About These Birds
Ecuadorian Hillstar
A medium-sized hummingbird (12-13 cm) endemic to the highlands of Ecuador at 3,500-5,200 m, notably on Chimborazo volcano. Males have a violet-blue hood and white breast. One of the world's highest-living birds, adapted to extreme altitude with enhanced oxygen-carrying capacity.
Ruby-throated Hummingbird
The ruby-throated hummingbird is the only breeding hummingbird in eastern North America. These tiny birds beat their wings about 53 times per second and can fly backwards, sideways, and even briefly upside down. They make an extraordinary non-stop 800 km crossing of the Gulf of Mexico during migration.
