About These Birds
Coppery Thorntail
A tiny hummingbird (7-8 cm) known from very few specimens collected in Bolivia. Coppery plumage. Almost nothing known about its ecology or current status. One of the most mysterious hummingbirds; possibly rare, possibly overlooked. Further fieldwork needed.
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.
