanks. The central tail feathers are bronzy and the rest reddish chestnut with bronzy tips. The female's plumage is almost identical, but with somewhat paler underparts and less speckling on the throat. Voice: One description of chestnut-breasted coronet vocalizations is "a high, thin, liquid tip, a rapid, sweet trill, and various squeaky notes."

Males have a velvety black head with a glittering purplish blue crown; the rest of the upperparts are shining bluish green. The throat is velvety black and the breast and belly glittering purplish blue. The underwing coverts are cinnamon and show in flight. Voice: The velvet-purple coronet's courtship song is described as a "series of alternating harsh and soft whistles, 'si, siii, si, siii, si, siii...'".
