Taxonomy and systematics

The chestnut-breasted coronet shares genus ''Boissonneaua'' with two other coronets, the buff-tailed (''B. flavescens'') and velvet-purple (''B. jardini''). It is

monotypic In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unisp ...

Description

The chestnut-breasted coronet is long and weighs about . 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.Schulenberg, T. S. (2020).

Behavior

Movement

The chestnut-breasted coronet's movements, if any, have not been documented.

Feeding

The chestnut-breasted coronet is highly territorial and defends clusters of flowers from other nectar-feeding birds. It typically forages from the mid-story to the canopy. It feeds by clinging to the flower, holding its wings open for a second or two after landing. In addition to feeding on nectar it captures small insects by hawking from a perch.

has not been described. It is assumed to make a cup nest like other closely related hummingbirds.

Vocalization

One description of chestnut-breasted coronet vocalizations is "a high, thin, liquid ''tip'', a rapid, sweet trill, and various squeaky notes."

has assessed the chestnut-breasted coronet as being of Least Concern. It has a large range, but its population size and trend are not known. No immediate threats have been identified. It is considered uncommon to fairly common in Ecuador and uncommon to common in Peru. "Human activity has little short-term direct effect on Chestnut-breasted Coronet, other than the local effects of habitat destruction".
