About These Birds
Oasis Hummingbird
A small hummingbird (12-13 cm including long tail) found in the arid coastal deserts of Peru and northern Chile. Dull plumage with a long, forked tail. Nectarivore specializing in desert flowers and columnar cacti. One of the few hummingbirds adapted to hyper-arid environments.
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.
