Chestnut-breasted Coronet

Appearance: The Chestnut-breasted Coronet is a medium-sized hummingbird measuring around 11 to 12 cm in length. It is known for its striking appearance, characterized by a rich chestnut-colored breast and belly. The upperparts are a shimmering green with a metallic sheen that is noticeable in sunlight. It has a relatively short, straight bill, which is common for hummingbirds that feed on flowers with short corollas. The tail is a mix of chestnut and green, adding to its  look.
Habitat: This species is found at elevations ranging from 1500 to 3400 m. It inhabits humid montane forests, cloud forests, and edges of forests. It is found in secondary growth and areas with abundant flowering plants.
Behavior: The Chestnut-breasted Coronet feeds on nectar from a variety of flowering plants. It is known for its aggressive behavior at feeding sites, often chasing away other hummingbirds. It exhibits the rapid and agile flight of hummingbirds, capable of hovering in place as it feeds. This species is quite territorial defending its feeding grounds vigorously against intruders.
Breeding: The nest is a small cup made of plant fibers and moss, usually placed on a sheltered branch or ledge. Little specific information is available about its breeding habits, but like most hummingbirds, it lays two white eggs per clutch.
Conservation Status: The Chestnut-breasted Coronet is considered of Least Concern by the IUCN.
