The Ecuadorian Hillstar (Oreotrochilus chimborazo) is a remarkable hummingbird species found primarily in the high-altitude regions of Ecuador, especially around the Andean mountains.

Known for its unique adaptability to colder environments, this bird thrives at altitudes of up to 5,200 meters. The male features a striking iridescent green body with a white throat and a dark blue crown, while the female is more muted in coloration.

Ecuadorian Hillstars feed on nectar from hardy mountain flowers, using their specialized long beaks, and are well-adapted to survive in challenging, cold environments.
