The chestnut-breasted coronet (Boissonneaua matthewsii) is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae. It is found in Colombia, Ecuador, and Peru. The chestnut-breasted coronet shares genus Boissonneaua with two other coronets, the buff-tailed (B. flavescens) and velvet-purple (B. jardini). It is monotypic.
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.

GBIF citizen-science records
It is estimated from how often the Chestnut-breasted Coronet is recorded against all the birds logged in Podocarpus National Park (776 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
