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.
Breeding The chestnut-breasted coronet's breeding
phenology 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." ==Status==
