In elevation it ranges between 1,600 and 3,300 m (5,200 and 10,800 ft) in Ecuador, though is most numerous between 1,900 and 2,700 m (6,200 and 8,900 ft).

行为
The chestnut-breasted coronet's movements, if any, have not been documented.<p>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.<p>The chestnut-breasted coronet's breeding phenology has not been described. It is assumed to make a cup nest like other closely related hummingbirds.<p>One description of chestnut-breasted coronet vocalizations is "a high, thin, liquid tip, a rapid, sweet trill, and various squeaky notes."
